| Outline of Final Research Achievements |
A few wood-decaying basidiomycetes isolated from nature produced ethanol from xylose, glucose, mannose, cellobiose, and maltose with relatively high yields. The white rot fungus Trametes versicolor was capable of directly fermenting various types of starches, including corn, potato, rice, and wheat starches. The fungus also directly converted untreated kitchen waste to ethanol in the absence of externally added enzymes or nitrogen. Our findings indicate that T. versicolor efficiently hydrolyzes biomass to fermentable sugars and directly converts them to ethanol, and may permit cost-effective and environmental friendly bioethanol production from various starting materials, including kitchen waste.
