Improved saccharification of cellulose by cloning and amplification of the Trichoderma reesei beta-glucosidase gene

摘要

A process for expressing extracellular beta -glucosidase in a filamentous fungus by expressing a fungal DNA sequence encoding enhanced, deleted or altered beta -glucosidase in a recombinant host microorganism is disclosed. Recombinant fungal cellulase compositions containing enhanced, deleted or altered expression of beta -glucosidase is also disclosed.
