As to the available components in the food residue,the ethanol and oil were produced by Alcohol Yeast and Geotrichum robustum with the refuse liquid hydrolyzed by multi-enzyme respectively.Through experiments,the optimum hydrolysis conditions were acquired as follows:8u/g of amylase,200u/g of glucoamylase,50u/g of protease and 50u/g cellulose be added at the same time,pH5~7,50~60℃and the hydrolyzing time for 2h.Inoculated in strains after regulated sugar degree and pH value of enzyme solution appropriately,...
