Arthrobacter 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 Arthrobacter 
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.
