A Gram-reaction-negative, S-shaped, motile, poly-beta-hydroxybutyrate-accumulating, facultatively anaerobic, beige-pigmented bacterium, designated strain KMU-80(T), was isolated from seawater collected from the Republic of Korea. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the novel isolate was affiliated with the family Methylocystaceae, of the class Alphaproteobacteria, and that it possessed the greatest sequence similarity (96.7 %) to Terasakiella pusilla NBRC 13613(T). The DNA G+C content of KMU-80(T) was 48.3 mol%, and ubiquinone 10 was the sole respiratory quinone. The predominant cellular fatty acids consisted of C-18 : 1 omega 7c (60.2 %), C-16 : 0 (13.4 %) and C-16 : 1 omega 7c and/or C-16 : 1 omega 6c (11.1 %). Strain KMU-80(T) had phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unidentified aminolipid, an unidentified phospholipid and four unidentified lipids as polar lipids. Based on its distinct phylogenetic position and the combination of genotypic and phenotypic characteristics, this strain is considered to represent a novel species of the genusTerasakiella, for which the name Terasakiella salincola sp. nov. is proposed. The type strain ofT. salincola sp. nov. is KMU-80(T) (= KCCM 90274(T) = NBRC 112846(T)). An amended description of the genus Terasakiella is also provided.
