Screening and Identification of Cellulase-Producing Strain of Fusarium Oxysporum

Five strains were screened out from 120 strains of Fusarium Oxysporum Schl. isolated from different regions. Based on ITS analyses, the strains were determined as Fusarium Oxysporum Schl. The strain named as H57-1 produce the highest cellulase, which activity reach at 1.43 IU/mL. The most suitable reactive pH of the CMCase was 4.5∼5.5, and the most suitable reactive temperature is 60∼65°C. Its activity is stable at pH 5.3∼9.5 and 4∼50°C.
