Abstract: This work reports the application of response surface methodology based on a three-variable, three-level Box-Benhnken design to optimize fermentation parameters to enhance the production of erythritol from molasses and corn syrup using yeast RH-UV-L4-F9, a potent erythritol producing strain. The optimal values of temperature, pH and shaking speed were 32.3 ℃, 5.1 and 176 r/min, respectively. Under the optimized conditions, the yield of erythritol was 166.89 mg/mL, which was 1.2-fold higher than before the optimization.

Key words: erythritol, response surface methodology, fermentation, optimization
