Abstract:
Oil degradation by cultures of Rhodococcus erythropolis and Dietzia maris was found to depend on the NaCl concentration in the medium. Optimal utilization of turbine oil by R. erythropolis and D. maris was observed at 0.5 and 2 to 5% NaCl concentration, respectively. Mineral oil and a mixture of paraffins (C14-C18) were utilized within a broader range of the medium salinity. As shown by fluorescent microscopy, D. maris colonies formed on the oil drop surface, whereas R. erythropolis cells penetrated the drops. The strains studied may populate various ecological niches in oil-containing ecosystems. They are promising for the development of microbial preparations for cleaning the environment from oil pollution.
