| 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.
