Abstract
【解決手段】発酵原料を一時的に保管し、かつ、発酵原料を発酵槽に投入するための原料投入槽10と、発酵原料を減圧状態で発酵するための減圧発酵槽20と、減圧発酵槽20から回収した発酵生産物を一時的に保管するための発酵生産物回収槽30と、減圧発酵槽から回収した発酵終了後の発酵もろみを一時的に保管するための発酵もろみ回収槽40と、系内の空気を吸引し減圧状態に維持する減圧機50とを備え、発酵原料を原料投入槽10から減圧発酵槽20へ投入する工程、発酵生産物を発酵生産物回収槽30へ回収する工程、発酵終了後の発酵もろみを発酵もろみ回収槽40へ回収する工程を、減圧機50の吸引力を利用して行う。
【選択図】図1
Description
図1の減圧発酵システム1を利用して、エタノール発酵を行った例を説明する。原料投入槽10に、発酵原料12としての糖蜜(全糖濃度28%)200mlと、発酵性微生物としての酵母(サッカロマイセス・セルビシエ;Saccharomyces cerevisiae)と、酵素剤としてのコクゲンG20(α−アミラーゼ及びグルコアミラーゼ)を添加した。
減圧発酵システム1を利用してエタノールを生産した場合のエタノール生産量を測定した。なお、比較対照として、すべての工程を常圧で行った場合のエタノール生産量を測定した。
