Abstract
|
|
|
Cupriavidus sp. strain SW-Y-13 is an aerobic, Gram-negative, rod-shaped bacterium isolated from river water in South Korea, in 2019. Its draft genome was produced using the PacBio RS II platform and is thought to consist of five circular chromosomes with a total of 7,307,793 bp. The genome has a G + C content of 63.1%. Based on 16S rRNA sequence similarity, strain SW-Y-13 is most closely related to Cupriavidus metallidurans (98.4%). Genome annotation revealed that the genome is comprised of 6,613 genes, 6,536 CDSs, 12 rRNAs, 61 tRNAs, and 4 ncRNAs. Resistance to Co2+ is primarily mediated by the efflux system encoded by the SW-Y-13 genome, which includes the czcCBA operons, czcD genes, and czcN genes, among others.
This study may provide useful information on the heavy-metal resistance mechanisms of strain SW-Y-13.
