- 論文の詳細を見る
A pilot-scale solid-state ethanol fermentation system was experimented on, using corn grits. The ethanol produced was simultaneously stripped in the fermentor by circulating CO_2 gas. Using a moderately thermophilic yeast (Saccharomyces cerevisiae 1031R) at a fermentation temperature of 40℃, the stripping efficiency was improved and running time was shortened. In this case, 467 g-ethanol/kg-initial dry mass was produced during 15 d of running. Fermentation efficiency was 87%, which is twice as much as conventional solid-state ethanol fermentation. The total racovery of ethanol produced was 96%, and the average ethanol concentration in the condensate was 223 g/l.
