IPC: C12R1/72
Filed: 2000-08-04
Abstract: PROBLEM TO BE SOLVED: To provide a fermentation production method in which residual oil and fat in culture solution after finishing fermentation is slight and sophorose lipid is produced in a high yield, and provide a culturing method capable of utilizing an inexpensive raw material as a culture medium. SOLUTION: In this fermentation production method, an yeast of the genus Candida which has been known as sophorose lipid-producting live germ hitherto is used and a fatty acid is mixed with a vegetable oil or waste edible oil as an oily substrate adding to liquid culture medium. Thereby, sophorose lipid production amount and yield is increased and culturing period is shortened and oil and fat amount left after culturing is remarkably reduced compared with the case when fatty acid is not added. The above method simply enables purifying sophorose lipid in large amount from culture solution and can inexpensively carry out fermentation production by utilizing the waste edible oil.
