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 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 کاملScreening, Optimization and Production of Biosurfactants by Candida Species Isolated from Oil Polluted Soils
Biosurfactants are amphipathic molecules with both hydrophilic and hydrophobic moieties and are surface active agent that are produced extracellularly or as a part of cell membrane by bacteria, yeast and fungi. In the present study, six different microorganisms were isolated from oil contaminated soils. Screening of biosurfactant producing potential strain was done using oil spreading method, o...
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 کاملAnalysis of hexavalent chromium uptake by plants in polluted soils
Concentration levels of hexavalent chromium in contaminated soil and in Zea mays plant parts were determined and Cr(VI) bioaccumulation and bioconcentration capacity of this plant were discussed. Zea mays seeds were sown in 40 mg Cr(VI)/kg dw polluted soil. After harvesting it was observed that hexavalent chromium concentrations in plant organs decreased in the following order: roots > stems > ...
