Abstract

Schizophyllum commune strain ATCC 38548 grew well on a medium containing alkaline H2O2-pretreated corn fiber as a sole carbon source, and clarified the culture medium within 7 days. The strain preferentially utilized the starch component of corn fiber for growth and production of schizophyllan. Culture supernatants contained approx. 50 mg schizophyllan and 200 mg arabinoxylan per g corn fiber. These polysaccharides were recovered separately by differential precipitation with ethanol.
