  • 초록

    Two Gram-negative, nonmotile, coccobacilli, SW- $3^T$ and SW- $100^T$ , were isolated from sea water of the Yellow Sea in Korea. Strains SW- $3^T$ and SW- $100^T$ contained ubiquinone-9 (Q-9) as the predominant respiratory lipoquinone and $C_{18:1}\;{\omega}9c$ and $C_{16:0}$ as the major fatty acids. The DNA G+C contents of strains SW- $3^T$ and SW- $100^T$ were 44.1 mol% and 41.9 mol%, respectively. A neighbor-joining tree based on l6S rRNA gene sequences showed that the two isolates fell within the evolutionary radiation enclosed by the genus Acinetobacter. Strains SW- $3^T$ and SW- $100^T$ exhibited a l6S rRNA gene similarity value of 95.7% and a mean DNA-DNA relatedness level of 9.2%. Strain SW- $3^T$ exhibited l6S rRNA gene sequence similarity levels of 93.5-96.9% to the validly described Acinetobacter species and fifteen Acinetobacter genomic species. Strain SW- $100^T$ exhibited l6S rRNA gene sequence similarity levels of less than 97.0% to the other Acinetobacter species except Acinetobacter towneri DSM $14962^T$ (98.0% similarity). Strains SW- $3^T$ and SW- $100^T$ exhibited mean levels of DNA-DNA relatedness of 7.3-l6.7% to the type strains of some phylogenetically related Acinetobacter species. On the basis of phenotypic, phylogenetic, and genetic data, strains SW- $3^T$ and SW- $100^T$ were classified in the genus Acinetobacter as two distinct novel species, for which the names Acinetobacter marinus sp. novo (type strain SW- $3^T$ =KCTC KCTC $12259^T$ =DSM <TEX DSM $16312^T$ ) and Acinetobacter seohaensis sp. novo (type strain SW- $100^T$ =KCTC < KCTC $12260^T$ =DSM <TEX DSM $16313^T$ ) are proposed, respectively.
