P-45 セルロースを用いた同時糖化発酵(SSF)と糖化発酵分離方式(SHF)の特性(セルロースエタノール,Poster Session)

抄録

Cellulose was treated by simultaneous saccharification and fermentation (SSF) and separate hydrolysis and fermentation (SHF). In SSF enzymatic hydrolysis and fermentation was performed in the same reactor. In SHF hydrothermal treatment, enzymatic treatment and fermentation were conducted in three steps. Cellulose powder was employed as feedstock, and reaction was conducted at 30, 35, and 40 ℃. The concentration change of glucose was mostly the same when for temperature was changed from 30 to 40 ℃. At 30 ℃, the highest ethanol concentration was obtained for both SSF and SHF.
