Study of the Oil-Degrading Activity of Caspian Shore Microflora

Soil samples from the shore of Baku Bay (Caspian Sea) were studied. The content of oil products in the samples amounted to 2.7-8.0 wt %. The total counts of microorganisms were 1.8 × 10^sup 6^ cells per g soil, which is by two orders of magnitude lower compared to soils free from oil pollution. In a...

Summary:Soil samples from the shore of Baku Bay (Caspian Sea) were studied. The content of oil products in the samples amounted to 2.7-8.0 wt %. The total counts of microorganisms were 1.8 × 10^sup 6^ cells per g soil, which is by two orders of magnitude lower compared to soils free from oil pollution. In addition, the diversity of microflora is considerably narrower. The samples were used to isolate pure cultures of microbial degraders capable of assimilating 24 to 32% of the oil introduced into liquid nutrient medium in six days. It was demonstrated that the fraction composition of residual oil changed and both light and heavy oil fractions were degraded.[PUBLICATION ABSTRACT]
