Assessment of the influence of ambient temperature and soil salinity on the degree of destruction of oil by free and immobilized microorganisms

Due to the annual increasing volumes of oil and petroleum products extraction refining, probability ecosystem pollution with heavy hydrocarbons is increasing. At present, it biological methods soil purification that are most promising from both an ecological economic point view. The main mining regions characterized by a hot climate high salinity soil. It known effectiveness use destructive microorganisms largely depends on external environmental factors. Abiotic factors ambient temperature initial directly affect metabolic processes bacteria. purpose this work was study ability free immobilized carriers degrade under different conditions at concentrations mineral salts in found increase salinity, degree destruction decreases. However, temperature, level remained same as 5% NaCl. influenced factor. highest result was shown strains rice husk. Whereas buckwheat husks cells show low purification. Immobilization solid organic carriers, protect influences fluctuations temperature. Key words: bioremediation, immobilization, husk, microorganisms.
