Abstract
Dechlorination of DDT to DDD in higher animals requires the presence of molecular oxygen, but in microorganisms the presence of oxygen hinders dechlorination. In cell-free preparations of Aerobacter aerogenes, the use of selected metabolic inhibitors indicated that reduced Fe(II) cytochrome oxidase was responsible for DDT dechlorination. This finding may possibly explain. the persistence of DDT residues in soils and sediments.
摘要
在高等动物中，滴滴涕向滴滴伊的脱氯作用需要分子氧的存在，但在微生物中，氧的存在会阻碍脱氯作用。在产气杆菌的无细胞制剂中，使用选定的代谢抑制剂表明，还原的 Fe(II)细胞色素氧化酶是滴滴涕脱氯的原因。这一发现可能可以解释滴滴涕残留于土壤和沉积物中的持久性。
