Cellulolytic and hemicellulolytic enzymes functional above 100℃

Abstract

Cellulases and hemicellulases have a variety of potential industrial applications, including the production of fermentable sugars from biomass and enzyme-assisted pulp bleaching. There are several advantages, in industrial terms, to be gained from employing thermostable enzymes in processes operating at elevated temperatures. For example, the lignin component of hemicellulose, which often blocks enzyme access, softens and melts over the temperature range 90-180°C.
