| Outline of Final Research Achievements |
Utilization of rice straw, which is one of lignocellulosic biomass, was aimed. As the pretreatment, mechanical milling of rice straw increased subsequent production of methane or ethanol by microorganims. (Energenic consumption using mechanical milling was low.)
Liquid fraction of hydrothermally pretreated rice straw was concentrated by nano-filtration (NF) membrane. Enzymatic hydrolysis of this concentrate precipitated lignin easily.
Ultra-filtration permeation and NF concentration were performed on the sweet sorghum juice. Saccharomyces cerevisiae repeatedly produced about 100 g/L of ethanol from the NF concentrate.
