 This study evaluated the enzymatic potential of a broad range of plant pathogenic and non-pathogenic fungi for their ability to degrade plant biomass and isolated polysaccharides. Plant pathogenic fungi were found to be more active than non-pathogens on six of eight substrates tested, with no significant difference seen on the other two substrates. Additionally, several highly active isolates of plant pathogenic fungi were identified, particularly when tested on silence and untreated biomass. This suggests that these fungi may provide valuable sources of novel cell wall degrading enzymes for industrial applications.
