Research Advances on Bioremediation of Crude Oil Pollution

This article overviews the study of the effect(factors) of crude oil bioremediation over last several years.The main effect(factors include:) 1.microbial species,which seem to have different degradation rate under varied circumstances and n-alkanes;2.physical and chemical properties of crude oil itself,which have an important effect on biodegradation,such as conglutination,boiling point,refractive index,ingredient and concentration of the oil;and 3.culture condition of microorganism,under which the degrading activity of microorganism will be affected by surfactant,light condition,sorbent,nutrition,co-metabolite,oxygen,temperature and salinity during the inoculation of selected or indigenous microorganisms.
