Oil-oxidizing activity of bacteria isolated from south Sakhalin coastal waters

Аннотация

Ability of bacteria isolated from the southern coastal waters of the Sakhalin Island to degrade various hydrocarbons was studied. The population of marine microorganisms grown on oil was heterogeneous in terms of hydrocarbon degradation. The rate of bacterial degradation of oil hydrocarbons was shown to correlate with their growth rate on the model medium. The degradation rates were higher for aromatic hydrocarbons than for alkanes. Based on our data, the studied bacteria were conditionally assigned to three groups: active, intermediately active, and passive degraders. Ability to oxidize oil was previously not reported for members of the genus Cobetia.
