Pa-245 固体培養によるオンサイト生産酵素を用いたタケパルプからのエタノール生産(ポスターセッション1:2.技術,研究発表,(ポスター発表)) Pa-245 Ethanol production from take pulp under simultaneous saccharification and fermentation using onsite produced enzyme by solid-state fermentation
Bamboo plants grow rapidly, reaching their maximum size within a few months. Effective ways of utilizing bamboo are also attractive from a landscape preservation perspective. Bamboo pulp was prepared by soda-anthraquinone cooking to increase the susceptibility to cellulase. The combined whole crushed medium from Trichoderma reesei and Aspergillus tubingensis, grown on the solid-state medium was mixed with thermotolerant yeast Saccharomyces cerevisiae BA-11 to gain higher ethanol concentration under simultaneous saccharification and fermentation. The addition of Aspergillus enzyme resulted in an increased ethanol concentration of 4.4 wt% and the ethanol yield of 80% at 40℃ after 6 days of fermentation in a small reactor having a working volume of about 0.7 L.
