| Outline of Final Research Achievements |
To elucidate the mechanism of biomass degradation in nature, hemicellulose degradation by actinomycetes, which is involved in early biomass degradation, and by basidiomycetes, which is involved in late biomass degradation, was investigated. The gene clusters were analyzed to identify the enzymes involved in the carbohydrate hydrolysis family classification. We analyzed gene clusters and found the most important operon in the xylan degradation of Streptomyces olivaceoviridis. The properties of xylanase and arabinofuranosidase, which have not yet been elucidated, were clarified. Single molecule observation of the xylanase of this fungus was also carried out. The properties of the xylanases of the basidiomycetes were clarified, and a comparison was made with those of the xylanases of the actinomycetes.
