串珠霉利用稻草产纤维素酶的研究

Studies on cellulase produced by Monilia using straw

纤维素酶是一类可以将纤维素水解成葡萄糖的酶,其利用对人类可持续发展具有非常重要的意义。本文对串珠霉利用稻草产纤维素酶的工艺条件进行了一系列优化实验,最终得出最佳产酶条件为:稻草粉6%,麸皮3%,豆饼粉3%,玉米粉2%,KH2PO40.5%,CaCl22.03%,pH 4.5,接种量3mL,28℃,发酵7天。

Cellulase can convert cellulose to glucose,so it has great realistic meaning for sustainable human development.The optimum fermentation conditions of Monilia is following： straw powder6%,bran3%,bean powder3%,corn flour2%,KH2PO40.5%,CaCL22.03%,pH 4.5,28℃,fermentation period 7days,inoculation size 3mL.
