Much attention has been focused on bioethanol production from cellulosic biomass instead of corn and sugarcane. Dilute sulfuric acid method has been installed for treatment of construction waste wood in Sakai, Osaka. Enzymatic hydrolysis is a promising technology for bioethanol production from cellulosic biomass in near future. Enzymatic method required effective pretreatment method. AIST biomass technology research center is conducting studies on mechano-chemical pretreatment, enzyme production with fungi, and genetic engineering of yeast for xylose utilization. We found that wet disk milling was low energy consuming pretreatment for wood. We also developed a high cellulase producing mutant fungi of Acremonium cellulolyticus and fast xylose converting diploid yeast by genetic engineering.
