Abstract
The fungus T. reesei grows on barley (Hordeum vulgare L.) .beta.-glucan and pachyman, secreting increased quantities of exo-.beta.1,3-glucanase. This enzyme is found in commercial cellulase preparations, from which it has been partially purified. It has a MW of 70,000, an isoelectric point of 4.2, is cold-stable and hydrolyzes both .beta.1 .fwdarw. 3- and .beta.1 .fwdarw. 6-linkages.
