Abstract

A betaproteobacterium strain GR16-43 was isolated from a surface layer of the Geomnyong Pond in Republic of Korea by a dilution-to-extinction culturing method. We report the whole genome sequence of the strain GR16-43, which contains 4,806,848 bp with a G + C content 67.12%, and to include 4,424 protein-coding genes and 47 transfer RNA genes. The genome was determined to contain the genes encoding carbon monoxide dehydrogenase, nitrate reductase, nitrite reductase, nitric oxide reductase, and the sulfur oxidation (sox) gene cluster, highlighting the potential importance of the bacterial group represented by the strain in the cycling of inorganic elements. These results indicate that strain GR16-43 genome showed several traits indicating adaptation of the bacteria to living in freshwater environments.

그람 음성이며 긴 막대 모양의 betaproteobacteria에 속하는 GR16-43을 한강 발원지 검룡소에서 분리하였다. GR16-43 균주에 대한 유전체분석을 실시하였으며, G + C 비율이 67.12%인 4,806,848 bp 크기의 염기서열을 얻었다. 유전체 특징은 황산화와 관련된 다량의 유전자를 보유하고 있어 균주의 잠재적 중요성을 보여준다. 이러한 결과는 GR16-43 균주가 빈영양 담수 환경에서의 적응 연구를 위한 유전체 정보를 제공한다.
