Description
(グルコース濃度及びキシロース濃度は培養開始前の初期濃度である)
次に、26質量%の希硫酸処理コーンストーバ由来酵素糖化液を培地とし、該培地にMeyerozyma guilliermondi N株の培養液を培地のOD600が0.5となるように添加し、30℃の温度で100時間培養を行った。前記希硫酸処理コーンストーバ由来酵素糖化液は、グルコース64g/L、キシロース48g/Lを含みpH6であった。そして、前記培養後に前記培地を採取してエタノールの濃度をGC−FID(ジーエルサイエンス株式会社製、商品名:GC390B)により測定し、式(1)により発酵収率を算出した。結果を図3に示す。
