Chlorobenzenes are ubiquitously distributed, highly persistent, and toxic environmental contaminants. Pandoraea pnomenusa MCB032 was isolated as a new dominant chlorobenzene-utilizing strain from a functionally stable bioreactor during the treatment of chlorobenzenes when strain Burkholderia sp. JS150 disappeared. In study, we report the complete genome sequence of strain MCB032 which consists of a circular chromosome and three plasmids, which are ~ 6 Mb in length with 5450 open reading frames-12 encoding rRNAs and 77 encoding tRNAs. We further identified 17 putative genes encoding the enzymes involved in the methyl-accepting chemotaxis proteins in sensing chemical gradients during chemotaxis. The annotated complete genome sequence of this strain will provide genetic insights into the degradation of chlorinated aromatic compounds. The information will empower the elucidation of chlorobenzene affinity hierarchy and species succession in the bioreactor.
氯苯是一种普遍存在、高度持久且有毒的环境污染物。在处理氯苯时,功能性稳定的生物反应器中,苯并杆菌属 JS150 消失后,泛菌属 MCB032 被分离为一种新的优势氯苯利用菌株。在本研究中,我们报告了菌株 MCB032 的完整基因组序列,该序列由一个环状染色体和三个质粒组成,长度约为 6Mb,包含 5450 个开放阅读框——其中 12 个编码 rRNA,77 个编码 tRNA。我们进一步鉴定了 17 个可能编码参与趋化过程中感知化学梯度的甲基受体趋化蛋白的酶的基因。该菌株的注释完整基因组序列将为研究氯化芳香族化合物的降解提供遗传见解。这些信息将有助于阐明生物反应器中氯苯亲和力层次和物种演替。
