Zagađenje vode, zemljišta i sedimenta naftom i njenim derivatima, može se javiti tokom eksploatacije, transporta i skladištenja i predstavlja rizik za životnu sredinu i ljudsko zdravlje. Bioremedijacija je zelena tehnologija kojom se uklanja zagađenje iz kontaminirane životne sredine upotrebom mikroorganizama. U ovom radu su praćene promene u sadržaju mineralnih ulja i aktivnost mikroorganizama koji razgrađuju ugljovodonike tokom procesa bioremedijacije koji je trajao 210 dana. Rezultati ukazuju da mikroorganizmi koji razgrađuju ugljovodonike sa visokom efikasnošću degraduju mineralna ulja. Na osnovu količine mineralnog ulja (smanjena za 63,82 %), stepena degradacije i udela mikroorganizama naftnih degradera u ukupnom broju mikroorganizama, može se zaključiti da su faza adaptacije konzorcijuma i faza intenzivne razgradnje bile u periodu od 0. do 90. dana, praćene dalje sporijom fazom razgradnje u periodu od 90. do 210. dana. Pollution of water, soil and sediment with petroleum and its products may occur during the exploitation, transportation and storage and it poses a risk to the environment and human health. Bioremediation is a green technology that can remove pollution from contaminated environment using microorganisms. In this paper changes in the content of mineral oil and the activity of hydrocarbon degraders during remediation process that lasted 210 days were monitored. The results indicate that hydrocarbon degrading microorganisms with high efficiency have biodegraded mineral oil. Based on the amount of mineral oil (decreased for 63.82 %), degradation rates and level of hydrocarbon degraders in the total number of microorganisms, we note that the stages of adaptation of the consortium and intensive degradation phases were in the range of 0-90 days, followed by a slower decomposition phase in the period of 90-210 days.

Nattō is a traditional Japanese dish made from fermented soybeans and is usually combined with soy sauce. It is very rich in vitamins, amino acids, proteins, sugars, fats, minerals and dietary fibres, and polypeptides consisting of 275 amino acid residues with anticoagulant, fibrinolytic, blood pressure lowering effects and antioxidant activity. Bacillus subtilis natto belongs to the Bacillus subtilis species and it is the basis for the production of traditional Japanese food. Poster: [https://cherry.chem.bg.ac.rs/handle/123456789/5389]

Chemical and biochemical activities of microorganisms are obvious in industrial biotechnology. They are becoming even more important in environmental biotechnology and circular economy. The application of microorganisms in remediation, environmental protection and management have proven that they are "biological agents" of choice. In bioremediation processes they may be used for the treatment of waste water as well as for polluted surface and underground waters, polluted soil and process gases, i.e. indirectly, even for polluted air. In situ and ex situ bioremediation procedures for the treatment of soil and underground water contaminated by oil derivatives with the application of zymogenous active microbial consortia on the industrial level have shown in our multi-year practice to be very effective and applicable in all aspects. During biodegradation of oil pollutants, the soilification of the substrate has occurred through the process of humification. Laboratory experiments dealing with the recovery of a number of elements from electronic waste (printed circuit boards) with the application of the bacterial species Acidithiobacillus ferrooxidans that generates/regenerates iron(III)-ion as an active reagent for the solution of metals have proven that biohydrometallurgical procedures have potential application in the recycling and reuse of technically important metals such as are rare earth elements-REE (critical materials). It may be concluded that microorganisms are undoubtfully the most useful "green" agents in the area of environmental protection and in the future, in circular economy of some of critical elements. Microorganisms are inseparable from the green chemistry and engineering and they are an important link in the sustainable development. Poster: [https://cer.ihtm.bg.ac.rs/handle/123456789/5488]

This study was focused on investigating researching humification process during the ex situ experiment of bioremediation of soil contaminated with petroleum and its products from Rafinery Pančevo.

The aim of this paper is to study the use of different microorganisms as “biological agents” through processe which are of crucial importance for soil formation. The processe includes the study of an active consortium of zymogenous microorganisms for ex situ bioremediation of a complex petroleum contaminant in soil substrate, along with simultaneous monitoring of the humification process.

The aim of our study was to analyze the potential of allochthonous and autochthonous microorganisms in the process of biodegradation of PCBs from sediments of the river to protect the environment and future potential treatment of these sites.

The aim of our study was to analyze the potential of allochthonous and autochthonous microorganisms for the process of biodegradation of PCBs in sediment samples collected from rivers in the territory of Belgrade, Serbia to protect the environment and estimate future treatment of these sites.
