This paper describes the problem of oil pollutant re moval and the use of Acinetobacter genus microor ganisms in oil biodegradation. As part of the experi ments, Acinetobacter genus microorganism strain with the best ability to degrade crude oil and fuel oil in saline waters was selected from the microorganism collection of JSC "Biocentras". The impact of environmental con ditions (salinity, temperature, pH, substrate concent ration) on this strain's viability and the efficacy of its oil degradation processes were evaluated. The most ef ficient degradation of oil products by Acinetobacter ge nus bacteria was at temperature of 30 °C, in a pH range of 7-8, in model ocean water of 35 ‰ salinity.
