Abstract
Cellulose is the most abundant organic raw material in the world,and it is the only renewable resource that is available in large quantities.Currently,only a few cellulose are utilized,most of cellulose are wasted and polluted environment.Therefore,finding a way to utilize the cellulose to solve the problem of food shortage and energy crisis by microorganism will have a significant influence on our life.Enzymolysis of cellulose is a complex biochemical process,its mechanism had been studied for many years.Its mechanisms had a various hypotheses.Three main theories being widely accepted are:Synergism,Initial degrading and Fragmentation.The optimal saccharification condition of rice straw powder by cellulose in this paper was obtained by the single factor experiment:rice straw powder was pretreated by1.0%NaOH+1.0%H2O2,substrate concentration was 2.5%,saccharification temperature was 50℃,saccharification pH was 4.8,and ratio of filter paper enzyme/β-glucosidase was 1 : 1.关键词
