We examined the production profile of cellulolytic enzymes by
Penicillium sp. TG2 in experiments that used 5% cellulose as the
substrate. The results indicate that the activities of endoglucanase
and exoglucanase were maximal at 2 days of culture, and then
decreased dramatically. FPase had a similar profile. However, bglucosidase
activity was maximal at 4 days of culture. The maximal
and specific activities were 1.27 U/mL and 2.28 U/mg for endoglucanase,
0.31 U/mL and 0.56 U/mg for exoglucanase, 0.54 U/mL and
1.03 U/mg for b-glucosidase, and 0.45 U/mL and 0.81 U/mg for
FPase (Fig. 3)
