Abstract
C. cellulolyticum is the best organism for upgrading the protein values of corn stover in solid state fermentation. It grew profusely on the surface, intercellularly and intracellularly in alkali-treated substrate. The hyphae entered into the cell lumen through natural openings, mechanical breaks or spaces (created by solubilization of hemicelluloses and lignin during alkali-treatment) in the cell wall of the substrate tissue. Once inside the cell lumen, the hyphae digested the cell wall starting from inside towards the outside. Ultimately, the whole cell wall was utilized. The protein values of corn stover were increased from 6.5 to .apprx. 24% within 5 days of fermentation.
