从石油污染土壤中分离到一株新的细菌，经鉴定命名为铜绿假单胞菌LBI。该菌株以皂脚为唯一碳源，在无机盐培养基中分批培养，产生具有表面活性的鼠李糖脂。生物表面活性剂的生产增加后，氮耗尽。当在生物反应器中以169.9 h（-1）的常数K（L）a孵育时，达到最大鼠李糖脂浓度15.9 g/l。(C)2002爱思唯尔科技有限公司。保留所有权利。
A new bacterial strain, was isolated from petroleum contaminated soil, identified and named Pseudomonas aeruginosa strain LBI. The new strain produced surface-active rhamnolipids by batch cultivation in a mineral salts medium with soapstock as the sole carbon source. Biosurfactant production increased after nitrogen depletion. The maximum rhamnolipid concentration, 15.9 g/l, was reached when it was incubated in a bioreactor with a constant K(L)a of 169.9 h(-1).
