Six strains of oil-degrading bacteria isolated from the endosphere and rhizosphere of plants growing on oil polluted soils of the Irkutsk region were studied to determine the pathways for biodestruction of polyaromatic oil hydrocarbons. All strains were able to efficiently degrade polyaromatic hydrocarbons with the formation of pyrocatechin as a final product; strains 90, 108, and 112 additionally formed protocathechuic acid. The culture broth of the studied strains contained ferulic, n-coumaric, n-oxybenzoic, vanillic, and lilac acids, which probably represent metabolites of cinnamic alcohol, cinnamic aldehyde, and benzoic acid presenting in oil and metabolized by bacteria.
