摘要: Food waste generated in Korea is rich carbohydrate as high 65% of total solids. Using the food waste, feasibility ethanol production was investigated a lab-scale fermentor. Pretreatment with hydrolyzing enzymes including carbohydrase, glucoamylase, cellulase and protease were tested for hydrolysis waste. The carbohydrase able to hydrolyze produce glucose yield 0.63 g glucose/g solid. Enzymatic fermentation by using Saccharomyces cerevisiae conducted batch mode. For separated (SHF), concentration reached at level corresponding an 0.43 ethanol/g simultaneous saccharification (SSF), 0.31 During continuous operation SHF, volumetric rate 1.18 g/lh 0.3g SSF process, 0.8 0.2g
