| Outline of Final Research Achievements |
White-rot fungi, a kind of wood decaying fungi are able to produce ethanol from wood during incubation under low oxygen conditions with some nutrients supplementation. Ethanol fermentation properties from wood of some white-rot fungi was investigated, and only Phanerochaete sordida showed reproducible ethanol production from wood withtout any nutrients. From detail studies of the fermentation property of this fungus in nutrient medium, it was suggested that this fungus produces ethanol due to overflow in sugar metabolism under aerobic conditions, and that the improvement of sugar uptake of the fungus lead higher ethanol production via carboncatabolite repression. On the other hand, it was appeared that P. sordida probably utilizes their ethanol fermentation as a short-term resistance system to hypoxic stress during wood decay.

| Academic Significance and Societal Importance of the Research Achievements |
食料と競合しないバイオマスである木材などのリグノセルロースバイオマスの利用法の確率は、持続可能社会の構築において重要である。白色腐朽菌は、リグノセルロースバイオマスからのバイオエタノール産生を、単一微生物かつ単一容器内で行うことができる微生物である。本研究成果によって、この様な特性を持つ微生物のエタノール産生機構の一部が明らかになり、今後の白色腐朽菌を用いたリグノセルロースバイオマスからのエネルギー生産技術開発の一助となる基礎的知見が得られた。
