Outline of Final Research Achievements

In this study, we attempted to develop the efficient production process of not only biofuels but also biobased materials from lignocellulosic biomass using a high activity steam treatment. The simultaneous saccharification, fermentation and detoxification SSDF process of steam-exploded cedar using Meicelase, Saccharomyces cerevisiae BA11, and a detoxification microorganism, Ureibacillus thermosphaericus A1 was carried out for bioethanol production. A fed batch SSDF culture, in which U. thermosphaericus A1 was used to maintain low concentrations of inhibitory materials, was effective for increasing the ethanol concentration. The conversion of lignocellulosic biomass into useful biobased materials was also studied for the effective utilization of its components. The holocellulose, water soluble material, and organosolv lignin could be converted into useful materials, i.e. cellulose nanofiber, antioxidant material, and lignin epoxy resin, respectively.
