P213 Effects of Hot Compressed Water Treatment with Phosphoric Acid for Enzymatic Saccharification of Rice Straw

Abstract

Hot compressed water treatment of rice straw was conducted at 140-200℃ with or without phosphoric acid. When 0.7% phosphoric acid solution was used to hot compressed water treatment, about 80% of xylan in rice straw was successfully hydrolyzed to xylose at 160℃ for 15 min. Furthermore, the cellulose residue after this treatment was easily converted to glucose by enzymatic saccharification. The glucose yield was about 90%.
