Abstract

A study was done to compare the activities of cellulases produced by three Penicillium strains previously expose to ultraviolet radiation for 50, 150 and 250 minutes, respectively and that the parental strain. Statistical analysis showed that the four strains have no significant differences in their carboxymethylcellulase (CMC-ase), B-glucosidase and filter paper activities Nevertheless, slightly higher activities of B-glucosidase and CMC-ase observed in uv irradiated strains compared to that of the parental strain. Avicelase activity though very minimal was shown to significantly increase in the other strains. all the other three strains had almost zero activity. All the other three strains had almost zero activity. Filter paper activity, like the avicelase, had almost zero activity for the irradiated strains and an minimal activity in the parental strain. Aside from uv irradiation, other factors like amount of initial inoculum in the culture medium for cellulase production, incubation temperature and crude enzymes extract preparation can effect growth of organism and cellulase activity.
