Description
本出願は、2014年7月11日出願の米国特許出願第14/329,881号の利益を主張し、その内容は、参照により本明細書に組み込まれる。
従来の「時間ベースの」始動と本発明の「自動」始動との比較
C.ljundahliiを含む培養液を接種することによって、COからエタノールへの変換の生物学的プロセスを開始した。培養液のpHは、酢酸が生成されるに従い、低下し始めた。培養液のpHが5.0に達したとき、バイオリアクタへのCO含有基質及び水酸化アンモニウム供給を開始した。始動の間中のCO含有基質流量を、CO供給過剰の回避が主な目標であった従来の規定の時間ベースのプロファイルによって管理した。比較目的のため、水酸化アンモニウムの流量が培養液中の(酢酸の形態の)酢酸塩の濃度に基づいて制御され、HPLCによって自動的かつ定期的に測定された、本明細書に記載される制御方法を使用して同じプロセスを開始した。これらの比較始動の進捗を、2日の期間にわたる培養液中のエタノール、細菌、及び酢酸の濃度を提供する図2及び図3に示す。この情報は、本発明の代表的な実施形態に従った、従来の時間ベースの始動の場合(図2−「時間ベースの制御」)、及び自動始動の場合(図3−「自動制御」)で提供される。
自動始動−測定された濃度に基づいたNH4OH流の制御
C.ljundahlnを含む培養液を接種することによって、COからエタノールへの変換の生物学的プロセスを開始した。培養液のpHは、酢酸が生成されるに従い、低下し始めた。培養液のpHが5.0に達したとき、バイオリアクタへのCO含有基質及び水酸化アンモニウム供給を開始した。バイオリアクタ内の測定された細菌濃度に基づいて、酢酸塩(酢酸)目標濃度及び希釈剤流量を以下の等式に従って決定し、
自動始動−測定されたpH及びCO含有基質流量のみに基づく
生物学的プロセスの先の始動データに基づいて、C.ljundahliiを含む培養液にCOを供給することによりCOをエタノールに変換した実施例1に記載されるように、反応器内の所与の細菌濃度と、目標酢酸生産性を得るためにそれを必要とした所与の組成物のCO含有基質の対応する流量と、培養液のpHを所与の目標に維持するために必要な、必要とされる水酸化アンモニウム流量との間の関係を確立した。これらの関係は、以下のとおりであった:
Claims (9)
