Sophorolipid has been shown to be one of the most productive microbial biosurfactants. However, it is difficult to implement in industrial applications because the production cost is higher than that of general surfactants. In this study, we chose the most productive oils to produce sophorolipid and compared their productivities in relation to different
concentrations of glucose. The findings show that tested rape seed oil had the highest productivity of the sophorolipids. The concentration of glucose in rape seed oil was 30g/l. Fed-batch method was conducted using Candida bombicola ATCC 22214, by rape seed oil as a secondary substrate. Feeding rate of rape seed oil, was depended on decreasing
pH and glucose concentration was constantly maintained between 30 and 40(g/l). As a result, we have produced a crude sophorolipid up to 365g/l for 8days.
