AB  - Contamination of soil, groundwater, sediment, surface water and air, hazardous waste such as oil and by-productsarising during processing of oil, pose a major problem the world faces today.Catalysts used in the desulphurisation process oil can be a source of pollution with heavy metals and are thereforetested their chemical properties, as well as their impact on the growth of microbial consortium in the process of bioremediation, which is isolated from the waste of fuel oil from the PUC “Belgrade power plants” and waste motor oil. Weexamined five different catalysts that are derived from the Oil Refinery Pancevo, a metal that is focused attention asMo (molybdenum) and Co (cobalt).The efficiency of bacterial cells in concentrating metal has enabled their high ratio of surface area to volume and highcharge density on the cell surface. Entire bacterial cell is negatively charged due to the presence of different anions.Therefore, the bacterial cell walls have a strong affinity for metal cations. Intact bacterial cells, regardless of whetherthey are alive or dead, as their products are also very effective in accumulating metals.

AB  - Nafta i naftni derivati kao što su dizel, benzin i mazut mogu dospeti u vodu, zemljište i sediment i predstavljaju rizik za životnu sredinu i čoveka [1-3]. Tehnologijom bioremedijacije, koristeći prirodnu sposobnost mikroorganizama da rastu na ugljovodonicima kao supstratima, nafta i naftni derivati se mogu ukloniti iz zagadjene životne sredine. Biološki tretmani su isplatljiviji i „prijateljski za okolinu”, a kao krajnji rezultat zagadjujuća supstanca se potpuno razgradjuje ili se dobijaju jedinjenja sa smanjenom toksičnošću. Da bi se vršili eksperimenti biodegradacije i bioremedijacije, neophodno je utvrditi poreklo i prirodu zagadjujuće supstance i okarakterisati autohtone mikroorganizme sa mesta zagadjenja. Cilj ovog rada bio je da se identifikuju zagadjujuće supstance na teritoriji Toplane Novi Beograd. Uzorci su uzeti sa tri različita mesta na lokaciji. U uzorcima je praćen sadržaj ukupnih ugljovodonika nafte (TPH). TPH je ekstrahovan [ISO 16703] i gravimetrijski odredjen [DIN EN 14354]. Odredjivanje TPH gasnom hromatografijom vršeno je na gasnom hromatografu Agilent 7890A sa FID detektorom. Pored gasne hromatografije odredjivan jebroj mikroorganizama na osnovnim i selektivnim podlogama. Na osnovu dobijenih rezultata utvrdjeno je da su glavne zagadjujuće supstance na tačkama 1 i 2 u okviru lokacije Toplane Novi Beograd benzin i dizel, dok u tački 3 preovladava dizel sa manjom količinom mazuta. Ukupan sadržaj naftnih ugljovodonika u uzorku 1 je 3640 mg/kg, uzorku 2 2760 mg/kg, dok je u uzorku 3 taj broj oko deset puta veći, 28865 mg/kg. Tačka označena sa brojem tri je iznad remedijacione vrednosti na osnovu pravilnika i zakonskih propisa. U sva tri uzorka nadjen je veliki broj mikroorganizama koji razgradjuju ugljovodonike ̴ 105 CFU/g, od kojih su dominantni rodovi Pseudomonas, Achromobacter, Rhodococcus, Microbacterium što je u skladu sa literaturom [1]. U okviru ovog rada uspešno su identifikovane zagadjujuće supstance i odredjeni rodovi dominantnih autohtonih mikroorganizama na lokaciji Toplane Novi Beograd.

AB  - The aim of this paper was to investigate whether changes in the quantity and structure of humic acids (HA) occur during bioremediation of waste mazute (heavy residual fuel oil). The effects of humification on the structure of HA were evaluated by Fourier Transform Infrared Spectroscopy (FT-IR), potentiometric titrations, the ratio of absorbances at 465 and 665 nm (E4/E6 ratio) and the ratio. Also, the quality of humification was monitored by determining parameters which are important for measuring the evolution of humic substances (HS), such as CHA/CFA (the humic acidifulvic acidratio), the rate of extraction (TE) and the index of polymerization (IP). An increase of the content of HA from 0.23% to 0.70% was observed during the bioremediation process. The FT-IR spectra and 04 ratio of HA extracted at the beginning and the end of the process indicate structural changes during the bioremediation process. The groups containing aromatic and carboxylic carbon increased, resulting in HA structures of higher aromaticity. An increase of the B4/E6 ratio during bioremediation treatment implied the enrichment of HA with functional oxygen groups. Potentiometric titrations of HA solution showed increases in the buffering and the redox capacities of HA during the bioremediation process. The results of parameters of humification showed an increase of the compositional carbon in HA at the end, compared to at the start, of bioremediation, while the carbon that belonged to fulvic acids (FA) reduced by 44%. Transformation into HA is the likely cause of this observed reduction. The TE and the IP demonstrated that humification occured during the bioremediation process. According to the available data, this is the first report on synthesis of HS during bioremediation of petroleum hydrocarbons. (C) 2017 Published by Elsevier Ltd.

Naime, neki istraživači smatraju da tokom biorazgradnje policikličnih aromatičnih ugljovodonika (PAH) nastaju supstance slične huminskim, što je veoma značajno, s’ obzirom da huminske supstance predstavljaju jedan od ključnih elemenata kvaliteta zemljišta.  U cilju ispitivanja navedene hipoteze, dizajniranirano je pilot postrojenje za  bioremedijaciju, i praćenje promena u ugljovodoničnom sastavu, kao i promena u sastavu huminskih supstanci.
