通过哺乳动物的代谢(F.Korte和H.Arent,Life Sci. 4:2017,1965)和昆虫(D.F.HeathandM. Vanderkar,Brit.J.Ind.Med.21:269,1964),但对微生物降解这一重要农药知之甚少。科特塔尔。(Ann.Chem.Liebigs 656:135,1962)和Chacko埃塔尔。(科学154:893,1966)报道了不含戊二醇的微生物不能降解狄氏剂;然而,最近Matsumura和Boush(Science 156:959,1967)从许多具有类似活性的土壤样品中分离出几种能降解狄氏剂的假单胞菌和芽孢杆菌。他们并没有特别尝试鉴定形成的狄氏剂代谢物,但他们确实建议,基于与真实对照相同的RF值,6,7-反式-二羟基二氢艾氏剂(艾氏剂二醇)可能是主要产物。在这个实验室同时进行的工作表明,另一种普遍存在的细菌,产气荚膜杆菌,在体外将狄氏剂转化为色谱上类似于6,7-反式二氢的化合物。

Korteetal.(Ann.Chem.Liebigs 656:135, 1962) andChacko etal.(Science 154: 893, 1966) reported that anumberofubiquitous microorganisms wereincapable ofdegrading dieldrin; however, morerecently Matsumura and Boush(Science 156:959, 1967)isolated several species ofPseudomonas andBacillus which could degrade dieldrin, fromanumberofsoil samples having similar activity. Theydidnotspecifically attempt toidentify thedieldrin metabolites formed, buttheydidsuggest, onthebasis ofan identical RFvalue with anauthentic control that 6,7-trans-dihydroxydihydroaldrin (aldrin diol) mightbea majorproduct.
