Several organisms tested, including Sclerotium glucanicum NRRL 3006 and Helotium sp. NRRL 3129, were able to make high viscosity glucan polymers from the hydrolysis products of naturally occurring lignocellulosic materials. Hydrolysis of the tested materials was accomplished by swelling in mild alkali for a 24-h period followed by hydrolysis in mild acid for a 30-min period at 121 C. The medium used for polymer production consisted of hydrolyzed lignocellulosic materials, salts, and a trace of yeast extract. Starch also was used as a fermentation feedstock, but was not hydrolyzed. The fermentations were performed over 4- or 5-day periods.
