In Japan T. viride is a harmful mold to Shiitake mushroom (Lentinus edodes) during log wood cultivation. Shiitake mushroom is killed with T. viride grown on log wood. The stroma of Hypocrea, perfect stage of T. viride is produced on log wood. In the course of investigation of T. viride cellulase, the author found that the mycelia of Shiitake, Aspergillus niger and Saccharomyces cerevisiae were degraded or dissolved with T. viride wheat bran Koji extract or commercial cellulase preparation derived from T. viride.The mycelia of Shiitake and A. niger consist mainly of chitin and beta-1,3-glucan, while cell walls of yeasts include beta-1,3-glucan as a substantial constituent. Recently the author found that the extract of a Koji prepared by using air-dried Shiitake mushroom according to wheat bran Koji process showed a remarkable mycolytic, but only a little cellulolytic activities. A new Koji process for production of T. viride mycolytic enzyme was developed using starch pulp in place of Shiitake as a supporting medium.The optimum pHs of beta-1,3-glucanase and chitinase activities in T. viride Shiitake Koji extract were shown to be 5.0.A potent T. viride mycolytic enzyme could be produced by using sweet potato starch pulp including a small amount of Shiitake mushroom or of a feed yeast (Candida utilis). A submerged culture process for T. viride mycolytic enzyme production using a synthetic medium and a feed yeast was also developed. The degradation of Shiitake mushroom, compressed baker's yeast, a feed yeast, Asp. niger pellet and a glutamic acid producing bacterium with T. viride mycolytic enzyme were observed.
