Discovery of Novel Cellulases Using Proteomic Strategies
In order to develop cost-effective processes for conversion of lignocellulosic biomass, discovery of novel enzymes for enhanced lignocellulose hydrolysis is one of the main scientific and industrial goals. This could be achieved by applying proteomic strategies for identification of proteins secreted by filamentous fungi that are among the most powerful producers of biomass-degrading enzymes. Here a strategy for a comparative study of proteins differentially secreted on media inducing production of biomass-degrading enzymes (e.g., lignocellulosic biomass) and media repressing secretion of those enzymes (e.g., glucose) are presented. The protocols presented include preparation of samples for mass spectrometry and identification of cellulolytic and other carbohydrate-degrading enzymes using bioinformatics.
