Screening of Fungi Producing Cellulase and Its Degradation on Straw

The strains which could produce high activity cellulase had been chosed,so the straws could be degraded into things that were good for the environment.Then the strains could be used in our lives.Method:Because of the proportion to the diameter of transparent ring and the diameter of the strain,we chose the strains NO.1 and NO.2.Solid fermentation method was used to culture the two strains,then we detected the enzyme activity.It was true that the enzyme activities of the two strains were all very high.Results:The two strains were cultured for 3 days,in this condition,the highest enzyme activity of the strains were 278.35 IU/g and 274.39 IU/g,respectively(P0.05).The highest degradation rate of No.1 and No.2 on cellulose and hemicellulose were 16.18%,52.45% and 14.89%,45.31%,respectively.There wasn′t degradation of No.1 and No.2 on lignin。
