Role of microorganisms in bioremediation of oil polluted soils
The comparative analysis of microbial communities of pure and oil – polluted soils of Ukraine conducted by us has shown the considerable predominance in the latter the representatives of Rhodococcus and Gordonia genera. Among them the most part of strains belonged to the species of Rhodococcus erythropolis and Gordonia rubripertincta. Rhodococcus fascians, Rhodococcus ruber and Dietzia maris sp...

متن کاملBioremediation of Phenanthrene Polluted Soils
The best metabolic conditions for the biodegradation of hydrocarbons by a selected microbial consortium from a natural soil were investigated in order to improve the efficiency of bioremediation processes for cleaning of polluted waters and soils. Phenanthrene is one of the most recalcitrant pollutants to microbial decomposition and most difficult to remove. A microbial consortium was selected ...
متن کاملDegradation of anthracene by bacteria isolated from oil polluted tropical soils.
Four bacteria, identified as Pseudomonas aeruginosa, Alcaligenes eutrophus, Bacillus subtilis and Micrococcus luteus were isolated from crude oil polluted soils using anthracene as the sole carbon and energy source. All the organisms utilized n-hexadecane, n-tetradecane, diesel oil, engine oil and naphthalene as sole carbon sources. None could utilize hexane, cycloheptane, xylene, benzene, tolu...
متن کاملMicrobial populations of crude oil spill polluted soils at the Jordan-Iraq desert (the Badia region)
Microbial populations' inhabitants in crude petroleum contaminated soils were analyzed in relation with the soil characteristics. A noticeable greater decline of bacterial counts and diversity but a prevalence of the genus Pseudomonas over the other identified genera in the fresh contaminated soils as compared to the old ones was observed.
