Abstract
Recent studies show the potential impacts of insect symbiont microbes on biofuel application with regard to their degradation capability of a recalcitrant plant cell wall. In this study, we describe a novel fungal isolate, D. decipiens oita, as a single symbiotic fungus from the Xiphydria woodwasp found in the northern forests of Japan. Our detailed secretome analyses of D. decipiens oita, together with activity measurements, reveal that this insect-associated fungus exhibits high and broad activities for plant cell wall material degradation, suggesting potential applications within the biomass conversion industry for plant mass degradation.
