Abstract
In this study, we identified specific cultures of anaerobic bacteria that dechlorinate perchlorethene (PCE). The bacteria that significantly dechlorinated PCE were strain DCB-1, an obligate anaerobe previously shown to dechlorinate chlorobenzoate, and two strains of Methanosarcina. The rate of PCE dechlorination by DCB-1 compared favorably with reported rates of trichloroethene bio-oxidation by methanotrophs. Even higher PCE dechlorination rates were achieved when DCB-1 was grown in a methanogenic consortium.
摘要
在本研究中，我们鉴定出了能使全氯乙烯（PCE）脱氯的特定厌氧菌培养物。能显著使PCE脱氯的细菌是菌株DCB-1（一种先前已证明能使氯苯甲酸盐脱氯的专性厌氧菌）和两种甲烷八叠球菌菌株。DCB-1使PCE脱氯的速率与所报道的甲烷营养菌对三氯乙烯进行生物氧化的速率相比具有优势。当DCB-1在产甲烷菌联合体中生长时，甚至能实现更高的PCE脱氯速率。
