A method for the biodegradation on an oil-based sludge comprising a mixture of petroleum hydrocarbons is disclosed. The method comprises forming an aqueous solution in a reactor of an oil-in-water emulsion of the oil-based sludge, bacterial culture and nutrients for the bacterial culture, the bacterial culture having the ability to grow on petroleum hydrocarbons as sole carbon source and having been isolated from a hydrocarbon contaminated soil or hydrocarbon-containing sludge or other environments rich in hydrocarbon degrading bacteria, maintainingthe aqueous solution under aerobic conditions in the reactor at a temperature of at least 10&deg; C. for a period of time sufficient to reduce the amount of hydrocarbon by at least 25%, and discharging aqueous solution having a reduced amount of hydrocarbons from the reactor. The method may be used on sludge containing aromatics, resins and asphaltenes.
