Project Details

Abstract

Ethanol-fermenting fungi Mucor javanicus J has strong ethanol fermentation ability from pentose under aerobic condition. To clarify this phenomenon and the pentose metabolic pathway, the metabolism flow from xylose to ethanol was ascertained by the metabolome analysis by CE-TOFMS. To improve the cellulolytic enzyme secretory response of the bacterium share, The fungus with high ability to secrete endo-β-glucanase was screened among our Mucor library and then the fusion cell of the fungus and M. javanicus J was constructed. When CBP with the fusion cell from rice straw prepared alkaline treatment were carried out, 5. 2 g/L of ethanol was able to directly produce.
