Abstract: | Response surface methodology (RSM) was employed to optimize culture medium for production of lipase with Candida sp. 99-125. In the first step, a Plackett–Burmen design was used to evaluate the effects of different components in the culture medium. Soybean oil, soybean powder and K2HPO4 have significant influences on the lipase production. The concentrations of three factors were optimized subsequently using central composite designs and response surface analysis. The optimized condition allowed the production of lipase to be increased from 5000 to 6230 IU/ml in shake flask system. The lipase fermentation in 5 l fermenter reached 9600 IU/ml. |
