Schizophyllan is a homoglucan produced by the fungus Schizophyllum commune, with a β-1,3-linked backbone and β-1,6-linked side chains of single glucose units at every other residue. Schizophyllan is commercially produced for pharmaceutical and cosmetics uses. However, surprisingly little information is available on the biodegradation of schizophyllan.(More)

Schizophyllan is commercially produced for pharmaceutical and cosmetics uses. However, the unique physical properties of schizophyllan suggest that it may have biomaterials(More)
An enzymatic method was developed for the progressive modification of the polysaccharide schizophyllan. Fungal strains Hypocrea nigricans NRRL 62555, Penicillium crustosum NRRL 62558, and Penicillium simplicissimum NRRL 62550 were previously identified as novel sources of β-endoglucanase with specificity towards schizophyllan. Concentrated enzyme(More)
Schizophyllan is a biopolymer commercially produced for pharmaceutical and cosmetics uses. However, schizophyllan also has potential biomaterial applications. Schizophyllan is conventionally produced from glucose and recovered by diafiltration and ultrafiltration to produce a highly purified product. Here we demonstrate a simplified process for preparation(More)
Beans are known to be a rich source of antioxidants in foods. In this work, we report our preliminary studies of the use of microwave as a fast method for the extraction of antioxidants from beans. Antioxidant capacities of the extracts from cotyledon and hull of eight common beans were determined, using the β-carotene bleaching method. Microwave-assisted(More)
Eleven diverse strains of Schizophyllan commune were examined for production of the biopolymer schizophyllan from agricultural biomass. Strains were grown in malt extract (ME) basal medium containing 1% (w/v) distiller's dried grains with solubles (DDGS), an abundant coproduct of fuel ethanol production by the dry grind process. Ten of 11 strains tested(More)
