Abstract
Clostridium bifermentans strain DPH-1 reportedly dechlorinates tetrachloroethene (PCE) to cis-1,2-dichloroethene. Cultivation-based approaches resolved the DPH-1 culture into two populations: a nondechlorinating Clostridium sp. and PCE-dechlorinating Desulfitobacterium hafniense strain JH1. Strain JH1 carries pceA, encoding a PCE reductive dehalogenase, and shares other characteristics with Desulfitobacterium hafniense strain Y51.
摘要
据报道，双发酵梭菌菌株DPH-1可将四氯乙烯（PCE）脱氯生成顺式1,2-二氯乙烯。基于培养的方法将DPH-1培养物解析为两个菌群：一个是非脱氯的梭菌属菌株，另一个是能使PCE脱氯的哈氏脱硫肠状菌菌株JH1。菌株JH1携带编码PCE还原脱卤酶的pceA，并且与哈氏脱硫肠状菌菌株Y51具有其他共同特征。
