AB  - A series of novel polyurethane network/organoclay nanocomposites (PUN-NCs) with different soft segment contents (30–60 wt%) was prepared by in situ polymerization in solution and characterized. PU network (PUN) was made from poly(dimethylsiloxane)-based macrodiol as the soft segment and 4,4′-methylenediphenyldiisocyanate and hyperbranched polyester of the third pseudo generation as the hard segment. Nanocomposites were obtained by dispersion of organically modified montmorillonite (Cloisite 30B) nanofiller (0.5 wt%). The influence of the soft segment content on the functional properties of PUN-NCs was studied by Fourier transform infrared (FTIR), small-angle and near wide-angle X-ray scattering (SWAXS), thermogravimetric analysis (TGA), dynamic mechanical thermal analyses (DMTA), differential scanning calorimetry (DSC), nanoindentation, atomic force microscopy (AFM), scanning electron microscopy (SEM), and swelling behavior, water absorption and contact angle measurements. The biodegradation process was evaluated using mixed cultures of microorganisms that originated from soil. Mechanically strong PUN-NC materials in the form of films were obtained, pointing to good dispersion and the existence of exfoliated morphology of Cloisite 30B within the PUN matrix, and the nanocomposites with the abovementioned characteristics were obtained as a function of the soft segment content. The decrease of the soft segment content induced a higher degree of phase separated microstructure, increase of Young's modulus, hardness, plasticity, storage modulus, glass transition temperature, surface free energy and swelling ability in tetrahydrofuran, but at the same time, it is responsible for the decrease of crosslinking density and hydrophobicity of PUN-NCs. By choosing adequate soft segment content, the prepared materials can potentially be designed for coating applications, such as top coating materials in environmental conditions.

AB  - Persistent organic pollutants (POPs) are lipophilic, constant and bioaccumulative toxic compounds. In general, they are considered resistant to biological, photolytic, and chemical degradation with polychlorinated biphenyls (PCBs) belonging to these chemicals. PCBs were never produced in Serbia, but they were imported and mainly used in electrical equipment, transformers, and capacitors. Our study aimed to analyse sequential multi-stage aerobic/anaerobic microbial biodegradation of PCBs present in the river sediment from the area known for long-term pollution with these chemicals. The study with an autochthonous natural microbial community (NMC model system) and NMC augmented with allochthonous hydrocarbon-degrading (AHD) microorganisms (isolated from location contaminated with petroleum products) (NMC-AHD model system) was performed in order to estimate the potential of these microorganisms for possible use in future bioremediation treatment of these sites. The laboratory biodegradation study lasted 70 days, after which an overall >33 % reduction in the concentration of total PCBs was observed. This study confirmed the strong potential of the NMC for the reduction of the level of PCBs in the river sediment under alternating multi-stage aerobic/anaerobic conditions.

AB  - The first series of polyurethane network nanocomposites (PUNN) was prepared by in situ polymerization [1,2] from poly(dimethylsiloxane)-based prepolymer as the soft segment and 4,4’-methylene diphenyldiisocyanate and hyperbranched polyester of the third pseudo generation as the hard segment, in the presence of organically modified montmorillonite nanofiller (Cloisite 30B; 0.5 wt.%). The second series of pure polyurethane networks (PUN) without organoclay was also prepared. The composition of prepared materials in both series was varied through variation of soft segment content from 30 to 60 wt.%. Biodegradability of prepared materials was measured using mixed cultures of microorganisms that originated from soil. This test used soil bacteria and fungi to assess the impact of the environment on polymer compounds. This test is intended to determine which polymer compositions are best suited for coating other materials that must endure lengthy exposure to harsh environmental conditions while retaining their principal functionalities. The biodegradation test was performed under aerobic conditions in the dark condition and in a thermostat at 28 °C. Bacterial and fungal mixed cultures were alternated monthly. After 3 and 6 months of the test, the materials were washed with water, dried in a vacuum oven to constant weight, and used for gravimetric measurements of weight loss. The prepared materials before and after biodegradation test were characterized by FTIR spectroscopy. The results showed that pure PUNs (18.35-18.66 wt.% after six months) possess the highest weight loss as compared to PUNNs (from 7.53 to 14.78 wt.% after six months) after incubation of up to six months. PUNN films had lower biodegradation degree as compared the pure PUN films. Biodegradability was lower for materials with lower soft segment content. In FTIR spectra of PUNN after biodegradation differences were noted at approximately 1700-1735 and 3324 cm-1. The structures contributing to strong hydrogen bonds were partially destroyed during the biodegradation process. The results showed that PUNN with 40 wt.% of soft segment (PUNN-40) is the most resistance material to biodegradation. The reason was probably due to more hydrogen bonding between the polymer and Cloisite 30B organoclay and its better mechanical properties of PUNN-40 sample as compared to other prepared PUNN materials. The obtained materials are good candidate as top coating materials exposed to the environmental conditions.

AB  - Copper is one of the leading metal pollutants in the water, which can cause adverse effects when present in high concentrations. The Daphnia magna is a model organism usually used for the determination of ecotoxicological effects of various compounds since it is highly sensitive to toxic compounds [1]. The aim of this work was to investigate the potential application of microbial extracellular polysaccharides (EPS), levan and pullulan, as agents for reducing the copper toxicity to D. magna. The protective effects of EPS were estimated based on the accumulation of copper in the D. magna cells. Levan is a branched fructane EPS [2] and the one used in this study was produced by Bacillus licheniformis NS032. Pullulan, a linear glucan EPS [3], was produced by Aureobasidium pullulans CH-1. The D. magna were exposed to 50 µg/dm3  of Cu (II) or a combination with 50 mg/dm3  and 100 mg/dm3  of levan or pullulan for 48h in the acute test. Additionally, the prolonged test was performed, where the daphnia were exposed to a 10 µg/dm3  of Cu (II) with or without 50 mg/ dm3  of levan or pullulan for 5 days. After the exposure period, the samples were digested and the accumulation of copper in D. magna was analysed using the iCAP Qc ICP-MS (Thermo Scientific, United Kingdom). The results showed that animals exposed to Cu (II) only, accumulated Cu (II) in a greater amount after the prolonged test compared to the acute one, despite the lower concentration. The treatment with EPS during the acute test increased the copper accumulation for both EPS concentrations tested, whereas during the prolonged exposure test, the Cu (II) accumulation was inhibited. Considering that protective effects of levan and pullulan were observed only with lower copper concentrations and 5 days of exposure, additional experiments are necessary to determine the mechanism of EPS action in order to confirm their possible use as protective agents.

The D. magna were exposed to 50 µg/dm3  of Cu (II) or a combination with 50 mg/dm3  and 100 mg/dm3  of levan or pullulan for 48h in the acute test. Additionally, the prolonged test was performed, where the daphnia were exposed to a 10 µg/dm3  of Cu (II) with or without 50 mg/ dm3  of levan or pullulan for 5 days. After the exposure period, the samples were digested and the accumulation of copper in D. magna was analysed using the iCAP Qc ICP-MS (Thermo Scientific, United Kingdom). The results showed that animals exposed to Cu (II) only, accumulated Cu (II) in a greater amount after the prolonged test compared to the acute one, despite the lower concentration. The treatment with EPS during the acute test increased the copper accumulation for both EPS concentrations tested, whereas during the prolonged exposure test, the Cu (II) accumulation was inhibited. Considering that protective effects of levan and pullulan were observed only with lower copper concentrations and 5 days of exposure, additional experiments are necessary to determine the mechanism of EPS action in order to confirm their possible use as protective agents.",

AB  - Aquaphotomics is a relatively novel scientific discipline which can be used for elucidation of structural and  related functional properties of aqueous systems. The aim of this study was to analyse water solutions of carbohydrates of different size from monosaccharides (glucose and fructose) via, disaccharides (sucrose), gluco and fructo-oligosaccharides and various selected polisaccharides (based on glucose and fructose, respectively) using Aquaphotomics. Knowing that main functions of carbohydrates within our body are various: providing energy and regulation of blood glucose; sparing the use of proteins for energy; breakdown of fatty acids and preventing ketosis; biological recognition processes; flavor and sweeteners and dietary fibers who can promote digestive health, knowledge about their interaction with water molecules can have strong influence on our understanding of some basic but also complex metabolic processes.

AB  - One of the main global focuses of mankind today is the required switch to new energy sources. Generating energy from waste is one of the potential solutions that can be achieved using microbial fuel cells (MFCs). Microorganisms, thanks to their ability to degrade organic substrates in contaminated environments, could contribute to solving our pollution challenge. The aim of this study was to investigate the potential of sediment with its natural microbiota from the River Danube to optimize electricity generation using MFCs. 16S rRNA gene analysis identified the main bacterial genera in the river sediment, Clostridium, Bacillus and Tepidibacter, which were isolated and cultured in the laboratory. Addition of these cultured microorganisms to the MFC resulted in current density of 192 mA/m3, while the power density was about 8.80 mW/m3. Our study confirms proper selection and enrichment of the microbial community can optimize the amount of current obtainable from river sediment by MFCs.

AB  - Objects of the present study are improved fullerene C60 drug carrier properties trough encapsulation by microbial polysaccharides, levan (LEV), pullulan (PUL), and their hydrophobized cholesterol-derivatives (CHL and CHP), that show better interaction with cancer cells. The zeta potential, polydispersity index, and the diameter of particles were determined, and their cytotoxicity against three cancer cell lines were tested. Biochemical changes in HeLa cells are analyzed by synchrotron radiation (SR) FTIR spectro-microscopy combined with the principal component analysis (PCA). The most significant changes occur in HeLa cells treated with LEV-C60 and correspond to the changes in the protein region, i.e. Amide Iband, and the changes in the structure of lipid bodies and membrane fluidity are evident. The highest cytotoxicity was also induced by LEV-C60. In HeLa cells, cytotoxicity could not be strictly associated with biochemical changes in lipids, proteins and nucleic acids, but these findings are significant contribution to the study of the mechanism of interaction of C60-based nanoparticles with cellular biomolecules. In conclusion, LEV, PUL, CHL, and CHP enhanced fullerene C60potential to be used as target drug delivery system with the ability to induce specific intracellular changes in HeLa cancer cells.

AB  - An efficient encapsulation of the fullerene into two hydrophobized and one native polysaccharide provided water soluble supramolecular hybrids. After covalent modification of polysaccharides by cholesterol, noncovalent hybrids were prepared by a three-step procedure, including mixing of individual aqueous solutions of hydrophobized, as well as native sugar with solution of the fullerene in pyridine, dialysis and lyophilization. Although the degree of the fullerene incorporation into hydrophobized substrates, cholesterol-levan and cholesterol-pullulan, was lower in comparison to the native polysaccharide levan, hydrophobization provided nanoparticles with improved properties. The particle size distribution, studied by dynamic light scattering and scanning electron microscopy revealed formation of moderately polydisperse aggregates, with the diameter contraction in comparison to the corresponding free polysaccharide, especially in the case of hydrophobized substrates. The morphological examination, done by scanning electron microscopy indicated the self-organization of the fullerene-native polysaccharide to round individual structures, while fullerene-hydrophobized polysaccharide hybrids tend to form networks. The antioxidant activity of the synthesized polysaccharide-C60 noncovalent hybrids versus starting polysaccharides was investigated by the DPPH radical scavenging and the β-carotene-linoleic acid bleaching methods. In all three complexes, the radical scavenging ability of the fullerene remained preserved, and a positive effect of levan hydrophobization was observed.

AB  - The production of levan by Bacillus licheniformis NS032 in a medium based on sugar beet molasses was studied. High polysaccharide yields were produced by using diluted molasses (100–140 g/L of total sugars) with the addition of commercial sucrose up to 200 g/L of total sugars, as well as K2HPO4. A levan yield of 53.2 g/L was obtained on a medium optimized by response surface methodology, containing 62.6% of sugar originating from molasses, and 4.66 g/L of phosphate, with initial pH value of 7.2. In comparison to the media with 200 and 400 g/L sucrose, in the molasses optimized medium, the observed bacterial growth was faster, while the maximum production of polysaccharide was achieved over a shorter time interval (48 h). The polysaccharide produced in molasses medium had a weight average molecular weight of 5.82 × 106 Da, degree of branching 12.68%, viscosity of 0.24 dL/g, and based on methylation analysis and NMR data, it did not significantly differ from levan obtained in the medium with 200 g/L sucrose. © 2018 Elsevier B.V.

AB  - Polycyclic aromatic hydrocarbons (PAHs) from petroleum and fossil fuels are one of the most dominant pollutants in the environment. Since aromatic fraction from petroleum diesel fuel is mainly composed of PAHs, it is important to discover new microorganisms that can biodegrade these compounds. This article describes the biodegradation of the aromatic fraction separated from petroleum diesel fuel using the strain Oerskovia sp. CHP-ZH25 isolated from petroleum oil-contaminated soil. The biodegradation was monitored by gravimetry and GC × GC-TOF MS. An innovative method was applied to visualize degraded compounds in the data provided by a GC × GC-TOF MS. It was shown that Oerskovia sp. CHP-ZH25 degraded 77.4% based on gravimetric analysis within 30 days. Average rate of degradation was 14.4 mg/L/day, 10.5 mg/l/day and 4.0 mg/l/day from 0 to 10 day, 10–20 and 20–30 day, respectively. The order of PAH degradation based on decrease in peak volume after 30 days of incubation was as follows: dibenzothiophene derivatives  gt  benzo[b]thiophene derivatives  gt  naphthalene derivatives  gt  acenaphthene derivatives  gt  acenaphthylene/biphenyl derivatives  gt  fluorene derivatives  gt  phenanthrene/anthracene derivatives. Here we demonstrated that Oerskovia sp. CHP-ZH25 could potentially be a suitable candidate for use in bioremediation of environments polluted with different PAHs. © 2018 Elsevier B.V.

AB  - The analysis of the electric, magnetic and electromagnetic fields influence on microorganisms is a very popular research topic, since these fields could potentially act as stressors and affect the microbial metabolism and survival. The aim of this work was to investigate the influence of the low frequency magnetic field (MF) with scan regime from 10 Hz to 50 Hz on S. cerevisiae respiration. The experiment was performed in five replicates and monitored using the Micro-Oxymax® respirometer. All five experiments showed lower cumulative O2 consumption in MF exposed samples, compared to the control sample and inconsistent cumulative CO2 production. However, these differences in O2 consumption and CO2 production were statistically significant. Even though additional experiments are necessary, these results strongly suggest that this is a good basis for further investigation in this field.
AB  - Ispitivanje uticaja električnog, magnetnog i elektromagnetnog polja na mikroorganizme jeveoma aktuelni predmet istrazivanja, jer ova fizička polja potencijalno deluju kao faktoristresa i tako utiču na mikrobni metabolizam, ponašanje i preživljavanje.

abstract = "The analysis of the electric, magnetic and electromagnetic fields influence on microorganisms is a very popular research topic, since these fields could potentially act as stressors and affect the microbial metabolism and survival. The aim of this work was to investigate the influence of the low frequency magnetic field (MF) with scan regime from 10 Hz to 50 Hz on S. cerevisiae respiration. The experiment was performed in five replicates and monitored using the Micro-Oxymax® respirometer. All five experiments showed lower cumulative O2 consumption in MF exposed samples, compared to the control sample and inconsistent cumulative CO2 production. However, these differences in O2 consumption and CO2 production were statistically significant. Even though additional experiments are necessary, these results strongly suggest that this is a good basis for further investigation in this field., Ispitivanje uticaja električnog, magnetnog i elektromagnetnog polja na mikroorganizme jeveoma aktuelni predmet istrazivanja, jer ova fizička polja potencijalno deluju kao faktoristresa i tako utiču na mikrobni metabolizam, ponašanje i preživljavanje.
