Abstract

A novel Gram-stain-negative, aerobic, orange-pigmented, non-flagellated, gliding, rod-shaped bacterium, designated strain SM1354 was isolated from surface seawater of the Atlantic Ocean. The strain hydrolysed gelatin and DNA but did not reduce nitrate. It grew at 4–40 °C and with 0.5–11 % (w/v) NaCl. Phylogenetic analysis of the 16S rRNA gene sequences revealed that strain SM1354 belonged to the genus with 96.0–96.2 % sequence similarities to known species of the genus . The major fatty acids of strain SM1354 were iso-C, iso-C G, iso-C3-OH and summed feature 3 (Cω7 and/or iso-C2-OH). Polar lipids of strain SM1354 included phosphatidylethanolamine, three unidentified lipids and one unidentified aminolipid and aminophospholipid. The major respiratory quinone of strain SM1354 was menaquinone 7 (MK-7). The genomic DNA G+C content of strain SM1354 was 33.9±0.4 mol%. On the basis of the results of the polyphasic characterization in this study, it is proposed that strain SM1354 represents a novel species of the genus , namely sp. nov. The type strain of is SM1354 ( = CCTCC AB 2014242 = JCM 30305). An emended description of the genus is also proposed.
