Abstract:
The medium of photo-synthetic bacteria synthesizing carotenoid was optimized with response surface methodology. The regression equation expressing the relationship between carotenoid yield and main components of culture medium was established by stepwise analysis. The R-squared in the model of regression equation was 0. 958, which meant the established equation could predict the carotenoid yield well at the range of factors in this design. It was indicated that the optimum medium components were: 0. 81% citric acid, 0. 35% NH4Cl and 0. 18% corn syrup. On those conditions, it was predicted that the highest production of carotenoid was 13. 34 mg/L, which was 2. 04 times higher than initial carotenoid yield before optimization.
