NOVEL CELLULASE ENZYMES AND SYSTEMS FOR THEIR EXPRESSION

摘要

The present invention relates to the cloning and high level expression of novel truncated cellulase proteins or derivatives thereof in the filamentous fungus Trichoderma longibrachiatum. Further aspects of the present invention relate to fungal transformants that express the novel truncated cellulases and derivatives, and expression vectors comprising the DNA gene fragments or variants thereof that code for the truncated cellulases derived from Trichoderma longibrachiatum using genetic engineering techniques.
