Mutarotation of Hydrolysis Products by Different Types of Exo-Cellulases from Trichoderma viride

Abstract
Mutarotation of products from p-nitrophenyl β-D-cellobioside and cellopentaitol by two different types of exo-cellulases from Trichoderma viride was investigated. It was found that an exo-cellulase of glucosidase type produced from the former substrate D-glucose which was mutarotated in a downward direction, while another exo-cellulase of Avicelase type produced from the latter substrate cellobiose which was mutarotated in an upward direction.
