Trichloroethylene was metabolically activated by toluene dioxygenase to produce toxic effects in Pseudomonas putida F1. Cytotoxicity was indicated by growth inhibition and by the covalent modification of cellular molecules in P. putida F1 exposed to [C]trichloroethylene. With a toluene dioxygenase mutant, neither growth inhibition nor alkylation of intracellular molecules was observed.
三氯乙烯被甲苯双加氧酶代谢激活,从而对恶臭假单胞菌 F1 产生毒性作用。恶臭假单胞菌 F1 暴露于 [C]三氯乙烯时,细胞生长受到抑制以及细胞内分子的共价修饰表明其具有细胞毒性。使用甲苯双加氧酶突变体时,未观察到细胞生长抑制或细胞内分子的烷化。
