A bacterial lipopolysaccharide emulsifier.
When Acinetobacter sp. was grown in a variety of carbon sources such as alcohols, vegetable oils or hydrocarbons, exolipopolysaccharide was produced. Discussed in this report are the optimal conditions for the production of this exolipopolysaccharide, including different carbon sources, nitrogen sources, divalent magnesium ion, and the addition of antibiotics. The content of the exolipopolysaccharide was assayed by emulsification turbidimetry. The investigation indicated that this exolipopolysaccharide exhibited a good emulsifying ability and emulsion stabilizing activity. It is a polymeric bioemulsifier.
