Description
「DO」は、溶存酸素を表す。
プロセス流中の微生物活動は、細胞が好気呼吸状態下で生成しているATPの量と溶存酸素の消費量が直接的に関連するため、溶存酸素の消費をモニタリングすることによって間接的に測定でき、細胞が生成するATPの量は前記プロセス流中の微生物活動のレベルと相関付けできる。本発明に記載の方法は、好気呼吸が微生物細胞中のエネルギ生成の主経路ではない場合の低レベルのDOを有するプロセス流に対しては好適ではない。
機構はプロセス流中の溶存酸素を実際に測定するために開発された。例えばORPプローブのような、他の分析装置はこの機構に付随してもよい。
プロセス流中のバルク型の(全体の)微生物学的活性をモニタリングする方法が開示される。バルク型の(全体の)微生物学的活性は、プロセス流中のプランクトン様の微生物及び固着性の微生物のような、バルク型のプロセス流中の微生物活動である。
表面結合型の微生物学的活性は、例えば生物膜のような、表面型微生物の微生物活動である。
バルク型の微生物学的活性は、表面結合型の微生物学的活性と併用してモニタリングできる。プロセス流中のバルク型の微生物学的活性と、表面結合型の微生物学的活性とを測定する方法は、(a)機構を前記プロセス流に連結するステップであって、前記機構が、複数の開口を含むフローセルであって、少なくとも1の開口が前記プロセス流から引き込まれる流体用のフローセル入口であり、少なくとも1の開口が前記フローセルを出る流体用のフローセル出口であるフローセルと、前記開口のうちの1つに取付けられる1つのDOプローブと、選択的に前記開口のうちの1つに取付けられるORPプローブと、前記開口のうちの1つに取付けられる洗浄装置と、選択的にフローセル入口に取り付けられる第1の導管と、選択的にフローセル出口に取り付けられる第2の導管と、前記フローセルに付随するバルブとを含むステップと、(b)流体が前記フローセル内に引き込まれるのを可能にすべく、前記機構のバルブを開けるステップと、(c)前記プロセス流から前記フローセル内に前記流体を引き込むステップと、(d)前記DOプローブで前記プロセス流のDO濃度を少なくとも1回測定するステップであって、前記DOプローブは各測定前に洗浄されないステップと、(e)前記DOプローブの表面を洗浄するステップと、(f)前記DOプローブで前記機構内部の流体のDO濃度を少なくとも1回測定するステップであって、選択的に各測定前に前記DOプローブの表面が洗浄されるステップと、(g)更なる流体が前記フローセル内に引き込まれるのを防ぐために前記機構のバルブを閉じるステップと、(h)前記DOプローブで前記機構内部の流体のDO濃度を少なくとも1回測定するステップであって、各測定前に前記DOプローブの表面が洗浄されるステップと、(i)ステップ(f)とステップ(h)との間のΔDOの読取り値を計算し、前記ΔDOを前記プロセス流中の前記バルク型の微生物学的活性と少なくとも相関づけるステップと、(j)ステップ(d)とステップ(f)との間のΔDOの読取り値を計算し、前記ΔDOを前記プロセス流中の前記表面結合型の微生物学的活性と少なくとも相関づけるステップとを含む。
