Description
Meyerozyma guilliermondiiの親株を稲わら由来の糖液を用い培養を行った。熊谷産の稲わらを、等量の25%アンモニア水に80℃3時間漬け込んだ後、アンモニアを放散させた。処理したバイオマスは、pHを10%NaOHで4に調整後、アクレモニウムセルラーゼ(Meiji Seika ファルマ社製)を添加して、50℃で72時間酵素糖化を行った。作成したスラリーはフィルタープレス法にて固液分離を行い液体を回収した。この液体(以下、清澄液ともいう。)を用いて、変異剤を加えながら19ヶ月馴化培養を行い、発酵性能向上株を選抜した。選抜は一定時間後のエタノール量を基準に行った。発酵性能の高い菌株を独立行政法人製品評価技術基盤機構 特許微生物寄託センターに、寄託番号NITE BP−01964として寄託した。
2.1 エタノール産生能
図1は親株であるN株に対するBP−01964株のエタノール産生量を示す。コーンストーバーを希硫酸処理した糖化液をNaOH水溶液でpHを6に調整して用い、同株の培養液を培地のOD600が2.0となるように添加し、30℃、96時間培養した後の培養液中のエタノール量を示す。糖化溶液のグルコースは、63.2g/L、キシロースは34.5g/Lであった。エタノール測定はGC−FID(ジーエルサイエンス社製:GC390B)を用いた。
バイオエタノール産生を行うときに、スラリー、清澄液、どちらを用いた場合であっても効率よく発酵する菌であることが望ましい。そこで、スラリー、清澄液を用いて発酵収率を比較した。発酵収率は以下の式により計算される。
発酵収率=得られたエタノール量(g/L)/発酵開始時の糖液に含まれていたグルコース+キシロース量(g/L)/0.5114
稲わらと同様に、コーンストーバーもバイオエタノール産生に多用されるバイオマスである。本菌株は稲わらから製造した清澄液を用いて馴化を行い、単離した菌株であるが、コーンストーバーでも同様にバイオエタノールを効率よく産生する。
