Abstract

The physiological basis for the inhibition of P. flabellatus growth by S. [Corticium] rolfsii was examined. Growth rate of C. rolfsii in vitro was greater than that of P. flabellatus at 20, 25, 30 and 32C. C. rolfsii could degrade cellulose and hemicellulose, and showed higher rates of cellulolytic and hemicellulolytic activities per unit time incubation of straw, compared with P. flabellatus. While the carboxymethyl cellulose (CMC)-ase and hemicellulase activities of P. flabellatus were inhibited at pH 3.2, C. rolfsii is known to demonstrate significant activities of these enzymes at pH as low as 2.0. C. rolfsii produced high amounts of oxalic acid compared with P. flabellatus.
