Abstract

A marine bacterium, designated IMCC2115, was isolated from coastal seawater (Yellow Sea, Korea) using a high throughput cultivation method based on dilution-to-extinction, and taxonomically investigated. Cells of the strain formed tiny, beige to off-white colonies and were Gram-stain-negative, obligately aerobic, chemoheterotrophic, non-motile cocci. Based on 16S rRNA gene sequence comparisons, the strain was most closely related to the genera (92.0–92.4 %) and (91.6–92.8 %), but phylogenetic trees showed that the strain formed a distinct phyletic line in the class adjacent to the OM60 and SAR92 clades. The DNA G+C content of the strain was 47.8 mol% and the predominant cellular fatty acids were anteiso-C (67.6 %), anteiso-C (14.4 %) and C (6.9 %). The 16S rRNA gene sequence analyses and phenotypic and chemotaxonomic tests allowed the differentiation of IMCC2115 from other related genera in the class . Therefore, strain IMCC2115 (=KCCM 42369 =NBRC 102686) is proposed as the representative of a new genus and species, for which the name gen. nov., sp. nov. is proposed.
