sp. B6 is a Gram-positive, non-motile, facultative aerobic bacterium, isolated from the arsenic-contaminated aquifer sediment in the Datong basin, China. This strain displays high resistance to arsenic, and can dynamically transform arsenic under aerobic condition. Here, we described the high quality draft genome sequence, annotations and the features of sp. B6. The G + C content of the genome is 64.67%. This strain has a genome size of 4,663,437 bp; the genome is arranged in 8 scaffolds that contain 25 contigs. From the sequences, 3956 protein-coding genes, 264 pseudo genes and 89 tRNA/rRNA-encoding genes were identified. The genome analysis of this strain helps to better understand the mechanism by which the microbe efficiently tolerates arsenic in the arsenic-contaminated environment.
菌株B6是一种革兰氏阳性、无运动性、兼性需氧细菌，从中国大同盆地受砷污染的含水层沉积物中分离得到。该菌株对砷具有高度抗性，并且在有氧条件下能够动态转化砷。在此，我们描述了菌株B6的高质量草图基因组序列、注释及特征。该基因组的G + C含量为64.67%。此菌株的基因组大小为4,663,437 bp；基因组排列在8个支架中，包含25个重叠群。从这些序列中，鉴定出3956个蛋白质编码基因、264个假基因和89个编码tRNA/rRNA的基因。对该菌株的基因组分析有助于更好地理解微生物在砷污染环境中有效耐受砷的机制。
