Effective utilization of the woody biomass using the microbe which can be grown under low-nutrition.

本研究的目的是利用在低营养条件下生长的微生物，使木质生物质成为有用的资源。分离出许多使用木质生物质作为唯一碳源的酵母。很显然，粉末状的吸管比固体状的吸管更容易降解。对秸秆粉料进行长期培养。在培养前后，用SEM（扫描电子显微镜）检查秸秆表面状况的变化。这些结果表明，在低营养条件下生长的酵母菌有可能将木质生物质转化为有效资源。

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. 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. Before and after incubation, changes of the surface condition of the straw were examined with the SEM (scanning electron microscope). These results point out the possibility that the yeast which can be grown under low-nutrition can transform woody biomass into effective resource.
