Updated project metadata. The project compares the genomes of multiple Aspergillus species. In particular, the genes involved in the degradation of plant-derived biomass have been analyzed. As well, the extracellular proteins produced by the fungi during the utilization of sugar beet pulp and wheat bran were examined by LC-MS/MS. Results show that closely related species can deploy different enzyme mixtures in the hydrolysis of plant-derived biomass. These results imply that efficient hydrolysis of biomass can be achieved by combining enzyme mixtures from two or more fungi.
