- 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 produced more than 2 g schizophyllan/L. Two strains, ATCC 20165 and CBS 266.60, produced more than 10 g schizophyllan/L. Schizophyllan from these strains was similar to commercial product in terms of solution viscosity, molecular weight, and surface tension properties, suggesting that they would be equivalent in biomaterial applications.
