红曲霉酯酶酯化特性的探讨

Exploration to the esterification property of esterase produced by Monascus spp.

酯酶是分解催化脂肪中酯键的酶类,具有水解或合成的能力,烟灰色红曲霉产生的酯酶活性较高。该文对1株烟灰色红曲霉所产酯酶进行了酯化特性的探讨,结果表明:该红曲霉酯酶的最适催化温度为40℃,最适催化酒精度为12%(v/v),最适催化pH为3.0,且该红曲霉酯酶属于键专一性的生物酶。

Esterase is a kind of enzyme, which decompounds and catalyses ester bonds, and has the ability to hydrolyze and synthesize the ester. Esterase produced by Monascus fulginosus has higher activity. In this paper, we made exploration to the esterification property of the esterase produced by Monascus fulginosus . The results indicated that the optimal catalyze temperature was 40℃,the optimal alcohol degree was 12%(v/v), the optimal pH value was 3.0, and the Monascus esterase is a bond specificity biology enzyme.
