AB  - The discharge of industrial textile waters into water bodies leads to the accumulation of pollutants which are a serious threat to humans and the environment. The development of an efficient adsorbent for the removal of toxic organic dyes from water is of crucial importance. For that reason, this work aimed to elaborate on the potential application of a biosorbent obtained from waste Humulus lupulus stems (Hlup-BA) for the elimination of malachite green, methylene blue, and crystal violet from aqueous solution in batch and fixed-bed column systems. The Hlup-BA was characterized using chemical composition analysis, by determination of particle size distribution, the point of zero charge (pHpzc), SEM, BET, EDS, XRD, and FTIR. Comprehensive analysis of Hlup-BA adsorption efficiency in a batch study showed that at the optimal conditions (e.g. contact time, 120 min; biosorbent dose, 2 g/L; dye concentration, 100 g/L; pH, 8 and temperature, 298 K), even 98.4 %, 98.8 %, and 98.5 % of MG, MB, and CV were removed, respectively. The results showed that the biosorption process followed pseudo-second-order kinetics. The equilibrium data were modeled using Langmuir, Freundlich, Sips, and Dubinnin-Radushkevich biosorption isotherms. High values of Hlup-BA biosorption capacities obtained from Langmuir isotherm were 398.9 mg g−1, 209.8 mg g−1, and 133.2 mg g−1 for MG, MB, and CV, thus proving Hlup-BA as an excellent biosorbent for removal of the tested dyes. The thermodynamic study indicated that the biosorption of these three dyes on Hlup-BA from aqueous solution is an endothermic, spontaneous, and thermodynamically stable process. The proposed mechanism of the biosorption process covers π-π interactions, electrostatic interactions, and hydrogen bonding. Furthermore, the data obtained by modeling in the fixed-bed column were also successfully correlated with the Thomas, Bohart-Adams, and Yoon–Nelson models. The very good fit of the results obtained in this way will greatly contribute to optimizing the pilot-scale operations for future wastewater treatment. Consequently, Hlup-BA can be an effective, cheap, and environmentally friendly biosorbent to eliminate methylene blue, malachite green, and crystal violet dyes from the aqueous solution in batch and column systems.

AB  - Probiotics as the most promising group of microbes have the possibility to synthesize metabolites, that can be used in different industries over the world. In this study, we investigated the probiotic activity of the Lactobacillus reuteri B2, as well as, the exopolysaccharides (EPS) that this strain produced. L. reuteri B2 was isolated from the feces of C57BL/6 mice and assessed on probiotic activity. L. reuteri B2 was identified by 16S rDNA sequencing, in which the cell viability in acidic conditions at pH 2.0 was 64% after 2 h, and in the presents of 0.30% of the bile salts, after 6 h, was 37%. Antimicrobial assay with L. reuteri B2 showed maximum diameters against K. oxytoca J7 (12.5±0.71mm). We further hypothesized if L. reuteri B2 strain in the free form can survive all conditions in the gastrointestinal tract (GIT) then the utilization of the appropriate biomaterials would ameliorate its stability and viability in GIT. L. reuteri B2 was microencapsulated into sodium alginate- (Na-alg) and different content of Na-alg and sodium maleate (SM) beads. Second hypothesis was if a novel EPS, extracted and isolated from L. reuteri B2, that obtain biological activity can be used as biomaterial. Characterization of this EPS enveloped FTIR, NMR, SEM, XRD, TGA/DTG analysis, biological assays, antioxidative activity, cytotoxic assay (MTT), and adhesion assay of L. reuteri B2 to HT29 cells. This EPS obtained a high scavenging effect of 76% at 2mg/mL of EPS in ABTS assay, while in MTT assay showed that did not have a cytotoxic effect.

Increasing demands for energy, food, water, metals, and other natural resources have resulted in resource depletion, environmental pollution, and nature destruction. It is necessary to establish different sustainable approaches to define these effects on the environment. Life Cycle Assessment as an analytical approach can provide a determination of environmental impacts as a consequence of the use of natural resources. The aim of this study is to highlight the significance of life cycle assessment and reveal how it is connected to sustainable issues in the use of natural resources.

AB  - The actual paper analyses the performance of different energy crop biomasses, Miscanthus x giganteus Greef et Deu (EC-1) and Arundo donax L. (EC-2) stems, during slow pyrolysis process monitored by simultaneous TG-DTG-MS techniques, through chemical exergy analysis. In addition to considering the physical and chemical characteristics of given feedstocks for their efficient thermo-chemical conversion into pyrolytic gas, in this study, a theoretical simulation for their implementation use in the gasification process was also performed. The performed thermodynamic study with detailed exergy analysis showed that the large contribution of exergy in syngas components such as CO and H2 originates primarily from cellulose pyrolysis of EC-1, while large exergy contribution in syngas component as CH4 originates from lignin pyrolysis of EC-2. It was founded that the exergy efficiency of syngas for EC-1 equals 19.04%, which is lower than the exergy efficiency of syngas for EC-2 (20.46%), as a result of higher ash content in EC-1. Also, it was reported that higher carbon (C) and hydrogen (H) contents present in the EC-2 sample generate higher gaseous energy and exergy values, i.e. the increment of exergy efficiency of syngas, by both approaches (pyrolysis and gasification exergy analysis), but results in a lower biomass chemical exergy (18.28 MJ kg−1). The methodology applied to the gasification process was shown a higher exergy efficiency for EC-2 (∼36 – 42%) than for EC-1 (∼33 – 39%), dependant on the equivalence ratio (ER).

AB  - This work provides insight into possibilities of maximum utilization of C3-C4 energy crops for thermo-chemical conversion (slow pyrolysis) into high value biochemicals, platform chemicals, drop-in fuels and combustible gases, using coupled kinetic and thermodynamic analyses. In order to examine the kinetics of decomposition of lignocellulosic components, model-free and model-based methods faded from thermal analysis data were used. Thermodynamic compensation was used for explicatory of entropy controlled process, where conformational changes and chemical exchange directly affect the type and distribution of obtained pyrolytic products. It was shown that external variable (i.e. the heating rate/temperature) does not change either an entire reaction mechanism (mechanistic nature of MG and AD pyrolyses) or transition state, but it changes activation enthalpy and activation entropy which lead to differences in terms of heat energy consumption, pyrolysis favorability and thus rates of generation of activated complex among feedstocks. To investigate the interplay of catalysts (present in feedstocks as minerals) and reactants, selective energy transfer (SET) model was applied. The model showed an activity of catalyst with different outputs towards two reactants, lignin part of the structure in MG and 1,8-cineole in AD. It was shown that AD is more convenient for thermal conversion than MG, regarding to lower transformation energy requirement, higher reactivity, as well as much faster accumulation of products.

AB  - Nowadays, exopolysaccharides (EPS) produced from bacterial cells are manufactured for their use in different industries in the world, mainly in the food, pharmaceutical, and wastewater industries. The characteristics of EPS, such as being biodegradable, safe, high adsorption capacity, and reusable, make them significant and potential applications in the purification of contaminated water of heavy metals. In this study, the possible application in biosorption Ni2+ ions from contaminated water was assessed using this exopolysaccharide as a biosorbent. The new exopolysaccharide from the bacterial strain K. oxytoca J7 was extracted, isolated, and characterized using SEM, FTIR, XRD, TGA/DTG, and MALDI-TOF MS analysis. Likewise, the cytotoxic activity was performed for EPS from K. oxytoca J7 strain. The aim of this study was to investigate the possible application of non-toxic exopolysaccharide in the purification of contaminated water by removing Ni2+ ions. The results obtained from the biosorption study showed that the Langmuir model is well suited to describe the adsorption process of Ni2+ ions by EPS from K. oxytoca J7, with a maximum adsorption capacity of 269.97 mg g–1. The importance of this study is the possible use of natural nontoxic exopolysaccharide extracted from the pathogen microorganism, K. oxytoca J7, for the removal of Ni2+ ions from the contaminated water.

The results obtained from the biosorption study showed that the Langmuir model is well suited to describe the adsorption process of Ni2+ ions by EPS from K. oxytoca J7, with a maximum adsorption capacity of 269.97 mg g–1. The importance of this study is the possible use of natural nontoxic exopolysaccharide extracted from the pathogen microorganism, K. oxytoca J7, for the removal of Ni2+ ions from the contaminated water.",

AB  - In this study, the structure, morphology and composition of the synthesized magnetite/3D-printed wollastonite (3D_W/M) composite were characterized, and its adsorption performance with respect to As(V) and Cr(VI) were studied. Magnetite (MG) modified 3D printed wollastonite was obtained by two step procedure: modification of 3D_W with 3-aminoproylsilane (APTES) followed by controlled magnetite (MG) deposition to obtain 3D_W/M adsorbent. The structure/properties of 3D_W/M were confirmed by applying FTIR, XRD, TGD/DTA, and SEM analysis. The adsorption properties of hybrid adsorbents were carried out for As(V) and Cr(VI) removal-one relative to the initial pH value, the adsorbent mass, the temperature, and the adsorption time. Time-dependent adsorption study was best described by pseudo-second order equation, while Weber Morris analysis showed that intraparticle diffusion controled diffusional transport. Similar activation energy, 17.44 and 14.49 kJ•mol-1 for adsorption As(V) and Cr(VI) on 3D_W/M, respectively, indicated main contribution of physical adsorption. Determination of adsorption parameters was performed by applying different adsorption isotherm models, and the best fit was obtained using Freundlich model. The adsorption capacity of 24.16 and 29.6 mg g-1 for As(V) and Cr(VI) at 2o C, Co = 5.5 and 5.3 mg L-1, respectively, were obtained. Thermodynamic study indicated favourable process at a higher temperature. Preliminary fixed-bed column study and results fitting with Bohart-Adams, Yoon-Nelson, Thomas, and Modified dose-response model showed good agreement with results from the batch study.

AB  - As one of the most promising groups of microbes, lactic acid bacteria (LAB) can synthesize metabolites that can be used in different industries over the world, mainly in the pharmaceutical, food, and dairy industries. In this study, a novel exopolysaccharide was extracted and isolated from the probiotic strain Lactobacillus reuteri B2, and assessed on biological activity and its possible application as a biosorbent for the removal of Ni2+ ions from contaminated water. New exopolysaccharide was characterized using FTIR, SEM, XRD, NMR, MALDI-TOF MS, and TGA/DTG analysis. Biological assays included antioxidative activity, cytotoxic assay, and adhesion assay of L. reuteri B2 to HT29 cells. Our hypothesis was that if this exopolysaccharide is nontoxic, it can be used as a novel biomaterial for the possible application of the removal of Ni2+ ions from contaminated water. The scavenging effect of nontoxic exopolysaccharide was 76% at 2 mg/mL using ABTS assay, in biological assays, while the removal efficiency of nickel from the aqueous solution was 92.96% in biosorption study. According to these results, this exopolysaccharide can be considered a very promising biomaterial for potential application in different industries, from pharmacy to wastewater treatments.

This concern stems from the fact that nickel is biodegradable, highly toxic, and can potentially cause numerous adverse effects on human health. In this work, the biosorption of nickel ions at different contact times was investigated using hop biomass waste. The high correlation coefficient value of 0.999 indicates that the adsorption kinetics follows a pseudo-second-order model.

AB  - Lactic acid bacteria synthesize metabolites that can be used in pharmaceutical, food, water, and dairy industries. Hence, in this study, a novel exopolysaccharide was extracted and isolated from the probiotic strain L. reuteri B2, assessed on possible application as a biosorbent for removal of heavy metals from the contaminated water. Novel exopolysaccharide was characterized using SEM, and TGA/DTG analysis. Our hypothesis was that if this EPS can be used as potentinal biomaterial, than its application for nickel removal from the contaminated water can be performed. After biosorption experiments, the removal efficiency of Ni2+ from the aqueous solution was 92.96%. According to these results, this exopolysaccharide can be considered as a very promising biomaterial for application in different industries, from pharmacy to treatments of contaminted water

abstract = "Lactic acid bacteria synthesize metabolites that can be used in pharmaceutical, food, water, and dairy industries. Hence, in this study, a novel exopolysaccharide was extracted and isolated from the probiotic strain L. reuteri B2, assessed on possible application as a biosorbent for removal of heavy metals from the contaminated water. Novel exopolysaccharide was characterized using SEM, and TGA/DTG analysis. Our hypothesis was that if this EPS can be used as potentinal biomaterial, than its application for nickel removal from the contaminated water can be performed. After biosorption experiments, the removal efficiency of Ni2+ from the aqueous solution was 92.96%. According to these results, this exopolysaccharide can be considered as a very promising biomaterial for application in different industries, from pharmacy to treatments of contaminted water, Bakterije mlečne kiseline sintetišu metabolite koji se mogu koristiti u farmaceutskoj, prehrambenoj,

AB  - The very serious problem in developing countries has become the presence of the arsenic
contamination in the water for the public health. Still, millions of people in their daily lives are
highly dependent on groundwater containing high levels of arsenic, as well as, in drinking water,
which causes excessive exposure to this toxic element, due to the high cost and lack of watertreatment infrastructures. The maximal allowed concentration (MAC) for As(V) in water
decreased from 50 to 10 μg/l, by considering the harmful effects of arsenic on the environment
and human health. In order to achieve the established rigorous requirements, it is necessary to
develop new materials and design new forms of adsorbents that can reduce the concentration of
arsenic in drinking water. Therefore, in this study, the target was to synthesize magnetite/3Dprinted wollastonite hybrid sorbent that was used to remove As(V) from aqueous solutions. 3Dprinted wollastonite was obtained using the 3D-printing technique from
methylhydrocyclosiloxane and calcium carbonate as precursors. Synthesis of adsorption
material was carried out by depositing magnetite from an iron(II)-sulfate solution by potassium
hydroxide on 3D-printed wollastonite. Characterization of the obtained material was performed
using FTIR and SEM. An investigation of the sorption properties of hybrid adsorbents was
carried out for As(V) removal - one relative to the starting pH value of the solution, the
adsorbent mass and the temperature and the adsorption time. Determination of adsorption
parameters was performed by applying Langmuir, Freundlich and Dubinin-Radushkevich
equations. Determination of kinetics and adhesion parameters at three different temperatures
enabled the calculation of thermodynamic and activation parameters of the adsorption process,
which contributed to a better understanding of the adsorption mechanism. Also, based on the
results, it was noticed that the highest adsorption capacity of the mentioned material for arsenic
ions at a temperature of 45 °C. The compact filter presented in this report should serve well as a
small-scale water-purification unit that can be easily carried to any site having water
contaminated with arsenic

AB  - Thiocarbohydrazones and their derivatives represent a class of compounds with various biological and pharmaceutical properties, including strong antioxidant, antitubercular, antimicrobial, and anticancer activity [1]. Therefore, in this work, new asymmetrically substituted bis-(thiocarbohydrazones) (TCHs) bearing 2-pyridine and quinoline moiety were synthesized and showed promising in vitro antioxidant and anticancer activity (Figure1). The results suggest that antioxidant activity of TCH depends on the structure, substituent type and antioxidant assay used. The maximum antioxidant activity in DPPH and CUPRAC tests was observed for compound with 8-quinolyl and 8-hydroxy-2quinolyl moiety. Additionally, anticancer assays revealed that compounds interfere with cancer cell mobility at concentrations below 10 μM, and exert low toxicity toward healthy human HaCaT fibroblasts. The results of this study represent a good foundation for further research and development of novel iminopyridines with improved antioxidant and anticancer activity.

AB  - Aquatic pollution caused by pesticides as a consequence through run-off, leaching, and subsurface drainage, may pose a serious health hazard for living being and ecosystems due to
pesticides persistent nature and bio-magnification. Since most organic pesticides are nondegradable and carcinogenic, they represent a potent category of water contaminants. The aim
of the presented work was to develope functional biodegradable membranes which could be used
as an efficient adsorbent for the removal of pesticides (difenoconazole and thiophanate-methyl)
from aquatic solutions. The bio-renewable membranes (Cell-El and Cell-El-Ta) based on epoxyamino reactivity of the Cellulose fibres (Cell) modified with diethylenetriamine (Cell‒Deta), (3-
Glycidyloxypropyl)trimethoxysilane (Cell-Glymo), Lignin modified with epichlorohydrine (El)
and Tannic acid (Ta), as an additional crosslinker, were produced by optimized methods through
the application of novel approaches. The membrane preparation was conducted at the
appropriate molar ratio of functional groups designed to provide numbers of residual
functionalities effective for pesticide removal. The membranes were characterized by FourierTransform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). FTIR
spectral analysis was used to identify the characteristic functional groups of produced
membranes and spectral pattern change as a result of the formation of coordination complexes
of pesticides with surface functionalities. Controlled modification of Cell fibre and subsequent
production of Cell-El and Cell-El-Ta membrane causes change fibres surface and material
morphology, and SEM analysis proved successful modification and membrane production with
formation a large number of fibres interconnections. The effects of contact time, temperature,
and initial concentration of pesticides on adsorption were studied in a batch system. The
Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich (D-R) isotherm models were used to
evaluate the adsorption process, and to predict the adsorption capacity of the adsorbents. The
experimental results were best fitted with the Langmuir isotherm model. The calculated
capacities: 32.2, 69.3, 45.1 and 83.2 mg g-1 for difenoconazole and thiophanate-methyl using
Cell-El and Cell-El-Ta, respectively, were obtained from Langmuir model fitting at 25oC. The
thermodynamic parameters indicated spontaneous and low endothermic processes. The present
study demonstrates that prepared membranes could be an effective and low-cost adsorbent to
prevent contamination of water and consequently help minimize the environmental impact
caused by the pesticides.

pesticides persistent nature and bio-magnification. Since most organic pesticides are nondegradable and carcinogenic, they represent a potent category of water contaminants. The aim
of the presented work was to develope functional biodegradable membranes which could be used
as an efficient adsorbent for the removal of pesticides (difenoconazole and thiophanate-methyl)
from aquatic solutions. The bio-renewable membranes (Cell-El and Cell-El-Ta) based on epoxyamino reactivity of the Cellulose fibres (Cell) modified with diethylenetriamine (Cell‒Deta), (3-
Glycidyloxypropyl)trimethoxysilane (Cell-Glymo), Lignin modified with epichlorohydrine (El)
and Tannic acid (Ta), as an additional crosslinker, were produced by optimized methods through
the application of novel approaches. The membrane preparation was conducted at the
appropriate molar ratio of functional groups designed to provide numbers of residual
functionalities effective for pesticide removal. The membranes were characterized by FourierTransform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). FTIR
spectral analysis was used to identify the characteristic functional groups of produced
membranes and spectral pattern change as a result of the formation of coordination complexes
of pesticides with surface functionalities. Controlled modification of Cell fibre and subsequent
production of Cell-El and Cell-El-Ta membrane causes change fibres surface and material
morphology, and SEM analysis proved successful modification and membrane production with
formation a large number of fibres interconnections. The effects of contact time, temperature,
and initial concentration of pesticides on adsorption were studied in a batch system. The
Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich (D-R) isotherm models were used to
evaluate the adsorption process, and to predict the adsorption capacity of the adsorbents. The
experimental results were best fitted with the Langmuir isotherm model. The calculated
capacities: 32.2, 69.3, 45.1 and 83.2 mg g-1 for difenoconazole and thiophanate-methyl using
Cell-El and Cell-El-Ta, respectively, were obtained from Langmuir model fitting at 25oC. The
thermodynamic parameters indicated spontaneous and low endothermic processes. The present
study demonstrates that prepared membranes could be an effective and low-cost adsorbent to
prevent contamination of water and consequently help minimize the environmental impact
caused by the pesticides.",

AB  - In this study, Lactobacillus reuteri B2was isolated fromthe feces of C57BL/6 mice and assessed on probiotic activity.
L. reuteri B2was identified by 16S rDNA sequencing, which the cell viability in acidic conditions at pH 2.0was
64% after 2 h, and in the presents of 0.30% of the bile salts, after 6 h, was 37%. Antimicrobial assay with L. reuteri B2
showed maximumdiameters against Klebsiela oxytoca J7 (12.5±0.71mm).Wefurther hypothesized if L. reuteri
B2 strain in the free form can survive all conditions in the gastrointestinal tract (GIT) then the utilization of the
appropriate biomaterials would ameliorate its stability and viability in GIT. L. reuteri B2 was microencapsulated
into sodium alginate-(Na-alg) and different content of Na-alg and sodium maleate (SM) beads. Characterization
materials enveloped their thermal characteristics (TGA/DTA analysis) and structure using: scanning electron microscopy
(SEM), FTIR, and particle size distribution. The high survival rate of L. reuteri B2 at lowpH from2.0 to 4.0
and in the presence of the bile salts, at concentrations up to 0.30%, was obtained. L. reuteri B2 showed strong antimicrobial
activity and the best protection microencapsulated with Na-alg + SM in simulated gastric juices
(SGJ).

AB  - As a renewable resource, starch is considered to be fully biodegradable and nonpolluting to the environment but the hygroscopicity of starch is the main disadvantage for wider applicability in the production of a polymer-based material. Hydrophobically modified starch prepared using natural-based plasticizers/modifiers in a first step ([−]-diisopropyl D-tartrate [DiPT], ricinoleic acid [RA] and epoxidized soybean oil [ESO]), and maleated polypropylene (MAPP) in a second step contributed to better compatibility, and thus reinforcing of composites. Tailored processing conditions, structural/morphological properties, hydrophobicity, and water-resistance of the modified starch were established. In addition, the Charpy impact and tensile strength of composites, based on poly(ethylene-co-acrylic acid) (EAA) and modified starches, were determined. Increased tensile strength and Young modulus of the composite using starch-modified with DiPT-MAPP, that is, 3 and 83%, respectively, indicated the possible applicability of obtained materials.

AB  - Energy is the main driver of economic growth and it is of vital significance for the modern socieity survival. Future economic growth is dependent of the long-term availability of energy from the sustainable and ecologicaly accepted sources. Microbial fuel cell (MFC) is a new approach to the wastewater treatment with the simulntanious energy production.
