Abstract
The fungus Trichoderma reesei grows on barley (Hordeum valgare L.) beta-glucan and pachyman, secreting increased quantities of exo-beta 1,3-glucanase. This enzyme is also found in commercial cellulase preparations, from which it has been partially purified. It has a mol.wt. of 700000, an isoelectric point of 4.2, is cold-stable and hydrolyses both beta 1 Leads to 3- and beta 1 Leads to 6-linkages.
摘要
里氏木霉可在大麦（Hordeum valgare L.）β-葡聚糖和茯苓聚糖上生长，并分泌出更多的外切β-1,3-葡聚糖酶。这种酶也存在于商业纤维素酶制剂中，并已从中部分纯化出来。它的分子量为700000，等电点为4.2，具有冷稳定性，可水解β-1,3-和β-1,6-糖苷键。
