title: Marivirga atlantica sp. nov., isolated from seawater and emended description of the genus Marivirga.
abstract: A novel Gram-stain-negative, aerobic, orange-pigmented, non-flagellated, gliding, rod-shaped bacterium, designated strain SM1354(T) 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(T) belonged to the genus Marivirga with 96.0-96.2% sequence similarities to known species of the genus Marivirga . The major fatty acids of strain SM1354(T) were iso-C15 : 0, iso-C15 : 1 G, iso-C17 : 03-OH and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 02-OH). Polar lipids of strain SM1354(T) included phosphatidylethanolamine, three unidentified lipids and one unidentified aminolipid and aminophospholipid. The major respiratory quinone of strain SM1354(T) was menaquinone 7 (MK-7). The genomic DNA G+C content of strain SM1354(T) 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(T) represents a novel species of the genus Marivirga , namely Marivirga atlantica sp. nov. The type strain of Marivirga atlantica is SM1354(T) ( =CCTCC AB 2014242(T) =JCM 30305(T)). An emended description of the genus Marivirga is also proposed.
