Outline of Final Research Achievements

Molecular functions of enzymes involved in the decomposition of plant components such as cellulases and hemicellulases have been elucidated by using biochemical analyses on enzymes from isolated microorganisms. However, little knowledge has been revealed about plant decomposition by various microorganisms in the natural environment. Therefore, in this study, we try to clarify plant decomposition mechanisms by conducting biochemical analysis on the enzymes in the natural environment.

Academic Significance and Societal Importance of the Research Achievements

植物細胞壁の主要な高分子成分（セルロース・ヘミセルロース・リグニン）の分解酵素については、腐朽木材から単離された菌を試験管内で培養・単離・解析することで検証されてきた。一方で環境中で実際に働いている酵素についての理解は不十分であった。そこで本研究では、これら自然環境下での木材分解酵素を対象として、酵素を生化学的に解析し、多様な微生物が関与する分解酵素の一部を明らかにした。
