Interpretive Summary: Practical new methods are needed to produce value-added products from low-value agricultural residues such as corn fiber. We discovered a simple bioconversion method to produce two valuable carbohydrates from corn fiber. This work will be of interest to researchers developing new uses and value-added products from agricultural commodities and byproducts.

Technical Abstract: Schizophyllum commune strain ATCC 38548 grew well on a medium containing alkaline hydrogen peroxide-pretreated corn fiber as a sole carbon source, and clarified the culture medium within seven days. The strain preferentially utilized the starch component of corn fiber for growth and production of schizophyllan. Culture supernatants contained good yields of both schizophyllan and arabinoxylan from corn fiber. These polysaccharides were recovered separately by differential precipitation with ethanol.
