AB  - The aim of the study was the comparative analysis of degradation of wheat straw lignin by white-rot fungi and its  implications on the efficiency of enzymatic hydrolysis of holocellulose. Peroxidases were found to be predominantly  responsible for lignin degradation, even though high laccase activities were detected, especially in the initial stages of  fungal culturing. The studied fungal species showed various ability to degrade lignin in wheat straw, which further  affected the release of reducing sugars during enzymatic saccharification. The highest rate of lignin, hemicelluloses and  cellulose degradation was noticed in the sample pretreated with Irpex lacteus. Among all the tested species, only  Ganoderma resinaceum was found as a suitable lignin degrader, with 2-fold higher hydrolysis yield (51.1 ± 4.7%) than  in the control. A key mechanism that enhances convertibility of carbohydrates is the selective lignin removal from biomass. Operating time, holocellulose loss and unpredictable fungal response to culturing conditions are the main  challenges in fungal pretreatment of lignocellulosic feedstock.

AB  - Various studies report contrasting results on the substrate-type effect on diatom community composition, but the particularly important question is whether or not it affects diatom-based assessments of water quality. We investigated whether the substrate type is a significant predictor of the diatom community composition and if it affects lake water quality assessment based on diatom indices. This study took place in Sava Lake (Serbia). We used glass, ceramic, willow and yew tree tiles as artificial substrates for periphyton development, and pebbles from the lake littoral as natural substrate. Results revealed differences in both the diatom community composition and diatom indices values related to the substrates. A distinction was recognized between natural, artificial wooden, and artificial inert substrates. However, the final lake quality assessment based on diatom indices was more or less similar in all substrate types in our study, and depended on value ranges associated with water quality classification and on diatom index choices. Artificial substrates in our study did show potential as an alternative for natural substrate, but further studies are required, particularly in various types of lentic ecosystems to confirm our findings and support artificial substrate employment in lake water quality assessment.

AB  - The importance of biofilms in caves, the diversity of microorganisms
in them, their mutual relationship and relationship with the substratum are among the advancing research topics in microbial biospeleology. This research is making contribution to the
knowledge about biofilms at cave entrances and phototrophic communities in them. In that
manner, biofilms from the entrance zone of the Petnica Cave were examined. Light microscopy showed that cyanobacteria were exclusively dominant phototrophs (34 taxa out of 39
total taxa recorded) with coccoid forms prevailing (28 taxa); simple trichal forms were present to a lesser extent, while heterocytous ones were completely absent. Genera Gloeocapsa,
Chroococcus,Gloeothece and Leptolyngbya were the most diverse. Four green algal genera
characteristic for aerophytic habitats (Apatococcus, Desmococcus, Haematococcus and
Trentepohlia) were also recorded, while Bacillariophyta were observed sporadically. Three
groups of sampling sites were distinguished based on recorded taxa, their richness and similarity, using non-metric multidimensional scaling (NMDS). Quantitative biofilm characteristics were also assessed – the content of chlorophyll a (Chl a) was determined, as well
as the contents of water, organic and inorganic matter. Chl a had a significant positive correlation with the content of organic matter (r=0.904, P=0.013).

Ово истраживање доприноси општем познавању биофилмова на улазима пећина, као и познавању фототрофних заједница које се налазе у њиховом саставу. Имајући то у виду, испитивани су биофилмови са улазне зоне Петничке пећине. Светлосна микроскопија је показала да су цијанобактерије искључиво доминантни фототрофи 
(забележено је 34 од укупно 39 таксона), са изузетном доминацијом кокоидних форми (28 таксона); трихалне форме (хомоцитни представници) су у биофилму заступљене у мањој мери, док су хетероцитне потпуно одсутне. У родовима Gloeocapsa, Chroococcus, Gloeothece и Leptolyngbya документован је највећи број таксона. Четири рода зелених алги која су иначе карактеристична за аерофитска станишта (Apatococcus, Desmococcus, Haematococcus и Trentepohlia) су такође забележена, док су представници раздела Bacillariophyta нађени спорадично. Статистичка анализа NMDS је показала да су се према сличности, односно на основу таксона који су идентификовани, одвојиле три групе тачака узорковања. Kвантитативне карактеристике биофилма су такође процењене – одређен је садржај 
хлорофила а (Chl a), као и садржај воде, органске и неорганске материје. Значајнa

AB  - An extensive aeromycological survey was performed in the premises of a cultural heritage conservation facility to estimate fungal propagule concentrations in both indoor and outdoor air and seasonal dynamics with regard to temperature and air humidity. The highest average propagule concentration in indoor air was documented in spring, and for outdoor air, in summer. Increased propagule loads were documented in most rooms during winter, fall and spring, and in all examined rooms in summer. Very high propagule concentrations (>25,000 CFU m−3) were reported in ground-floor rooms. The total mycobiota was comprised of 74 fungal species, with a prevalence of Aspergilli and Penicillia. Cladosporium and Penicillium isolates were found to be the most abundant in all seasons in both indoor and outdoor air samples. Among the identified fungi, potential human pathogens, allergens and mycotoxin producers were present. Numerous documented species play an important role in the deterioration of cultural heritage artifacts and are known producers of extracellular enzymes, acids and pigments. Application of a selective medium (M40Y) allowed isolation of various xerophiles and xerotolerant species. Aeromycological analyses are mandatory for determining the appropriate conditions for the protection of the health of conservators, as well as the objects of cultural heritage.

AB  - The main aim of this study was to investigate the application of benthic diatoms and the efficiency of diatom
indices in water ecological assessment of rivers in Serbia, as well as the influence of trout farms on rivers water
quality. Research was conducted in one year period along the Crnica and Radovanska rivers (Eastern Serbia), in
11 sampling sites (taking into account the position of trout fish farms that are built on both rivers). Results
showed that fish farms affect the physical and chemical parameters, as well as diversity of the epilithic diatom
assemblage along the rivers. Canonical correspondence analysis (CCA) indicated that among tested physical and
chemical parameters, conductivity “EC”, water hardness “WH”, sulfates “SO42-”, ionized ammonia fraction “NH4+”,
nitrates “NO3–
“, “pH”, mud, stone and depth were the most important variables affecting the distribution of
diatom species. A total of 206 epilithic diatom taxa were recorded in the Radovanska and 170 in the Crnica River.
Based on diatom indices, trout fish farms have no significant negative impact on the water quality of the
investigated rivers (indices are not enough sensitive). Redundancy analysis (RDA) showed a high degree of
correlation between the majority of indices which mostly indicated to good water quality of studied rivers. TID
and TDI were the only two indices indicating moderate and poor water quality of both rivers. Water quality based
on the TIDRS, the first proposed diatom index for Serbia was differ in two classes in most sites compairing with
TID.

AB  - Lampenflora communities of bacteria, cyanobacteria, algae, mosses and lichens colonize illuminated show-caves as a consequence of disturbances to the caves’ ecological equilibrium. These communities have unesthetic impacts and can cause the biodeterioration of limestone. A 15% hydrogen peroxide solution was proposed for use as an ecological agent for the safe removal of these microorganisms. This study tested the effects of three different biocides (hydrogen peroxide, a commercial solution containing salicylic acid and a product containing chlorine dioxide as the active component), on the growth of green algae (Chlorella sp.), which are frequently encountered in lampenflora communities. Chlorella sp. was treated with the biocides under laboratory condition, and chlorophyll a (Chl a) concentrations were measured 1 h, 3 days, 7 days and 10 days after treatment. The change in Chl a concentration was compared to the untreated control group at each time point. All three biocides prevented the growth of green algae and the product containing chlorine dioxide appeared to be the most effective growth inhibitor. Hydrogen peroxide is known to suppress lampenflora growth in caves, and further studies on other biocides remain necessary to identify a solution that is both ecologically safe and economically feasible.

AB  - Aerophytic phototrophs, colonizers of different substrates exposed to air, among which are rock substrates in cave habitats, are in general not sufficiently investigated and studied. From the ecological point of view, seasonal/temporal variations and parameters that influence aerophytic phototrophic communities through seasons still remain largely unknown. Seasonal analysis of phototrophic microorganisms from biofilms developed at entrances of Samar and Jezava caves in Eastern Serbia was performed four times a year. All identified phototrophic representatives were assigned to a certain division or group. The relationship between documented groups and different measured, determined and observed ecological parameters was illustrated using principal component analysis (PCA). A high diversity of cyanobacteria and algae was observed as a result of seasonal sampling: 141 taxa in Samar and 61 taxa in Jezava Cave. Cyanobacteria were dominant in both caves (coccoid forms prevailing) and were followed by Bacillariophyta. Bacillariophyta were positively correlated with light intensity and sites where seeping water was present, and cyanobacteria with water content in biofilm, Chl a and relative air humidity. Higher diversity of phototrophs was documented in December and March, and lower in May and August in both caves with Chl a values having the same trend as the diversity of phototrophic microorganisms. This was especially the case with biofilms in which diversity was more prone to seasonal changes and where Cyanobacteria dominated. Only 24 taxa were documented during all four seasons in Samar Cave (Cyanobacteria, Bacillariophyta and Chlorophyta representatives) and three in Jezava Cave (Cyanobacteria only).

AB  - Phototrophic microorganisms from two caves in Serbia (Podpeć and Stopić) were examined. Samples were taken from the entrances where natural light was present, as well as from the inside caves near artificial light (lampenflora community). Cyanobacteria, Chlorophyta, Bacillariophyta and Xanthophyta were documented, with 51 taxa in total. The highest number of taxa recorded in the Cyanobacteria were coccoid cyanobacteria; Gleocapsa and Chroococcus were dominant. According to the redundancy analysis (RDA), Cyanobacteria were dominant at cave entrances while other groups (Chlorophyta, Bacillariophyta and Xanthophyta) were documented in lampenflora samples. Temperature, relative humidity, and light intensity were measured, as well as chlorophyll a concentrations and biofilm parameters (water, organic and inorganic matter content). Ecological parameters did not show significant variation, while light intensity de-pended on the position of sampling sites. RDA showed that the water content was higher in biofilm samples from cave entrances, while levels of inorganic matter were increased in lampenflora samples. The concentration of chlorophyll a did not show significant correlations with any of the measured ecological or biofilm parameters. Although the ecological parameters inside the cave did not show significant variation, they should be monitored because of the potential influence on the development of the lampenflora community that has a negative aesthetic impact on cave formations.

AB  - Phosphorus overenrichment of shallow ponds prevailing in wetlands leads to their eutrophication causing the collapse of those vulnerable habitats. The potential of phosphorus accumulation by periphyton developed on artificial substrata has been investigated in two shallow ponds (Baračka and Široki Rit) in northwest Serbia and compared to the same ability of plankton and metaphyton. The periphyton substrate carrier has been submerged from May to October. Both continuously (CS) and monthly developed (MS) periphyton were sampled. Autotrophic component of all investigated communities has been qualitatively assessed. Maximum accumulation of only 14.7 mg TP/m2 was recorded in three-month exposed periphyton CS. MS exposed from July to August reached maximal 12.7 mg TP/m2. Plankton community that was characterized by more diverse and abundantly developed algal component was more effective in phosphorus accumulation (0.7 mg/g dry weight) in comparison with dominantly inorganic and diatom-dominated periphyton in Baračka. Unstable conditions caused by recent revitalization (dredging organic matter and mud from pond basin—redigging) as well as rapid desiccation of Široki Rit disabled making an unambiguous conclusion about the efficiency of phosphorus accumulation among different communities, but suggested slight potential of phosphorus harvesting by metaphyton in this pond. Due to the shorter exposure time that brings the reduced risk of unpredictable changes in the ecosystem, as well as the considerable amount of accumulated phosphorus, large-scale application of one-month exposed periphyton developed on artificial substrates would be more advisable for phosphorus harvesting in nutrient affected shallow ponds.

Unstable conditions caused by recent revitalization (dredging organic matter and mud from pond basin—redigging) as well as rapid desiccation of Široki Rit disabled making an unambiguous conclusion about the efficiency of phosphorus accumulation among different communities, but suggested slight potential of phosphorus harvesting by metaphyton in this pond. Due to the shorter exposure time that brings the reduced risk of unpredictable changes in the ecosystem, as well as the considerable amount of accumulated phosphorus, large-scale application of one-month exposed periphyton developed on artificial substrates would be more advisable for phosphorus harvesting in nutrient affected shallow ponds.",

AB  - Phototrophic microorganisms can be found in biofilms at entrances to caves where they have access to sufficient
sunlight, water and nutrients; however, they can also be found inside caves, where they are carried by animals and people, and
can proliferate in the presence of artificial light. Although the genus Humidophila includes some well-known cosmopolitan
species, further exploration of its rare, insufficiently investigated representatives in different geographical areas and unusual
habitats is necessary. Caves remain unknown, little-explored habitats, and many species currently known to science were
recorded for the first time. This study aimed to report species belonging to the genus Humidophila that were identified in
19 caves in Serbia. A total of ten species of this genus were recorded and some of them are documented for the first time
in Serbia. The most abundant species were H. contenta (found in 16 caves), H. paracontenta, and H. aerophila (found in 13
caves), whereas H. pyrenaica was identified in only one cave. The rare species, H. brekkaensoides and H. vidalii, were also
documented and described, but with different dimensions from those provided in current identification keys.

AB  - Domination of certain aerophytic phototrophic group or specific taxon in biofilms is connected with biofilm features recognised in situ. Well-developed, gelatinous, olive to dark-green biofilms are composed mostly of coccoid cyanobacterial forms. The same features, characterised biofilms dominated by one coccoid taxon, except the latter were vividly coloured. Gloeobacter caused the appearance of purple, Gloeocapsa representatives yellow and Chroococcidiopsis black biofilm. The brown to the dark colour of heterocytous biofilms was mainly caused by Nostoc. Simple trichal Cyanobacteria were occasionally present in biofilm, except in one blue-coloured sample. According to the principal component analysis (PCA), well-developed and gelatinous biofilms were correlated with Cyanobacteria, while scanning electron microscopy (SEM) revealed richness of extracellular polymeric substances (EPS) in such biofilms. Biofilm with calcified cyanobacterium (Geitleria cf. calcarea) was also found. Chlorophyta-abundant biofilms (many rich in Desmococcus), thinner than cyanobacterial, were predominantly green and occasionally yellow and blue. Many were dry when observed in situ (confirmed with PCA), with few being moistened (i.e. Klebsormidium-dominant). Diatom biofilms were usually developed on sediment, mosses or near seeping water (demonstrated by PCA) and were also thinner than cyanobacterial ones. Compared to cyanobacterial biofilms, SEM showed less developed EPS in those rich in diatoms and green algae, where microorganisms are more exposed to the environment. The study demonstrates an easy method for biofilm assessment based on visual characterisation and provides encouragement for more frequent biofilm investigation in caves that can be important from an ecological, biological, biotechnological point of view and which assessment can have an irreplaceable role in potential monitoring and protection.

AB  - Cyanobacterial blooms have become common all over the world, negatively affecting various ecosystem components. Planktothrix rubescens is a planktonic cyanobacterium that frequently causes blooms in temperate (mostly mesotrophic) lakes in Europe and, unlike other cyanobacteria, it is usually associated with ecosystem re-oligotrophication. The potential effects of P. rubescens on periphyton development have not been estimated in any recently published studies. The objective of the present paper was to assess how a Planktohrix rubescens bloom affects periphyton development in a temperate freshwater reservoir. A field study was performed in the Vrutci reservoir (western Serbia), where P. rubescens blooms have occurred since December of 2013. Periphyton was grown on glass slides that were incubated following lake stratification and sampled monthly from July to October of 2015. Dry mass, ash free dry mass and content of chlorophyll a, as well as composition of the community of developed periphyton, were estimated, together with P. rubescens biomass in the water column at the particular depths where substrates for periphyton were incubated. The metalimnetic bloom of P. rubescens induced calcite precipitation on the incubated substrates, which was reflected in obstructed colonization. The periphyton community composition was mainly determined by the depth gradient, which was potentially related to reduced light availability driven by shading effects caused by the P.rubescens bloom. Our results provide a significant update on periphyton ecology in relation to cyanobacterial blooms, elucidating complex interactions in the ecosystem. They also represent a stimulus for further studies on the capacity of P. rubescens for induction of calcium carbonate precipitation in lakes.

AB  - Due to life in extreme environments, cyanobacteria and algae from cave biofilms that form at the entrances or deep inside the cave around artificial lights are of increasing interest to many scientists. It is well-known that many phototrophic microorganisms are first to colonize exposed substrata and produce the organic matter on which other biofilm constituents relly. Many studies dealing with phototrophic microorganisms from biofilms focus on the diversity and community composition of cyanobacteria and algae, while quantitative assessments are rarely implemented. Biofilm sampling was conducted in Degurić and Vernjikica Cave located in Western and Eastern Serbia, respectively. Ecological parameters (temperature, relative humidity, light intensity) and distance from the entrance were measured. Additionally, chlorophyll content, as well as biofilm parameters (water content, organic and inorganic matter) were determined. The abundance of phototrophic microorganisms was assessed on microscope slides which contained 1 mg of biofilm that was dehydrated for a short period of time and homogenized prior to slide preparation, and then rehydratated. The biomass of recorded cyanobacterial and algal taxa was calculated by applying geometric approximations and standard mathematical formulas. In Degurić Cave, at the sampling site where the highest biomass was documented, the higher diversity, water content and chlorophyll values were also recorded, while in Vernjikica Cave a high content of organic matter was documented. According to the multivariate analyses performed, the biomass of simple trichal Cyanobacteria, Bacillariophyta, and Xanthophyta was positively correlated with the content of organic matter in biofilm and light intensity, while coccoid and heterocytous Cyanobacteria and Chlorophyta showed a positive correlation with water content in the biofilm, relative humidity and distance from the entrance. The total biomass was positively correlated with the chlorophyll content, organic matter and light intensity, and negatively with the distance from the entrance.

AB  - Investigations focusing on wellhead encrustations within select zones of emergence of mineral water, in different hydrogeological provinces, were conducted from 2014 to 2017 in Serbia. They included: well BB-1 in Bogatić (Inner Dinaric Alps of western Serbia), wells LB-4 and LB-5 in Lukovska Banja (Šumadija-Kopaonik-Kosovo Province), and wells VG-2 and VG-3 in Vranjska Banja (Serbian Crystalline Core). The studied occurrences belong to the group of hot mineral waters, with temperatures ranging from 62°C to 93.9°C, and total dissolved solids (TDS) from 600 to 1267 mg/L. They are mildly acidic to mildly alkaline (pH 6.6 – 8.0) and their genetic types are HCO3 --Na++K+ (Bogatić and Lukovska Banja) and SO4 2-, HCO3 --Na++K+ (Vranjska Banja). Macroscopic, optical and diffraction assessment revealed that the encrustations comprised calcite and aragonite minerals, along with some local quartz, muscovite, albite and clinochlore. The conclusion was that there was a predominant presence of calcium carbonate in all the occurrences, represented by crystalline calcite grains, characteristically birefractive, and dark, semitranslucent grains in the form of microcrystalline calcite highly stained by iron hydroxides (Bogatić), as well as crystalline calcite with radially developed carbonate - aragonite (Lukovska Banja) and rod-like and filamentous aggregates of aragonite and calcite, highly translucent in places (Vranjska Banja).The texture of the samples exhibits alternating horizontal or wavy carbonate laminae. In Vranjska Banja, they include thin micritic to medium crystalline laminae and laminae composed of aggregates of aragonite needles in the form of bunch. In Bogatić and Lukovska Banja, there are thick micritic and highly porous laminae, 0.025 to 1 mm thick, or interlayers of a coarser crystalline structure. Apart from encrustations, all the occurrences exhibit phototrophic microbial mats, which were analyzed by scanning electron microscopy. The onset and progress of encrustation are primarily influenced by the physical and chemical composition of the mineral water (T, pH, TDS, HCO3 -, Ca2+, CO2, etc.), as corroborated by hydrogeochemical modeling software PHREEQC 3.4.0. In addition, phototrophic biofilms might be contributing to the creation and accumulation of minerals in the encrustations.

abstract = "Investigations focusing on wellhead encrustations within select zones of emergence of mineral water, in different hydrogeological provinces, were conducted from 2014 to 2017 in Serbia. They included: well BB-1 in Bogatić (Inner Dinaric Alps of western Serbia), wells LB-4 and LB-5 in Lukovska Banja (Šumadija-Kopaonik-Kosovo Province), and wells VG-2 and VG-3 in Vranjska Banja (Serbian Crystalline Core). The studied occurrences belong to the group of hot mineral waters, with temperatures ranging from 62°C to 93.9°C, and total dissolved solids (TDS) from 600 to 1267 mg/L.

AB  - Aerophytic phototrophs (cyanobacteria and algae) represent special group of microorganisms capable to inhabit various substrates exposed to air, as long as the conditions for their settlement (substrate properties) and development (ecological parameters) are favourable. Rock surfaces are often susceptible to colonization of microorganisms, whether they are manmade or natural (exposed or hypogean – caves). Phototrophic biofilms that develop on rock substrates in caves (walls, ceilings, stalactites, stalagmites and other formations) are very common at naturally or artificially illuminated sites. Even though their proliferation is triggered by light and ecological/microclimatic parameters, interactions with the substratum still remain largely unknown. It is evident that substrate properties play an important role in settlement of these microorganisms and initiation of biofilm development, but further, it is uncertain to what extent contribute to their growth. Generally rocks are composed of many minerals that can be directly absorbed by cyanobacteria and algae when dissolved in water. For the purpose of this study, phototrophic microorganisms (cyanobacteria and algae) from biofilms developed on rock substrates were explored and petrographic analysis was performed in 15 Serbian caves. Considering phototrophs, four divisions (Cyanobacteria, Bacillariophyta, Chlorophyta and Xanthophyta) were recorded, and considering petrographic analysis, examined samples showed the domination of limestone with five different varieties recognized. The relationship between phototrophs and limestone varieties (divided due to different petrographical characteristics) was represented using PCA. Recrystallized, organogenic, microsparitic, micritic and clastic limestone were all separated along first PCA axis. This trend may be the consequence of different physical characteristics of these limestone types, such as porosity. However, certain phototrophc groups were connected to certain limestone types, i.e. Bacillariophyta showed positive correlation with clastic limestone, less with microsparite and micritic, while Cyanobacteria were correlated to the other two limestone types. Chlorophyta and Xanthophyta did not have clear separation according to substrate.

AB  - Phototrophic biofilms can be found in different habitats, including subterranean ones, such as caves. In caves, they thrive in the presence of daylight at the entrances, or in the vicinity of artificial light inside, and are usually very heterogeneous. For the purpose of this study, biofilm sampling from stone substrata was performed in 15 caves (mostly entrances) to examine biofilm characteristic and features, as well as to record the main phototrophic groups. Cyanobacteria, Bacillariophyta and Chlorophyta were the main phototrophs recorded. Cyanobacteria were, according to morphological characteristics, additionally divided into coccoid, simple trichal and heterocytous forms. Biofilms were sorted according to the degree of development and moisture (taking into account free seeping water and water bound in extracellular polymeric substances (EPSs)). Other parameters, namely the water content and content of organic/inorganic matter were determined too. According to the principal component analysis (PCA), Bacillariophyta and Chlorophyta were usually dominant in thin biofilms: while Chlorophyta were connected with dry thin biofilms, Bacillariophyta were abundant in thin biofilms constantly moistened by seeping water. Cyanobacteria dominated in thick and EPSs rich biofilms that also were positively correlated with light intensity and higher values of chlorophyll a. Biofilms were also sorted according to colour, where certain colours or colour assemblages corresponded to whole divisions, cyanobacterial groups or even only one taxon. Chlorophyta rich biofilms were mostly green, only few of them yellow and orange, while those where Cyanobacteria accounted as the most abundant, were very colourful (red, purple, blue, yellow, brown), for which usually only one species was responsible. Scanning electron microscopy (SEM) has additionally helped us to distinguish different biofilm types and their morphology better and enabled detailed analysis of distribution, shape, size and orientation of biofilm constituents. The biofilm rich in Cyanobacteria with calcified filaments occurred as particularly interesting for SEM exploration.

AB  - Diatoms (Bacillariophyta) are widespread microorganisms that were found in different aquatic ecosystems, but also in other habitats, such as stone substrates exposed to air. There diatoms thrive with other phototrophic organisms (cyanobacteria and algae) if they have sufficient sunlight, water and nutrients. Phototrophic organisms penetrate into tourist caves where artificial lights support their growth. This community in the vicinity of lights, so called lampenflora, includes bacteria, cyanobacteria, algae, fungi, mosses and lichens. Despite cave diatoms in Serbia have been studied several times, the knowledge about this group is scarce. Epilithic diatoms were collected by scraping biofilms from the entrance (two sampling sites) and the inside (four sampling sites) of Resavska Cave (eastern Serbia). Since the Resavska Cave is famous show cave, higher diversity of all phototrophs, not only diatoms is expected because of artificial light, but also due to the presence of the tourists that can introduce different microorganisms from the outside environment.
A total of 24 diatom species from 10 genera were identified. The most frequent and abundant genera are Humidophila (12 species) and Sellaphora (3 species), while others (Cyclotela, Fallacia, Diadesmis, Luticola, Nitzschia, Orthoseira, Simonsenia, Tryblionella) count one to two species. This cave is mostly populated by aerophytic and cosmopolitan species such as Humidophila contenta, Humidophila paracontenta and Humidophila perpusila that were present at the entrance and inside the cave. Beside of Humidophila representatives, species Fallacia insociabilis, Diadesmis biceps, Sellaphora nigri and Sellaphora saugerresii were registered inside the cave in low abundance. Inside the cave, at sampling site with dripping water Cyclotella sp. and Luticola sp. were documented. Entrance of the cave includes ten species which were recorded inside as well, except for the Humidophila aerophila which was found only at the entrance.

AB  - The term bottled water refers to the water that is packaged in a health-correct packaging and that is available on the market for
human consumption. Consumers still have insufficient knowledge of the importance of certain ingredients and their harmful or
beneficial effects on the human body. Nowdays there are many legal acts in the world that regulate the quality of bottled water. In
order to assess the impact of packaging quality on the quality of bottled water, it is necessary to look at the regulation, both in the
field of water and in the field of packaging polymer. The information provided on the declaration is insufficient to see the quality of
the bottled water itself, and there is no indication of the potential toxic elements that can migrate from the packaging into the water.
Although PET is considered as inert material according certain components that are added to PET production can migrate in the
water, that must be regurarly controlled. Declarations of such products must follow the updating and monitoring of potentially toxic
parameters in accordance with European and world regulations. The impact of packaging, transport and storage on the change of
bottled water quality from the aspect of potentially toxic substances has been shown in many studies in the world, however, studies
of this type are rare in our country.

AB  - The presence of biofilms on stone monuments can lead to biodeterioration processes that significantly lower not only the aesthetic value of cultural heritage sites but also cause considerable physical and chemical damage to stone surfaces. In terrestrial environments, cyanobacteria have a significant role in biofilm formation on a variety of natural and artificial stone substrata, including granite, sandstone, limestone, lime mortar, etc. Studies on cyanobacterial diversity and estimation of biodeteriorative activity on stone cultural heritage objects can be very important for conservators and restorers, and cyanobacteria removal from stone monuments is currently a great challenge for conservation science. In that sense, the diversity of terrestrial cyanobacteria was investigated at six localities in Serbia. Samples for cyanobacterial analyses were taken from surface biofilms covering different substrata: granite and lime mortar (The Monument to the Unknown Hero), sandstone (Branko's Bridge, Eiffel's Lock) and carbonate rock (Medieval tombstones from Mramorje and Rastite, Gradac Monastery). A total of 18 cyanobacterial taxa were identified. The highest diversity was found on carbonate rock, followed by sandstone. Cyanobacteria were also recorded on an artificial substratum - lime mortar, while cyanobacteria were not found on granite. All detected cyanobacteria seriously impaired the structural and aesthetic integrity of the studied monuments via mechanical and chemical actions, so their presence must not be overlooked.

AB  - The aim of this study was to assess the effect of substrate type and incubation depth on periphyton that had developed on artificial substrates. Uniform rectangular tiles made out of artificial substrates: glass, ceramic, willow tree and yew tree, were fixed on a floating buoy and deployed at three different depths in a photic zone of the Sava Lake (Belgrade, Serbia). Non-taxonomic attributes in the developed biofilm were estimated week-by-week from the start of the experiment in July, until its end in September 2014. Through assessment of substrate type and depth of incubation effect we concluded that these parameters for the fact influence periphyton development and composition. Glass was preferred by autotrophic component over ceramic and wooden substrates. In general, substrate type effect was diminished by increasing incubation depth. When non-taxonomic parameters are to be used in biomonitoring studies, our results suggest that glass substrate and shallow layer of water column (up to 50 cm) for incubation should be preferred.
