| Research Abstract |
The purpose of this study is to use the microbe that grows under low-nutrition and to make a woody biomass a useful resource. A number of yeast were isolated that used woody biomass as the only carbon source. Then, this research conducted decomposition and assimilation experiment of the biomass by the yeast for the purpose of effective use of the unutilized biomass. The grown yeast is reused as the sources of nutrient, such as vitamin and a mineral. This research result contributes to the new method of biomass effective utilization.
The yeast were inoculated to the mineral salt liquid medium which added the biomass as the only carbon source, and long-term culture were performed. It was clear that the powder type of the straw was more easily degradable than the solid type of that. The powder type of the straw was cultured for long term. These results point out the possibility that the yeast which can be grown under low-nutrition can transform woody biomass into effective resource.
