Abstract
The saccharification of the Sasa senanensis waste using hot compressed water treatment for enzymatic hydrolysis was investigated. Hot compressed water treatment of the Sasa senanensis waste was conducted at 180-260 °C and followed by enzymatic saccharification. After the enzymatic saccharification treatment, the highest total sugar yield (52 % on the feedstock base) was obtained from the Sasa senanensis waste pretreated at a temperature of 200 °C and holding time of 5 min. Glucose enzymatically produced was rapidly converted to ethanol within 8 h without any fermentation inhibitor. Approximately 100 % of theoretical yield of ethanol was obtained from glucose. The Sasa senanensis waste may be suitable for the feedstock of ethanol production from fermentable sugars because no inhibition was observed during the enzymatic saccharification and ethanol fermentation.
