从大西洋表层海水中分离到一株革兰氏染色阴性、需氧、橙色、无鞭毛、游动、杆状细菌,命名为SM 1354(T)。该菌株水解明胶和DNA,但不还原硝酸盐。它在4-40 °C和0.5-11%(w/v)NaCl下生长。16 S rRNA基因序列分析表明,菌株SM 1354(T)属于Marivirga属,与Marivirga属已知种的同源性为96.0-96.2%。菌株SM 1354(T)的主要脂肪酸为异C15:0、异C15:1G、异C17:03-OH和总和特征3(C16:1ω 7 c和/或异C15:02-OH)。菌株SM 1354(T)的极性脂质包括磷脂酰乙醇胺、3种未鉴定的脂质和1种未鉴定的氨基脂质和氨基磷脂。菌株SM 1354(T)的主要呼吸醌是甲萘醌7(MK-7)。菌株SM 1354(T)基因组DNA G+C含量为33.9 ± 0.4mol%。根据本研究的多相特征,提出菌株SM 1354(T)代表Marivirga属的一个新种,即Marivirga atlantica sp. nov.,模式菌株为SM 1354(T)(=CCTCC AB 2014242(T)=JCM 30305(T))。  本文还对该属的描述作了修正。
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.
