摘要
确定了假单胞菌L-11用葡萄糖为底物产生生物表面活性剂的最适发酵培养基组成和发酵条件。在1L的发酵罐中,L-11的发酵液（10％）与原油的界面张力可以达到5.3×10-3mN/m。该产品可以用于微生物提高原油采收率的实验研究。对其放大工艺也进行了初步的研究。
A strain of pseudomonas sp. L-11 could produce biosurfactants by use of glucose as substrate. The fermentation conditions in shaking flask and 1L fennentor were investigated. The optimal medium and (he fermentation technology were demonstrated. In 1L fermentor, the interracial tension between the diluent of L-11 (10%) and crude oil is 5.3×10~3mN/m, which is fit for microbial enhanced oil recovery. The scale-up technology of L-11 was also studied.
