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.
当不动杆菌属在多种碳源（如醇类、植物油或碳氢化合物）中生长时，会产生胞外脂多糖。本报告讨论了生产这种胞外脂多糖的最佳条件，包括不同的碳源、氮源、二价镁离子以及抗生素的添加。通过乳化比浊法测定胞外脂多糖的含量。研究表明，这种胞外脂多糖具有良好的乳化能力和乳液稳定活性。它是一种聚合生物乳化剂。
