[ Method ] Morphologic observation and sequence analysis of 18S rDNA were conducted. [Result] A cellulase-preducing strain with high activity was obtained, and morphology of the strain was highly similar to that of Trichoderma reesei. Results of sequence analysis show that the 18S rDNA sequence shares 99% homology with Hypocreajecorina. [ Conclusion] The isolated cellulase-producing strain belongs to Trichoderma reesei.展开更多
