O-603 カドミウムを高濃度に吸収した稲わらからのバイオエタノール生産とカドミウムの分離(セッション6:震災復興)

抄録

Phytoremediation is an emerging technology, which uses plants to remove pollutants from contaminated sites. In this study, bioethanol production and cadmium removal from phytoremediation plant was investigated. We used the rice straw (Oryza sativa L.) for the remove of cadmium from contaminated sites. Oryza sativa L. was contained 80 ppm of cadmium after phytoremediation treatment. When Oryza sativa L. was treated by 2% of sulfuric acid and enzymes, 75% of sugar yield and 90% of cadmium release were achieved. Furthermore, production of bioethanol from rice straw by simultaneous saccharification and fermentation (SSF) using Schizosaccharomyces japonicus was investigated. 16 (g/L) of bioethanol was produced.
