AB  - 24-epibrassinolide (24-EBL) is plant steroid hormone that can regulate several physiological effects in plants, including promotion of cell growth and induction of heat stress tolerance. The purpose of this work is to investigate the influence of various concentrations of 24-EBL on the dehydration mechanism of seedlings of two maize hybrids (ZP434 and ZP704). Control and treated samples were subjected to isothermal conditions for dehydration processes. The effects of carbohydrates and mineral contents on the possible changes in the dehydration mechanism (from kinetics standpoint) were investigated. Comparing control samples to samples treated with 24-EBL, it was found that different dehydration mechanisms exist The differences arise from the influence of 24-EBL, that causes a significant increase of phosphorus values for ZP704, whilst the reverse was identified for ZP434. It was assumed that the plumule sensitivity to dehydration stress originates from the interaction of water with primary amino groups as cations in polyamines, for lower concentrations of 24-EBL. It was found that the temperature variation (105-130 degrees C) leads to situations where trehalose does not arrive fast enough to "replace the water", because its handicap to binds (by hydrogen bonds) to biomolecules instead of water. It was found that 24-EBL cause changes of carbohydrates properties, which are important for the defense mechanism from environmental stresses. (C) 2018 SAAB. Published by Elsevier B.V.

AB  - In this study, influence of wide range of 24-epibrassinolide (24-EBL) on early growth potential of two maize hybrids (ZP 434 and ZP 704) was examined. Paper concerns germination, seedling biomass, important chlorophylls content, and redistribution of elements (heavy metals and microelements), in a seedlings of the maize hybrids, as influenced by different 24-EBL concentrations. It was found that hybrids react differently to exogenously applied hormone. The biggest differences between two examined maize hybrids considering the germination level were reached with the lowest values at 86% for ZP 704 and 72% for ZP 434, gained at the highest applied concentration of 24-EBL. Seedlings of hybrid ZP 434 reacted positively moderately in the case of shoot length and biomass under the influence of 24-EBL, but seedlings of hybrid ZP 704 had lower values of these parameters under the influence of the phytohormone. Chlorophyll a/b ratios showed that photosynthetic apparatus of seedlings of the hybrids is not active in this stage of development. It was established that 24-EBL affects seedling growth and re-allocation of naturally present mineral elements in early growth stages and that could be one of the reason for poorer growth of ZP 704 treated with various concentrations of 24-EBL, comparing to control. When applied in lower concentrations, 24-EBL is blocking toxic elements such as chromium and nickel to relocate to vital parts of plant, what was case in hybrid ZP704. In case of ZP 434, lower concentrations of 24-EBL are affecting re-allocation of Cu and Cr and these findings suggest that maize hybrid seedlings treated with lower concentrations of 24-EBL could survive and be successful in polluted areas.

AB  - Proposed distributed reactivity model of dehydration for seedling parts of two various maize hybrids (ZP434, ZP704) was established. Dehydration stresses were induced thermally, which is also accompanied by response of hybrids to heat stress. It was found that an increased value of activation energy counterparts within radicle dehydration of ZP434, with a high concentration of 24-epibrassinolide (24-EBL) at elevated operating temperatures, probably causes activation of diffusion mechanisms in cutin network and may increases likelihood of formation of free volumes, large enough to accommodate diffusing molecule. Many small random effects were detected and can be correlated with micro-disturbing in a space filled with water caused by thermal gradients, increasing capillary phenomena, and which can induce thermo-capillary migration. The influence of seedling content of various sugars and minerals on dehydration was also examined. Estimated distributed reactivity models indicate a dependence of reactivity on structural arrangements, due to present interactions between water molecules and chemical species within the plant.

AB  - Coal and lignite play a major energy supply role in many European countries, including Bosnia and Herzegovina. Yet mining activities are a heavy source of ecosystem contamination, posing significant environmental threats. The primary goal of this study was to isolate and identify autochthonous lignite mine spoil bacteria and evaluate their potential in bioremediation of these polluted soils. Two Bacillus species, Bacillus simplex and a Bacillus cereus group member, were identified using conventional, molecular, and bioinformatics approaches. This represents, to our knowledge, the first microbial characterization of mine overburden in Bosnia and Herzegovina. A co-inoculum of autochthonous bacterial populations was used to treat unvegetated as well as oat- and lettuce-vegetated lignite overburden samples. Our results illustrate the potential of recovered native species to enrich soil fertility and productivity through plant growth promotion.

AB  - Due to the frequent use of fossil fuels, which has negative effects on the environment, there is a need to find a new, environmentally acceptable replacements for fossil fuels. One of the possible replacement is the inclusion of green technologies, in order to obtain the type of fuel that would be acceptable from an environmental and economic point of view. Biodiesel represents renewable and less toxic substituent for fossil fuels, which consists of esters of higher fatty acids and depending on the environmental conditions, can be manufactured from various types of oils, both plant and animal origin. Since corn is one of the most cultivated plants in Serbia, the research included the transesterification reaction of corn oil on a heterogeneous catalyst. The paper examined the activity of heterogeneous base catalyst (CaO/γ-Al2O3) and the influence of various parameters on the conversion of corn oil. From the optimization of process parameters, it was found that the optimal conditions for transesterification of corn oil to 25% CaO/γ-Al2O3: molar ratio of methanol to oil 1:12; stirring speed 900rpm; reflux temperature of the methanol; reaction time of 6 hours; the amount of catalyst in the reaction of 5wt.%.

AB  - High-performance thin-layer chromatography (HPTLC) combined with image analysis and pattern recognition methods were used for fingerprinting of phenolic compounds present in seedlings of two maize genotypes ZP 434 (new generation hybrid, drought tolerant) and ZP 704 (older generation hybrid, drought sensitive) treated with different concentrations of 24-epibrassinolide. This is the first report of TLC chromatographic profile of phenolics' mixtures in maize seed extracts influenced by brassinosteroid phytohormones. Nine samples of shoot of seedlings for the whole concentration range of phytohormones (5.2 x 10(-7) -5.2 x 10(-15) M), one sample of root of seedlings treated with 5.2 x 10(-15) M 24-epibrassinolide, and the control samples of nontreated seedlings, for both genotypes, were analyzed. Phenolic profiles of root extracts indicate the absence of more polar compounds such as phenolic acids and glycosides present in shoot of seedlings. Also, hormones applied in higher concentrations have an inhibiting effect on the content of phenolics in ZP 434. Application of chemometric methods enables characterization of particular genotype of maize according to its phenolic profile.

abstract = "High-performance thin-layer chromatography (HPTLC) combined with image analysis and pattern recognition methods were used for fingerprinting of phenolic compounds present in seedlings of two maize genotypes ZP 434 (new generation hybrid, drought tolerant) and ZP 704 (older generation hybrid, drought sensitive) treated with different concentrations of 24-epibrassinolide. This is the first report of TLC chromatographic profile of phenolics' mixtures in maize seed extracts influenced by brassinosteroid phytohormones. Nine samples of shoot of seedlings for the whole concentration range of phytohormones (5.2 x 10(-7) -5.2 x 10(-15) M), one sample of root of seedlings treated with 5.2 x 10(-15) M 24-epibrassinolide, and the control samples of nontreated seedlings, for both genotypes, were analyzed. Phenolic profiles of root extracts indicate the absence of more polar compounds such as phenolic acids and glycosides present in shoot of seedlings. Also, hormones applied in higher concentrations have an inhibiting effect on the content of phenolics in ZP 434. Application of chemometric methods enables characterization of particular genotype of maize according to its phenolic profile.",

AB  - Methyl-tert-butyl ether (MTBE) has been used to replace the toxic compounds from gasoline and to reduce emission of air pollutants. Due to its intensive use, MTBE has become one of the most important environment pollutants. The aim of this study was the isolation and identification of the bacteria from wastewater sample of 'HIP Petrohemija', Pančevo (Serbia), capable of MTBE biodegradation. The results of the investigation showed that only the bacterial isolate 27/1 was capable of growth on MTBE. The result of sequence analyzes of 16S rDNA showed that this bacterial isolate belongs to the Kocuria sp. After the incubation period of 86 days, the degradation rates of initial MTBE concentration of 25 and 125 μg/ml were 55 and 36%, respectively. These results indicated that bacteria Kocuria sp. is successfully adapted on MTBE and can be potentially used in bioremediation of soils and waters contaminated with MTBE.
AB  - Metil tercijarni butil etar (MTBE) uveden je u proizvodnju s ciljem zamene toksičnih komponenti iz benzina, povećanja oktanskog broja goriva i redukcije aerozagađenja. Usled intenzivne primene, perzistentnosti i mobilnosti, MTBE je posle svega nekoliko godina postao značajan polutant u životnoj sredini. Cilj ovog rada je izolacija i identifikacija bakterija iz uzorka otpadne vode poreklom iz 'HIP Petrohemije', Pančevo, sposobnih da vrše degradaciju MTBE-a. Od 11 bakterijskih izolata, svrstanih u tri grupe po morfološkim osobinama, samo je jedan izolat, označen kao 27/1, pokazao sposobnost rasta na MTBE-u kao jedinstvenom izvoru ugljenika i energije i odabran je za dalja istraživanja. Ovaj izolat ima sitne crvenkaste kolonije na podlozi 0,1×TSA. Ćelije su okruglastog oblika, ne stvaraju spore a po Gramu se boje pozitivno. Primenom API i APIWEB sistema, ovaj izolat pokazuje najveći stepen sličnosti sa bakterijskom vrstom Kocuria rosea. Sekvenca izolata 27/1 dobijena sekvencionom 16S rDNA analizom se sastoji od 1407 nukleotida, na osnovu čega je ovaj izolat identifikovan kao Kocuria sp. Nakon inkubacije od 86 dana, stepen degradacije početnih koncentracija MTBE-a od 25 i 125 μg/ml iznosio je 55, odnosno 36%. Pri početnoj koncentraciji od 25 μg/ml optička gustina i brojnost bakterija se smanjuju u prvih 15 dana inkubacije, dok je pri početnoj koncentraciji od 125 μg/ml zabeleženo smanjenje optičke gustine i broja bakterija u prvih 30 dana. Nakon ovog perioda, stepen bakterijskog rasta se povećava. U početnim fazama Inkubacije, stepen degradacije MTBE-a nije visok, dok je krajem inkubacionog perioda konstatovan najveći stepen degradacije. Ovi rezultati ukazuju na uspešnu adaptaciju bakterije Kocuria sp. na prisustvo MTBE-a, što opravdava njenu primenu u bioremedijaciji zemljišta i voda kontaminiranih MTBE-om.

AB  - Methyl tertiary butyl ether (MTBE) belongs to the group of gasoline oxygenates and persistent environment contaminants, and shows potential for biodegradation in aerobic and anaerobic conditions, through application of pure microbial cultures. Presented research shows that indigenous bacterial isolates 6sy and 24p, selected from oil hydrocarbons-contaminated environments, were capable of utilizing MTBE as sole carbon and energy source. Based on 16S rDNA sequence analysis, bacterial isolates 6sy and 24p were identified as Staphylococcus saprophyticus subsp. saprophyticus and Pseudomonas sp., respectively. The MTBE biodegradation rate was affected by longevity of incubation period and initial MTBE concentration. After 3 weeks of incubation at 25 degrees C in a dark, the removal rates of initial 25 and 125 ppm MTBE concentrations by Staphylococcus saprophyticus 6sy were found to be 97, and 63%, respectively, while efficiency of Pseudomonas sp. in degradation of indicated concentrations was 96, and 40%, respectively. Both bacterial isolates were able to grow in MTBE-containing growth medium. Highest growth rate of bacterial isolates was observed at the end of incubation period. The presented results indicated the potential of these bacterial isolates in bioremediation of MTBE-contaminated environments.
