AB  - In this study, levan from Bacillus licheniformis NS032 was modified in an aqueous medium by octenyl succinic
anhydride (OSA), and the properties of the obtained derivatives were studied. The maximum efficiency in the
synthesis reaction was achieved at 40 ◦C and a polysaccharide slurry concentration of 30 %. Increasing the
reagent concentration (2–10 %) led to an increase in the degree of substitution (0.016–0.048). Structures of
derivatives were confirmed by FTIR and NMR. Scanning electronic microscopy, thermogravimetry, and dynamic
light scattering analyses showed that the derivatives with degrees of substitution of 0.025 and 0.036 retained
levan’s porous structure and thermostability and showed better colloidal stability than the native polysaccharide.
The intrinsic viscosity of derivatives increased upon modification, while the surface tension of the 1 % solution
was lowered to 61 mN/m. Oil-in-water emulsions prepared with sunflower oil (10 % and 20 %) by mechanical
homogenization and 2 and 10 % derivatives in the continuous phase showed mean oil droplet sizes of 106–195
μm, while the distribution curves exhibited bimodal character. The studied derivatives have a good capacity to
stabilize emulsions, as they have a creaming index ranging from 73 % to 94 %. The OSA-modified levans could
have potential applications in new formulations of emulsion-based systems.

AB  - The quest for sustainable biomaterials with excellent biocompatibility and tailorable
properties has put polyhydroxyalkanoates (PHAs) into the research spotlight. However, high production
costs and the lack of bioactivity limit their market penetration. To address this, poly(3-
hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) was combined with a bacterial pigment with strong
anticancer activity, prodigiosin (PG), to obtain functionally enhanced PHBV-based biomaterials. The
samples were produced in the form of films 115.6–118.8  m in thickness using the solvent casting
method. The effects of PG incorporation on the physical properties (morphology, biopolymer crystallinity
and thermal stability) and functionality of the obtained biomaterials were investigated. PG
has acted as a nucleating agent, in turn affecting the degree of crystallinity, thermal stability and
morphology of the films. All samples with PG had a more organized internal structure and higher
melting and degradation temperatures. The calculated degree of crystallinity of the PHBV copolymer
was 53%, while the PG1, PG3 and PG3 films had values of 64.0%, 63.9% and 69.2%, respectively.
Cytotoxicity studies have shown the excellent anticancer activity of films against HCT116 (colon
cancer) cells, thus advancing PHBV biomedical application potential.

AB  - One of the most popular alternative sources of energy are direct methanol fuel cells (DMFCs) with platinum-based catalysts due to their non-toxicity, reduced emissions of hazardous pollutants and high energy density. However, significant challenges of the scientific community related to Pt catalysts are the high cost, depletable resources and formation of poisoning species i.e. CO, during the methanol oxidation reaction. To reduce the amount of expensive Pt and susceptibility of Pt to poisoning species and simultaneously improve its catalytic performance, recent studies are focusing on the synthesis of Pt alloys in which a certain amount of platinum is replaced with less expensive metals such as Ru, Sn, Ni, Cu, Rh and Co. The usage of carbon (Vulcan XC-72R) for catalyst support enables high dispersion of metal, high surface area and good electrical conductivity improving overall performances of DMFCs. In this work, PtZn/C and PtSnZn/C catalysts were synthesized by the microwave-assisted polyol method. The structure and morphology of the catalysts were characterized by transmission electron microscopy (TEM), thermogravimetric (TG) and X-ray diffraction (XRD) analysis. The activity and stability of synthesized catalysts for methanol oxidation in 0.5 M sulfuric acid were investigated. It was demonstrated that the activity of the platinum catalysts was improved thanks to the synergistic effects caused by the addition of different metals, such are bifunctional and electronic effects.

development of an efficient and economical catalyst is a crucial step. Reducing the
diameter of catalyst particles, producing particles with a specific orientation surface,
and alloying noble metals with less expensive metals are possible approaches to
improve catalyst performance. This study will be focused on novel ways for creating
PtSnZn catalysts that are more effective for the anodic reactions in fuel cell such are
methanol, ethanol and formic acid oxidation reactions. PtZn and PtSnZn
nanoparticles were produced using the microwave assisted polyol method and were
supported on high surface area carbon Vulcan XC-72R material. The electrochemical
behavior of synthesized catalysts was investigated utilizing the cyclic voltammetry,
chronoamperometric technique, and electro-oxidation of adsorbed CO. To determine
the catalyst's physicochemical characteristics, X-ray diffraction (XRD), transmission
electron microscopy analysis (TEM), and thermogravimetric analysis (TGA) were
used. High catalytic activity of the PtSnZn/C catalysts was achieved thanks to the
benefits of microwave synthesis and carefully adjusted metal alloying.

and dispersion of nanoparticles. Cyclic voltammetry and electrooxidation of
adsorbed CO were used to investigate the electrochemical behavior of
synthesized catalysts: PtZn/C (90:10); PtZn/C (85:15) and PtZn/C (75:25). It
was found that PtZn/C catalysts have high electrocatalytic performance in
methanol oxidation reactions. In comparison to the corresponding catalyst with
the different Zn loading, it was concluded that PtZn (90:10)/C catalyst had
better activity compared to PtZn/C (85:15) and PtZn/C (75:25) catalysts. The
observed high catalytic activity in the methanol oxidation reaction of

Poređenjem katalizatora sa različitim sadržajem Zn, zaključeno je da PtZn/C (90:10) katalizator ima bolju aktivnost u odnosu na PtZn (85:15) i PtZn (75:25) katalizatore. Uočena visoka katalitička aktivnost sintetisanih katalizatora u reakciji oksidacije metanola može se pripisati veoma efikasnoj mikrotalasnoj sintezi i dobro izbalansiranom dodavanju Zn kao legirajućeg metala sa različitim sadržajem u PtZn/C katalizatorima.

AB  - Polymer electrolyte membrane fuel cells (PEMFCs) are pure electrochemical energy converters that are key components of energy sources for vehicles and for stationary and portable energy suppliers. Searching for a good catalyst for the ethanol oxidation reaction is one of the most significant issues in material science. To increase the economic potential of fuel cell technology, catalyst must be extremely active, stable, and inexpensive. Due to its high catalytic activity, structural and chemical stability, and widespread use in commercial fuel cells, platinum is still the material of choice for making cathodes. Although there is extensive continuing research to reduce the Pt concentration while keeping the high catalytic activity, its high cost remains a barrier to a wider adoption of fuel cell technology.Therefore, the potential for cost reduction lies in the optimization of the catalyst, i.e. obtaining the maximum catalytic efficiency with the lowest possible content of noble metals. The focus of this research will be on novel synthesis techniques for PtSnZn catalysts with better efficiency and durability for the ethanol oxidation reaction. This research demonstrates the potential of studying new PtSnZn catalytic materials as catalysts for the oxidation of ethanol. This study used the microwave assisted polyol technique to create PtZn and PtSnZn nanoparticles supported on high surface area carbon Vulcan XC-72R material. By using cyclic voltammetry, electro-oxidation of adsorbed CO, and the chronoamperometric method, the electrochemical behavior of synthesized catalysts was examined. X-ray diffractometry, transmission electron microscopy analysis and thermogravimetric analysis were applied to obtain the physicochemical properties of the catalyst. The advantages of microwave synthesis and carefully balanced metal alloying in the PtSnZn/C catalysts led to a high catalytic activity of the synthesized catalyst in the ethanol oxidation reaction compared to the Pt/C catalyst.

AB  - This study investigates the effect of surface modification by deposition of electrospun fibers on properties and performance of three different microporous polypropylene/polyethylene (PP/PE) commercial nonwoven membrane supports (Novatexx 2430, 2465 and 2473). Polyamide (nylon 6) nanofiber webs with a small number of defects and fibers of about 100 nanometer diameter were successfully deposited onto a surface of the selected membrane supports. FESEM was used to examine microstructure and morphology of the unmodified substrates and the prepared composite two-layer membranes. DSC was applied to investigate thermal stability and FT-IR analysis to confirm the chemical composition of the studied membranes. Saline water permeability tests of the prepared two-layer composite membranes were carried out. The largest pressure difference was measured for PA nanofiber/Novatexx 2430 sample, which was ascribed to a denser net structure of the membrane support and possibly to the newly formed layer of dissolved salts on the membrane surface.

AB  - This paper examined the degree of sensitization (DOS) to intergranular corrosion (IGC) and the level of electrical conductivity of the welded and non-welded AISI 304 stainless steel to obtain a suitable correlation. The DOS was determined by the double loop electrochemical potentiokinetic reactivation method (DL EPR), while the level of electrical conductivity was measured using a commercial device (non-destructive method). After electrochemical etching in oxalic acid, the microstructure of the specimen surface was analyzed by scanning electron microscopy (SEM). At DOS greater than ~ 0.5%, a clear linear dependence between the electrical conductivity and the value of the DOS was obtained, while there was a higher deviation from linearity for lower DOS values. The mentioned correlations were discussed in the sense of the precipitation kinetics of the Cr-carbide and the formation of Cr-depleted areas of different levels near the grain boundaries. Cr-depleted areas during anodic polarization measurements show lower resistance to pit formation. The presence of Cr-depleted areas in the vicinity of grain boundaries and the reduction of carbon content in the austenite crystal lattice increases the electrical conductivity of the stainless steel.

AB  - This work highlights the potential for the synthesis of new PtSnZn catalysts with enhanced efficiency and durability for methanol oxidation reaction (MOR) in low-temperature fuel cells. In this research, PtZn and PtSnZn nanoparticles deposited on high surface area Vulcan XC-72R Carbon support were created by a microwave-assisted polyol method. The electrochemical performances of synthesized catalysts were analyzed by cyclic voltammetry and by the electrooxidation of adsorbed CO and the chronoamperometric method. The physicochemical properties of obtained catalysts were characterized by transmission electron microscopy (TEM), thermogravimetric (TGA) analysis, energy dispersive spectroscopy (EDS) and by X-ray diffraction (XRD). The obtained findings showed the successful synthesis of platinum-based catalysts. It was established that PtSnZn/C and PtZn/C catalysts have high electrocatalytic performance in methanol oxidation reactions. Catalysts stability tests were obtained by chronoamperometry. Stability tests also confirmed decreased poisoning and indicated improved stability and better tolerance to CO-like intermediate species. According to activity and stability measurements, the PtSnZn/C catalyst possesses the best electrochemical properties for the methanol oxidation reaction. The observed great electrocatalytic activity in the methanol oxidation reaction of synthesized catalysts can be attributed to the beneficial effects of microwave synthesis and the well-balanced addition of alloying metals in PtSnZn/C catalysts.

AB  - Bacterial nanocellulose, BNC, has emerged as a new class of nanomaterials recognized as renewable, biodegradable, biocompatible and material for versatile applications. BNC also proved as a perfect support matrix for metallic nanoparticle synthesis and appeared as suitable alternative for widely used carbon based materials. Following the idea to replace commonly used carbon based materials for platinum supports with the green and sustainable one, BNC appeared as an excellent candidate. Herein, microwave assisted synthesis has been reported for the first time for platinum nanoparticles supported on BNC as green material. Bacterial nanocelullose-platinum catalyst, Pt/BNC, was investigated by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), atomic force microscopy (AFM), X-ray diffractometry (XRD) and transmission-electron microscopy (TEM) analysis. The obtained results confirmed successful synthesis of new Pt-based catalyst. It was found that Pt/BNC catalyst has high electrocatalytic performance in methanol oxidation reaction. Green/sustainable catalytic system is highly desirable and provided by the elegant microwave assisted synthesis of Pt/BNC will pave the way for a larger scale application and expedite the market penetration of such fuel cells.

AB  - The main objective of this work was to prepare new platinum supported catalyst on BNC/PVA composite as nanoparticles carrier, designed for electrocatalytic applications. For that purpose, BNC/Pt suspension was mixed with 1 wt% PVA solution and BNC/PVA/Pt catalyst in the form of film was successfully synthesized. The structure and thermal properties of catalyst were characterized by ATR-FTIR and TG analysis, respectively, while its crystallinity was investigated 
by XRD analysis. Electrocatalytic potential of BNC/PVA/Pt catalyst was tested in methanol 
oxidation reaction. Remarkable catalytic activity of new Pt based catalyst was confirmed. The 
obtained results for catalyst activity was comparable to those obtained for preferentially used 
carbon based Pt supports pointing that BNC based composited can be considered as great 
substitution of carbon based materials with the green one.

AB  - Microstructure, phase transitions and thermal properties including thermal diffusivity and thermal conductivity of four Ag–Ge alloys with 20, 40, 60 and 80 at % of Ge were experimentally investigated in this study. Observation and analysis of the alloy microstructures and morphologies of (Ge) phase in the hypereutectic alloys were carried out using optical microscopy and scanning electron microscopy with energy-dispersive X-ray spectrometry (SEM–EDS). Phase transitions of the alloys were studied using differential scanning calorimetry (DSC). Experimentally determined temperature of the eutectic reaction was 650.9 °C. The xenon flash method was used for thermal diffusivity measurements in the temperature range from 25 to 400 °C. Based on the measured values of thermal diffusivity, thermal conductivity of the solid Ag–Ge alloys was determined. It was found that both thermal diffusivity and thermal conductivity show a minimum at 20 at % Ge which is close to the eutectic composition. The obtained results were compared with the results of thermodynamic calculation and literature data, and a close agreement was observed.

AB  - Thermal transport properties of solid Bi-Cu alloys have been investigated over a wide composition range and temperature range ranging from 25 to 250 °C. The flash method was used to determine thermal diffusivity. Thermal diffusivity was discovered to decrease continuously with increasing temperature and bismuth content. The indirect Archimedean method was used to determine the density of the Bi-Cu alloys at 25 °C. The obtained results show that the density of the studied alloys decreases slightly as the copper content increases. Thermal conductivity of the alloys was calculated using measured diffusivity, density, and a calculated specific heat capacity. The thermal conductivity of the studied Bi-Cu alloys decreases with increasing temperature and bismuth content, similar to thermal diffusivity. SEM with energy dispersive X-ray spectrometry (EDS) and differential scanning calorimetry (DSC) were used to examine the microstructure and melting behavior of Bi-Cu alloys, respectively. The eutectic temperature was measured to be 269.9±0.1 °C, and the measured phase transition temperatures and heat effects were compared to thermodynamic calculations using the CALPHAD method.

AB  - Catalysts support is essential for nanostructured noble metal catalysts activity and stability since that interaction between the metal particle and the support can affect metal particle size and dispersion. Over the last few decades, the most popular catalysts supports are carbon based materials: Vulcan XC-72 carbon black (CB), multi-walled carbon nanotubes (MWCNTs) and graphene. However, their cost-effective production remains a challenge since most of these materials are obtained by pyrolysis of coal or petroleum. Not less negligible is their negative impact on the environment during synthesis because these processes include release of carbon dioxide and other harmful organic products into the atmosphere. Applications of bacterial nanocelluloses as a catalyst support has attracted a great attention since it can be easily synthesized and is an inexpensive, biodegradable, sustainable and green material. Bacterial nanocellulose (BNC) was produced utilizing the Komagataeibacter medellinensis ID13488 strain. Stable Pt nanoparticles supported on BNC (Pt/BNC) have been synthetized from a precursor solution of H2PtCl6 by microwave assisted polyol procedure. Catalytic activity was tested for methanol oxidation reaction in sulfuric acid solution. The Fourier transform infrared spectroscopy was used to confirm the structure of bacterial nanocellulose as well as after synthesis of Pt-BNC catalyst. Coupled differential scanning calorimetry (DSC) / thermogravimetric (TG) analysis revealed no loss of platinum during synthesis process. XRD analysis showed characteristic peaks for fcc crystalline structure of Pt/BNC and particle size of 1,7 nm. The activity of the Pt/BNC, catalyst for methanol oxidation was evaluated from potentiodynamic measurements in 0.5 M H2SO4 + 0.5 M CH3OH solution. The results obtained indicate enhanced catalytic activities for methanol oxidation reaction.
AB  - Podloge katalizatora imaju veoma važnu ulogu tokom sinteze katalizatora sa plemenitim metalima obzirom da od njihove interakcije sa metalom zavisi veličina čestica i njihova disperzija tokom procesa sinteze. Tokom poslednjih nekoliko decenija kao najčešće korišćene podloge za platinske katalizatore su korišćene podloge na bazi uglljenika: ugalj razvijene površine (Vulcan XC), ugljenične nanotube ili grafen. Međutim, proces dobijanja ovih materijala ima visoke cene zbog toga što se za njihovo dobijanje koriste procesi pirolize uglja ili nafte. Ništa manje zanemarljiv je i negativan uticaj ovih procesa na okolinu pošto procesi sinteze uključuju oslobađanje ugljen dioksida i drugih štetnih materija u atmosferu. Primena bakterijskih nanoceluloza kao nosača katalizatora privukla je veliku pažnju jer se mogu lako sintetizovati i predstavljaju jeftin, biorazgradiv, održiv i zeleni materijal. Bakterijska nanoceluloza (BNC) proizvedena je upotrebom soja Komagataeibacter medellinensis ID13488.

AB  - Phase diagram of the Bi-Ce-Ge ternary system has been investigated experimentally and thermodynamically extrapolated by using Pandat software. Experimental results were obtained using differential thermal analysis (DTA), scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), and X-ray powder diffraction (XRD) methods. Examined ternary samples belong to two isothermal sections at 400 and 600 °C as well as three vertical sections Bi-CuGe, Cu-BiGe, and Ge-BiCu. No ternary compound has been detected in the equilibrated samples from the selected isothermal sections. Based on the presented experimental data and available literature data, description of the ternary system has been developed. A reasonable agreement between the experimental data and the calculated phase equilibria was obtained. As an example, ternary Cu80Bi10Ge10 alloy was selected for solidification simulations according to Scheil and Lever Rule assumptions as well as for simulation of the total fraction of each solid at different temperatures, latent heat, and total heat.

AB  - Microstructure and thermal properties of slowly cooled Sn–10% Ag and Sn–20% Ag alloys were experimentally investigated in this study. It was found that microstructure of the studied alloys is composed of large, plate-like grains of Ag3Sn intermetallic phase in the Sn-rich eutectic matrix. Phase transition temperatures and corresponding heat effects were experimentally determined and compared with the results of thermodynamic and phase equilibria calculations using the CALPHAD (CALculation of PHAse Diagrams) method and optimized thermodynamic parameters from literature. The xenon flash method was employed for the measurements of thermal diffusivity and determination of thermal conductivity in the temperature range from 25 to 150 °C. The results show that the thermal diffusivity and thermal conductivity gradually decrease with increasing temperature. The determined values of thermal conductivities of the investigated alloys are very close to each other and only slightly higher than that of pure tin. The contributions of electrons and phonons to the thermal conductivity of the studied alloys at room temperature were determined using the Wiedemann-Franz law and the obtained values of the thermal and electrical conductivities. The percentage contributions of the phonon component to the thermal conductivity for Sn–10% Ag and Sn–20% Ag alloys at 25 °C were found to be 20.5% and 28.9%, respectively.

AB  - Due to the wide application of systems based on germanium ternary Bi-Ga-Ge and Bi-Ge-Zn systems were experimentally tested in this study. Used experimental techniques were scanning electron microscope with energy dispersive spectroscopy (SEM-EDS), x-ray diffraction (XRD) and differential thermal analysis (DTA). Three groups of samples were prepared and tested. Alloys were from two isothermal sections at 100 and 300 °C and three vertical sections. Obtained results of experimental tests were compared with predicted phase diagrams. Comparison of EDS and DTA results with calculated phase diagrams of the ternary Bi-Ga-Ge system results in good agreement. While for Bi-Ge-Zn was necessary to introduce new ternary parameters. Introduced ternary parameters were based on experimental results from this study. The thermodynamic descriptions of the ternary Bi-Ga-Ge and Bi-Ge-Zn systems have been developed by using CALPHAD method. Reasonable agreement between experimental data and the calculated phase diagrams has been reached for both ternary Bi-Ga-Ge and Bi-Ge-Zn systems. The liquid projection and invariant equilibria have been calculated by using obtained thermodynamic parameters.

AB  - Thermal properties, including melting temperature, latent heat of melting, specific heat capacity and thermal conductivity, of a low-melting In–Sn–Zn eutectic alloy were investigated in this work. The In–Sn–Zn eutectic alloy with nominal composition 52.7In-44.9Sn-2.4Zn (at.%) was prepared by the melting of pure metals under an argon atmosphere. The conducted assessment consisted of both theoretical and experimental approaches. Differential scanning calorimetry (DSC) was used for the measurement of melting temperature and latent heat, and the obtained results were compared with the results of thermodynamic calculations. The measured melting temperature and the latent heat of melting for the In–Sn–Zn eutectic alloy are 106.5±0.1 °C and 28.3±0.1 Jg-1, respectively. Thermal diffusivity and thermal conductivity of the In–Sn–Zn eutectic alloy were studied by the xenon-flash method. The determined thermal conductivity of the investigated eutectic alloy at 25 °C is 42.2±3.4 Wm-1K-1. Apart from providing insight into the possibility for application of the investigated alloy as the metallic phase-change material, the obtained values of thermal properties can also be utilized as input parameters for various simulation processes such as casting and soldering.

AB  - Alloys based on Sn and Bi are considered to be one of the best soft lead-free solders due to their low melting temperature and low price. In addition, Bi-Sn alloy with a eutectic composition represents a promising candidate as a metallic phase change material (PCM) for use in the field of  thermal energy storage (TES). The accurate knowledge of microstructural and thermophysical properties such as the latent heat of melting, thermal conductivity, specific heat capacity is of crucial importance for PCM selection. Thus, the aim of the current study has been to determine the  microstructure, latent heat of melting and thermal conductivity of a eutectic alloy from the binary Bi-Sn system.

AB  - Low-melting alloys, based on bismuth and indium, have found commercial use in soldering, safety devices, coatings, and bonding applications. In this respect, the accurate knowledge  of  their  thermal  properties  such  as  melting  and  solidification  temperatures, latent heat of melting, supercooling tendency, etc. is of large importance. In the present research,   low-melting   alloy   with   nominal   composition   Bi40In40Pb20(at.   %)   was investigated by means of scanning electron microscopy(SEM) with energy dispersive X-ray spectrometry (EDS) and by differential scanning calorimetry (DSC). Microstructural and chemical (SEM-EDS) analysis has revealed the existence of two coexisting phases in the  prepared  alloy,  which  was  identified  as  BiInand  (Pb).  Melting  and  solidification temperatures  and  the  related  heat  effects  were  measured  by  the  DSC  technique.  The solidus temperature obtained from the DSC heating curves was 76.3 °C and the solidus temperature  obtained  from  the  corresponding  DSC  cooling  runs  was  61.2  °C.  The experimentally  obtained  results  were  compared  with  the  results  of  thermodynamic calculation according to CALPHAD (calculation of phase diagram) approach, and a close agreement was noticed.

AB  - This study presents preparation and characterization of ethyl cellulose based nanocomposites. Successful use of simple solvent casting technique provided nanocomposites with high loads of barium ferrite magnetic nanopowder in the polymer matrix, promising significant improvement of mechanical properties. Investigation of morphology revealed formation of agglomerates that are still on nanoscopic level. Nanocomposite thin films with a higher content of the magnetic powder showed substantial enhancement of break strength, elongation and microhardness compared to the pure ethyl cellulose, which was the primary aim of this research.
AB  - Ова студија представља припрему и карактеризацију нанокомпозита на бази етил целулозе. Успешна употреба једноставне технике изливања обезбедила је нанокомпозите са великим уделом магнетног нанопраха баријум ферита у полимерној матрици, обећавајући значајно побољшање механичких својстава. Истраживањем морфологије откривено је формирање агломерата који су и даље на наноскопском нивоу. Нанокомпозитни танки филмови са већим садржајем магнетног праха показали су значајно повећање прекидне чврстоће, издужења и микротврдоће у поређењу са чистом етил целулозом, што је био главни циљ овог истраживања.

AB  - Petrochemical plastics are generally recalcitrant to microbial degradation and accumulate in the environment. Biodegradable polymers obtained synthetically like poly(ε-caprolactone) (PCL) or polyhydroxyalkanoates (PHA), obtained biotechnologically, have shown great potential as a replacement for petroleum-based plastics. Nevertheless, their biodegradation and environmental faith have been less examined. In this study, thin films of PCL (200 μm) and medium chain length PHA (mcl-PHA, 70 M fraction of 3-hydroxyoctanoate and 30 M fraction of 3-hydroxydecanoate, 600 μm) were exposed to total protein preparations (extracellular proteins combined with a crude cell extract) of soil isolates Pseudomonas chlororaphis B-561 and Streptomyces sp. BV315 that had been grown on waste cooking oil as a sole carbon source. Biodegradation potential of two polyesters was evaluated in buffer with total protein preparations and in a laboratory compost model system augmented with selected bacteria. Overall, PCL showed better biodegradation properties in comparison to mcl-PHA. Both materials showed surface erosion after 4-weeks of exposure to total protein preparations of both strains, with a moderate weight loss of 1.3% when P. chlororaphis B-561 was utilized. In laboratory compost model system PCL and mcl-PHA showed significant weight loss ranging from 13 to 17% when Streptomyces sp. BV315 culture was used. Similar weight loss of PCL and mcl-PHA was achieved for 4 and 8 weeks, respectively indicating slower degradation of mcl-PHA. Growth on waste cooking oil as a sole carbon source increased the potential of both tested strains to degrade PCL and mcl-PHA, making them good candidates for augmentation of compost cultures in waste management of both waste cooking oils and biodegradable polymers.
