Supplementary Material

Tables S1 to S6 are statistical information used and generated while optimizing process conditions for better SK production by Saccharomyces cerevisiae. Table S1 and S2 are the design matrix for screening carbon and organic nitrogen sources by using Placket-Burmun design. Experiments were conducted according to the design matrix and results are used in subsequent optimization studies. Table S3 is the range and levels of four variables considered for optimization. Table S4 is the design matrix generated according to central composite design for response surface methodology. Table S5 and S6 are ANOVA of quadratic equation and responses multiple linear regression analysis respectively.
