Pathways of aerobic petroleum oil hydrocarbons biodegradation
Languages of publication
The paper reviews the aspects of physiology and biochemistry of microbial biodegradation of the main components of petroleum oil: alkanes (larger than methane), alkenes, alkines, cyclic, polycyclic, aromatic and polyaromatic hydrocarbons. It focuses on aerobic degradation pathways. The review provides key information prepared on the basis of more than 30 years of research on microbial degradation of hydrocarbons. The areas discussed include new pathways of biodegradation of branched-chain alkanes, cyclic and polyaromatic hydrocarbons which have been discovered during the past few years. Special attention was paid to oxygenases ? enzymes initiating aerobic metabolism of hydrocarbons and phenomenon of co-oxidation which enables assimilation of most recalcitrant components of crude oil.
