Abstract

Mutarotation of products from p-nitrophenyl beta-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.

摘要

研究了来自绿色木霉的两种不同类型的外切纤维素酶对对硝基苯基β-D-纤维二糖苷和纤维五醇产物的变旋现象。发现由前一种底物产生的葡糖苷酶类型的外切纤维素酶生成的D-葡萄糖发生向下变旋，而由后一种底物产生的微晶纤维素酶类型的另一种外切纤维素酶生成的纤维二糖发生向上变旋。
