Dissecting the Pathway to Hyper-Secretion of Lignocellulolytic Enzymes in Filamentous Fungi

Filamentous fungi degrade most plant material, especially lignin and cellulose. The ultimate goal of this program is to understand the genomic and secretory pathway remodeling that occurs when Neurospora crassa deconstructs plant cell walls/cellulose in order to use rational design to create these industrial strains that secrete high amounts of those enzymes, cellulases and hemicellulases.

2011 Highlights

The Glass group screened more than 200 mutants and are characterizing about 20 strains with altered enzyme activity or growth on cellulose. They also designed tools to probe the secretory pathway that may yield methods to increase cellulolytic enzyme output. PI's Cate and Glass have also been developing a protein expression system to generate engineered fungal cellulases for industrial use.

2010 Highlights

Glass’s lab has developed a number of cell biological tools that enable live cell imaging of components of the secretory apparatus during secretion of cellulases/hemicellulases.
