Abstract

A Gram-negative-staining, non-motile, non-spore-forming and strictly aerobic bacterial strain, SC35, was isolated from tidal flat sediment collected from the South Sea, Korea, and subjected to a taxonomic study using a polyphasic approach. The organism grew optimally at 20–30 °C and with 1–2 % (w/v) NaCl. Strain SC35 contained ubiquinone-8 as the predominant respiratory lipoquinone and C 9 as the major fatty acid. The DNA GC content was 48.5 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain SC35 formed a lineage within the genus (94.3–96.5 % sequence similarity), forming a distinct branch in a clade also containing NIBH P2K6 and SW-238. On the basis of phenotypic and phylogenetic data, strain SC35 (=KCTC 22503=JCM 16343) was placed in the genus as the type strain of a novel species, for which the name sp. nov. is proposed.
