Open full text 35 citations

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.
