Exiguobacterium mexicanum A-EM was isolated from seafloor hydrothermal vents(Caifan field, 14.0S 14.4 W) and was shown to degrade toxins and contaminants. Here, we present the complete genome sequence of A-EM, consisting of 2,412,492 bp, with a GC content of 53.16%. A-EM sequence contains genes encoding enzymes that degrade toxins and contaminants. Complete genome sequence of the strain A-EM can further provide insights into microbial adaption to the seafloor hydrothermal system and the genomic basis for the biotechnological application of strain A-EM as an efficient agent to degrade environmental contaminants.

Exiguobacterium mexicanum A-EM 从海底热液喷口（Caifan 油田，14.0S 14.4 W）中分离出来，并被证明可以降解毒素和污染物。在这里，我们展示了 A-EM 的完整基因组序列，由 2,412,492 bp 组成，GC 含量为 53.16%。A-EM 序列包含编​​码降解毒素和污染物的酶的基因。菌株 A-EM 的完整基因组序列可以进一步提供对微生物对海底热液系统的适应的见解，以及菌株 A-EM 作为降解环境污染物的有效试剂的生物技术应用的基因组基础。
