To screen the high yield strain producing esterification enzyme,four strains of monascus were employed to optimize the liquid medium for fermenting esterification enzyme by single-factor test and orthogonal test in the current work.The result showed that the monascus ZK was the best among the four tested strains,with the activity of esterification enzyme 206.4 U·mL-1.The optimal liquid medium for esterification enzyme production contained 70.0g/L-1 soluble starch,25.0 g/L-1protein peptone,2.0 g/L-1NaNO3,and 1.0 g/L-1 MgSO4·7H2O.The average activity of esterification enzyme in optimal medium(293.8 U·mL-1)was 42.3% higher than that in basal medium among four times of constant tests.
