[Synopsis] Antifungal compound, 2,4,6-trichrolophenol (TCP) has been frequently used as a component of the wood antiseptics, hence is widely distributed to environment. It was shown that the some part of TCP was methylated at hydroxyl residue and was converted into 2,4,6-trichroloanisole (TCA) by the various microbes. Since TCA has very strong musty odor at low concentration (ppb-ppt level) in aqueous solution, its diffusion into foods and other goods through plastic packing materials results in the deterioration of these goods with musty contamination. To prevent the formation of TCA, TCP should be removed from the environment. In the proceeding paper, it was shown that the elimination of TCP is achieved by the use of peroxidases (EC 1.11.1.7) derived from Arthromyces ramosus and horse raddish. [要約] 殺菌剤等の形で自然界に散布されて残留したり, フェノール含有排水の塩素処理によって生成したりして自然環境に存在する塩素化フェノールのTCPは微生物変換されて徽臭の強力なTCAになり, 食品等を汚染する。この徽臭汚染を防除する方法として, 2種類のPOD酵素を用いるTCP除去法を検討した。Arthromyces ramosusと西洋ワサビ由来PODはいずれも2units/ml程度で80ppm程度のTCP水溶液からTCPを除去しうることを示した。このPODによるTCP除去作用は官能テストによっても確認された。
