Biodegradation is cost-effective, environmentally friendly treatment for oily contaminated sites by the use of microorganisms. In this study, laboratory experiments were conducted to study the influence of bacterial isolated in degradation of hydrocarbons contained in oily sludge from Oil Refinery plant in Shengli oil field China. The influence of pH, microbe amount, glucose concentration, salt concentration, rotate speed and temperature were investigated to evaluate the fermentation of Hydrocarbon degrading strain HJ-1 in shake flask. The oil degradation rate of strain HJ-1 was rise from 78.6% to 82.0% for crude oil and from 69.4% to 77.4% for oily sludge from refinery, as the fermentation bacteria solution was added into the oily sludge under the optimization conditions.
