Cellulase production by fermentation with trichoderma viride on cellulose and wood wastes
<p>"Cellulase production by the fungus Trichoderma viride QM 6a and the use of this cellulase for cellulose hydrolysis were studied using Solka Floc cellulose and waste wood (oak) as substrates. The fermentation produced higher enzyme concentration solutions with media containing additional amounts …
