Abstract
The biodegradation of hydrocarbon contaminated water is enhanced by the adding to the contaminated water a hydrocarbon solution of (a) a mixture of a sorbitan ester of a C.sub.7 to C.sub.22 monocarboxylic acid and a polyoxyalkelene adduct of a sorbitan ester of a C.sub.7 to C.sub.22 monocarboxylic acid, the adduct having from 4 to 50 polyoxyalkelene units, (b) an alkyl glycoside wherein the alkyl group has from about 8 to 18 carbon atoms and the gylcoside is a mono or diglycoside, or a mixture thereof, in amounts sufficient to promote the growth of indigenous microorganisms. In another embodiment of the invention a source of microbial assimilable nitrogen and phosphorous also is supplied to the contaminated water.
