It is economic and environmental to produce ethanol from cellulose, which is the most abundant regenerated resources in the world. Cellulosic saccharification and ethanol fermentation are two important research parts in the bioconversion of cellulose to ethanol currently. This research was about the breeding ofβ-glucosidase-producing strains, the optimum condition of SSF for enhancing hydrolytic efficiency and ethanol yield and the mix-cultured of Penicillium decumbens JU-A10 with Aspergillus aculeat...
