This procedure yielded a fungal strain that we named TG2. TG2 had similar growth, but significantly higher levels of cellulolytic enzyme activities than T. reesei RUT-C30 (Fig. 1), a major commercial strain used for production of cellulolytic enzymes. Consistent with these initial results on solid media, cultivation in a liquid medium with 1% glucose as a substrate, indicated that TG2 had higher activities of endoglucanase (2.0-fold greater), exoglucanase (1.7-fold greater), and b-glucosidase (4.0-fold greater) than T. reesei RUT-C30 (Fig. 2).
