A marine bacterium which was isolated from the enrichment culture for the emulsification of Bunker-C oil produced a bioemulsifier potently. The strain identified as an Achromobacter sp. M-1220. The bioemulsifier was produced during mid-logarithmic phase in hexadecane oil medium at 18$^{\circ}C$. It appeared to be a cationic peptidolipid substance and showed an active stabilizing effect on the emulsion of crude oils and a few vegetable oils.
