Bioethanol Production from Various Plant Materials via Solid-state Fermentation

Previously, we have reported a novel bioethanol production system based on solid-state fermentation (SSF) and forage rice, which is used in silage-making process. In this study, evaluated the productivity of valuable materials via SSF using various plant other than rice. Italian ryegrass, sorghum, cassava, are also promising for SSF. Laboratory-scale experiments raw ryegrass yielded maximum 99 mg/g dry matter ethanol (organic acids soluble sugars). The conversion rates were almost same as that nutritional value fermented products livestock feed either improved or was similar to silage.
