| 英文摘要 | a consolidated bioprocess integrating enzyme production, saccharification and fermentation was applied for bioethanol production. mixed solid-state fermentation of alkali-pretreated sugarcane bagasse (scb) supplemented with wheat bran (wb) to produce a compound enzyme for saccharification by trichoderma and penicillium was carried out, and at 72 h, the obtained sugars concentration was 20.190 g/l. then the mixture was further converted to ethanol by inoculating saccharomyces cerevisiae. after 24 h, the maximum ethanol concentration 5.825 g/l (40.84% of theoretical yield) was achieved. at 144 h, the produced 8-glucosidase activity and fungal biomass were 0.483 iu/ml and 0.204 g/g, respectively. the consolidated bioprocess avoided enzyme preparation, saved much water/energy consumption and reduced equipment investment, which indicated that it might be an effective approach for the economic production of bioethanol.
