Abstract:
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.
