Description

油脂含有排水は、内在する微生物等の働きにより油脂の一部が加水分解され、ｐＨ５．５からｐＨ６．０ぐらいの弱酸性となっている場合が多い。そこで本発明者は、弱酸性条件でも増殖・油脂分解可能なリパーゼ分泌微生物ならば、実際の油脂含有排水中の油を効果的に除去し、グリーストラップの浄化効果も高いと考えた。
そのために、本発明は、弱酸性の条件でも油脂を分解して増殖可能なリパーゼ分泌微生物により油脂を分解する油脂含有排水処理方法を特徴とする（請求項１）。さらに、請求項１に記載の油脂含有排水処理方法において、リパーゼ分泌微生物がバークホルデリア アルボリス（Burkholderia arbolis）であることを特徴とする（請求項２）。さらに、バークホルデリアアルボリス（Burkholderia arbolis）ＳＬ１Ｂ１株（受託番号NITE P-724）により油脂を分解する油脂含有排水処理方法を特徴とする（請求項３）。また、請求項１乃至３のいずれか一つに記載の油脂含有排水の処理方法により、グリーストラップに蓄積した油分をトラップ槽内で除去し、グリーストラップを浄化する方法を特徴とする（請求項４）。
また、弱酸性の条件でも油脂を分解して増殖可能なリパーゼ分泌微生物を含む油脂分解剤を特徴とする（請求項５）。さらに、請求項５に記載の油脂分解剤において、リパーゼ分泌微生物がバークホルデリア アルボリスであることを特徴とする（請求項６）。さらに、バークホルデリアアルボリス（Burkholderia arbolis）ＳＬ１Ｂ１株（受託番号NITE P-724）を含む油脂分解剤を特徴とする（請求項７）。
本発明による上記の方法と油脂除去剤を利用すれば、高濃度の油脂を含む厨房排水を処理する施設であるグリーストラップ内で油を分解処理して浄化することも可能である。
In many cases, fats and oils-containing wastewater is weakly acidic at a pH of about 5.5 to about 6.0 because a part of the oils and fats is hydrolyzed by the action of microorganisms and the like. Therefore, the present inventor considered that a lipase-secreting microorganism capable of growing and decomposing even under weakly acidic conditions effectively removes oil in the actual oil-containing wastewater and has a high purification effect of the grease trap.
To this end, the present invention is characterized by a method for treating fat and oil containing wastewater by decomposing oil and fat with a lipase-secreting microorganism capable of decomposing and growing oil and fat even under mildly acidic conditions (claim 1). Furthermore, in the method for treating fat and oil-containing wastewater according to claim 1, the lipase-secreting microorganism is Burkholderia arbolis (claim 2). Furthermore, the oil and fat-containing wastewater treatment method is characterized in that the oil and fat is decomposed by Burkholderia arbolis SL1B1 strain (Accession No. NITE P-724) (Claim 3). Further, the method for treating oil-containing wastewater according to any one of claims 1 to 3 is characterized in that the oil accumulated in the grease trap is removed in the trap tank to purify the grease trap. 4 ).
Further, the present invention is characterized by an oil and fat decomposing agent containing a lipase-secreting microorganism capable of decomposing and growing oil and fat even under weakly acidic conditions (Claim 5 ). Furthermore, in the oil and fat decomposing agent according to claim 5 , the lipase-secreting microorganism is Burkholderia alboris (claim 6 ). Furthermore, the oil-and-fat decomposer containing Burkholderia arbolis (Burkholderia arbolis) SL1B1 strain (Accession No. NITE P-724) is characterized (claim 7).
If the above-described method and fat removing agent according to the present invention are used, it is also possible to decompose and purify the oil in a grease trap, which is a facility for treating kitchen wastewater containing a high concentration of fat.
