Effects of Foreign Substances on Esterase Production of Solid-State Fermentation by Monascus

Abstract:

In this manuscript,Monascus HQ-3 was used as the experimental strains to produce esterase by the solid-fermentation.The effect of nutrient substances addition on the esterase production were investigated.The result show that glucose used as rapidly-efficient carbon source and fresh yeast lysate as nitrogen source for esterase production.After 4 d fermentation,the esterification force was 1.30 times higher than that of the control group.It had certain effect to improve esterification force by adding appropriate amount of lactic acid et al material,which was obviously by adding ethanol.
