Abstract

Toluene dioxygenase from Pseudomonas putida F1 has been implicated as an enzyme capable of degrading trichloroethylene. This has now been confirmed with Escherichia coli JM109(pDTG601) that contains the structural genes (todC1C2BA) of toluene dioxygenase under the control of the tac promoter. The extent of trichloroethylene degradation by the recombinant organism depended on the cell concentration and the concentration of trichloroethylene. A linear rate of trichloroethylene degradation was observed with the E. coli recombinant strain. In contrast, P. putida F39/D, a mutant strain of P. putida F1 that does not contain cis-toluene dihydrodiol dehydrogenase, showed a much faster initial rate of trichloroethylene degradation which decreased over time.

摘要

恶臭假单胞菌F1中的甲苯双加氧酶被认为是一种能够降解三氯乙烯的酶。现在,含有在tac启动子控制下甲苯双加氧酶结构基因(todC1C2BA)的大肠杆菌JM109(pDTG601)已证实了这一点。重组生物对三氯乙烯的降解程度取决于细胞浓度和三氯乙烯浓度。大肠杆菌重组菌株对三氯乙烯的降解呈线性速率。相比之下,恶臭假单胞菌F1的突变株恶臭假单胞菌F39/D不含有顺式甲苯二氢二醇脱氢酶,其对三氯乙烯的初始降解速率要快得多,但会随时间下降。
