S. thermophile [Myceliophthora thermophila] and A. fumigatus were cultured at 30 and 45 degrees C, respectively, on Emerson's YpSs medium + one of 5 cellulosic substrates: sugarcane bagasse, paddy straw, filter paper, newspaper and cotton. Degradation, as measured by weight loss, was greatest for paddy straw and least for cotton. Activities of 3 enzymes (FPase, CMCase and beta -glucosidase) were measured after 15 and 30 days. Enzyme activities differed with substrate, fungal species and culture time. With sugarcane bagasse, enzyme activity in M. thermophila was greater after 15 days than after 30 days, but in A. fumigatus it was greater after 30 days (except for beta -glucosidase).
