Abstract
Growth of Acinitobacter Sp. ATCC 31012 on certain substrates produces a new class of extracellular microbial protein-associated lipopolysaccharides (the '.alpha.-emulsans'). .alpha.-Emulsans exhibit a high degree of specificity in the emulsification of hydrocarbon substrates which contain both aliphatic and aromatic or cyclic components, which are typical of the hydrocarbonaceous residues found in oil-contaminated vessels, such as tankers, barges, storage tanks, tank cars and trucks, pipelines and other oil-contaminated containers used to transport or store crude oil in petroleum fractions. These oil-contaminated vessels may be cleaned by washing the oil-contaminated surfaces of such vessels with an aqueous solution in sea water or fresh water containing from about 10 mcg/ml to about 20 mg/ml of .alpha.-emulsans and from about 5 mM or higher of at least one divalent cation, thereby forming an oil-in-water emulsion of such hydrocarbonaceous residues from which the oil may be recovered for fuel value or for refining.
