Abstract

A study was done to investigate the enzyme activities of cellulases produced by four fusants of Trichoderma reesei Rut C30 Penicillium funicolosus mg (7) using rice straw as the cellulosic substrate. Statistical analysis shows that there is no significant differences among the cellulase activities of all four fusants when subjected to both carboxymethylcellulose and filter paper assay. Analysis of the specific activities on CMC showed as no significant differences among the fusants means while those on filter paper showed a wide range of enzyme specificities. The enzyme activities of the fusants on both CMC and filter paper assays are higher than the parental strains. This means that their fusion produces enzymes that act comparatively and synergistically with each other for an effective and efficient degradation of cellulose to glucose.
