Oil degradation by basidiomycetes in soil and peat at low temperatures

A total of 17 basidiomycete strains causing white rot and growing on oil-contaminated substrates have been screened. Three strains with high ( Steccherinum murashkinskyi ), average ( Trametes maxima ), and low ( Pleurotus ostreatus ) capacities for the colonization of oil-contaminated substrates hav...

Description
Summary:A total of 17 basidiomycete strains causing white rot and growing on oil-contaminated substrates have been screened. Three strains with high ( Steccherinum murashkinskyi ), average ( Trametes maxima ), and low ( Pleurotus ostreatus ) capacities for the colonization of oil-contaminated substrates have been selected. The potential for degrading crude oil hydrocarbons has been assessed with the use of fungi grown on nonsterile soil and peat at low temperatures. Candida sp. and Rhodococcus sp. commercial strains have been used as reference organisms with oil-degrading ability. All microorganisms introduced in oil-contaminated soil have proved to be ineffective, whereas the inoculation of peat with basidiomycetes and oil-degrading microorganisms accelerated the destruction of oil hydrocarbons. The greatest degradation potential of oil-aliphatic hydrocarbons has been found in S. murashlinskyi. T. maxima turned out to be the most successful in degrading aromatic hydrocarbons. It has been suggested that aboriginal microflora contributes importantly to the effectiveness of oil-destructing microorganisms. T. maxima and S. murashkinskyi strains are promising for further study as oil-oxidizing agents during bioremediation of oil-contaminated peat soil under conditions of low temperatures.
