beta-Glucosidase in cellulosome of the anaerobic fungus Piromyces sp. strain E2 is a family 3 glycoside hydrolase.

The cellulosomes of anaerobic fungi convert crystalline cellulose solely into glucose, in contrast with bacterial cellulosomes which produce cellobiose. Previously, a beta-glucosidase was identified in the cellulosome of Piromyces sp. strain E2 by zymogram analysis, which represented approx.
