BIODEGRADATION OF SELECTED PETROLEUM PRODUCTS UNDER VARIABLE ENVIRONMENTAL TEMPERATURE AND PH CONDITIONS

Keywords: biodegradation, microorganisms, oil products
Abstract: In the paper is presented the biodegradability of selected petroleum products with the participation of selected bacterial strains of the genera Pseudomonas sp. and Bacillus sp. The experiment was carried out on liquid culture media. The examined products were found to show different biodegradability, with maximum value ranging from 65% for gear oil, through 90% for diesel fuel to 95% for motor oil after 28 days of incubation. The study results point to highly significant effect of environmental factors, i.e. temperature and pH, on the speed and efficiency of the course of biodegradation process, with optimal conditions for the examined products being within the range of 6.5–8 for pH and 5–25°C for temperature.
