Abstract
In review the present situation of petroleum pollution, its consequences and basic oil composition are
described. The up to date survey of hydrocarbon degradation microbiology and major strains are presented
with respect to following practical introduction of obtained data. A general characteristic of oil
hydrocarbons biodegradation is done. Biodegradation metabolism of petroleum products different categories
and its biochemistry are described. Principal biochemical pathways are indicated. Biotechnological
properties of hydrocarbon degrading microorganisms including that of industrial significance are investigated.
Much attention is given to biological and environmental factors that influence completeness and
rate of hydrocarbons biodegradation. It was established that microorganisms consortium biodegradation
is faster and more complete that single species ones. The effects of hydrocarbons presence in medium on
biochemical and cytological levels of microbial metabolism are also analyzed. The major methods of microbial
resistance to petroleum products toxic influence are described. It is shown that one of the most important
among them is metabolic processes shifting towards surfactants.
