Abstract
Description
前記微生物は、トリコスポロンルビエリ(Trichosporon loubieri Y1-A)(寄託番号:KCTC 18079P)、トリコスポロンクタネウム(Trichosporon cutaneum)または木材表面に寄生する白色腐朽菌からなる群から選択される少なくとも1種である。
前記親油性物質粉末は、天然ワックス、合成ワックス、蝋、ろうそくからなる群から選択される少なくとも1種である。
前記微生物栄養物質は、糖類及び大豆粉を含む。
前記微生物製剤は、前記微生物及び培養ろ液重量%に対して、親油性粉末1〜10重量%、糖類0.1〜1重量%及び大豆粉0.01〜0.1重量%を含む。
また、汚染物質が粉末表面に吸着された状態で、微生物により分解されるために、毒性汚染物質の微生物体内への流入や菌体に吸着される量が減少し、分解微生物に対する毒性が低下するので、生分解作用が安定的に維持される。
本発明の微生物製剤は、油類及び毒性化学物質の分解能を有する微生物及び培養ろ液、親油性物質粉末ならびに微生物栄養物質を含む混合物を含有する。
前記微生物は、トリコスポロンルビエリ(Trichosporon loubieri Y1-A)(寄託番号:KCTC 18079P)、トリコスポロンクタネウム(Trichosporon cutaneum)及び木材表面に寄生する白色腐朽菌からなる群から選択される少なくとも1種である。
前記微生物の有用な例は、油類及び毒性化学物質の分解能を有する公知の微生物、好ましくは、トリコスポロン属、トリコスポロンクタネウム及び木材表面に寄生する白色腐朽菌からなる群から選択される少なくとも1種、あるいはそれらの混合微生物を含む。
より好ましくは、トリコスポロン属菌株は、本発明者が新規に開発したトリコスポロンルビエリ(寄託番号:KCTC 18079P)であることがさらに望ましい。木材表面に寄生する白色腐朽菌のより好ましい例は、ファネロカエテ属(Phanerochaete spp.)、フレウロタス属(Phleurotus spp.)などである。
前記ワックス、蝋、ろうそくなどのような親油性物質粉末の粒径が小さくなるほど、親油性粉末の体積当りの表面積が増加して、前記油類または毒性化学物質を容易に粉末に吸着させ、微生物との接触面積を大きく広げることによって、微生物の油類及び毒性化学物質の分解効率を最大化させる。
微生物の生存率を高めるために、前記微生物栄養物質は糖類を含み、嫌気性状態下で、酸素の代わりに電子受容体として作用する天然栄養物質である大豆粉を含むことが好ましい。
以下、実施形態を通じて本発明をさらに詳細に説明する。但し、下記実施例は、本発明の例示であるだけで、本発明の範囲がそれらのみに限定されるものではない。
1.汚染土壌の製造
実験室内でディーゼル油とナフサとを混合して、10,000ppm濃度のTPH(Total Petroleum Hydrocarbon)溶液2,400mlを調製した。次いで、105℃で2時間ずつ2回、間歇殺菌した土壌6,000mlに添加して均一に混ぜて混合した後、室温にて密閉容器内で24時間静置し、汚染土壌を最終的に製造した。
このように製造した土壌400mlずつを500ml容量の三角フラスコに分けて入れ、適正の土壌水分に調整するために、各フラスコに蒸溜水50mlずつを添加した後に密封した。
前記のように準備された15個の土壌試料に、下記のような方法で5種の処理群を作ってそれぞれ3回ずつ反復して実験を行った。15個の試料を含む容器を密封して、15℃で2週間保管した。その後、各処理群別に土壌試料を採取し、土壌汚染工程試験方法によって油類を抽出した。気体クロマトグラフィ(GC−HP6890、Hewlette Packerd Co.,U.S.A)を使用してTPH濃度を測定した。密封された試料は、一日に一回ずつ約1分間密封されたふたを開けて、現場と同じ間歇的な空気循環をさせた。
このような方法で実験した結果を、下の表1に表した。
処理群別の処理方法は、
(1)ワックス粉末0.01g+グルコース0.001g+100ppmのH2O2を0.5ml+トリコスポロン属微生物培養液1ml、
(2)ワックス粉末0.01g+グルコース0.001g+100ppmのH2O2を0.5ml、
(3)グルコース0.001g+100ppmのH2O2を0.5ml+トリコスポロン属微生物培養液1ml、
(4)グルコース0.001g+100ppmのH2O2を0.5ml、
(5)100ppmのH2O2を0.5ml
である。
原油で汚染された土壌を、実際の汚染現場で、深さ別に6ケ所で採取して密封後、低温状態で研究所に運搬して均一によく混ぜた後、下記のように処理した。
(1)汚染土220g+滅菌したトリコスポロン属微生物製剤1.5ml
(2)汚染土220g+トリコスポロン属微生物製剤1.5ml
(3)汚染土220g+親油性天然ワックス粉末0.015gと混合培養したトリコス
ポロン属微生物製剤1.5ml
使われた選択培地は、土壌内の土着細菌が成長できないように、2種類の抗生物質を添加したPDA培地をから調製した。図2に示すように、トリコスポロン属菌株のみ育つことが確認された。
(1)親油性成分による微生物製剤の汚染油類分解効果の増大及び全体復元期間の短縮による汚染土壌及び地下水浄化コストが低減される。
(2)天然成分の栄養物質の使用による微生物製剤の製造コストが低減される。
(3)無機イオン及びいろいろな種類のビタミンを含有した天然成分材料の使用による投入微生物の増殖率と活性増大及びそれによる生態系適応性及び生存力が高くなる。
(4)微生物製剤に含まれた選択微生物による毒性化学物質の分解と、それによる土着微生物の活性及び個体数が増加して全体処理効率が高くなり、土壌生態系の破壊なしに復元が可能である。
(5)従来の土壌及び地下水処理方法と併用する時に処理効果の上昇を期待でき、既存処理方式の問題点を克服できて、環境産業上非常に有用な発明である。
