Abstract

Strain LA220, isolated from seawater of the Eastern Pacific Ocean, was subjected to a polyphasic taxonomic study. Cells of the strain were Gram-stain-negative, aerobic, motile and short rod-shaped. On the basis of 16S rRNA gene sequence analysis, strain LA220 showed high similarity to SD10 (98.5 %), DSM 19595 (98.3 %) and P38 (97.5 %), and exhibited less than 97.0 % 16S rRNA gene sequence similarity with respect to the type strains of other species. Phylogenetic analyses revealed that strain LA220 fell within the cluster of the genus . The average nucleotide identity and DNA–DNA hybridization values between strain LA220 and the type strains of species were 74.8–76.8 and 18.4–20.8 %, respectively. The sole respiratory quinone was ubiquinone-10 (Q-10). The principal fatty acids were summed feature 8 (Cω7 and/or Cω6) and C. The major polar lipids were three unidentified glycolipids. The DNA G+C content was 59.9 mol%. Phylogenetic distinctiveness, chemotaxonomic differences and phenotypic properties revealed that strain LA220 could be differentiated from recognized species. Therefore, strain LA220 is considered to represent a novel species of the genus , for which the name sp. nov. (type strain LA220=CGMCC 1.15928=KCTC 52577) is proposed.
