A Gram-negative, motile, strictly aerobic, violet-pigment-producing bacterium, designated strain FR1199T, was isolated from tidal flat sediment of Byunsan, South Korea. Phylogenetic analysis of the 16S rRNA gene sequence revealed that strain FR1199T represents a distinct line of descent within the genus Pseudoalteromonas. The phenotypic features of strain FR1199T were similar to those of Pseudoalteromonas phenolica and Pseudoalteromonas luteoviolacea, but several physiological and chemotaxonomical properties readily distinguished strain FR1199T from these species. Major fatty acids were straight-chain saturated (C(16 : 0)) and monounsaturated C(18 : 1)omega7c fatty acids. The DNA G+C content was 39 mol%. On the basis of polyphasic evidence, it is concluded that the isolate represents a novel species within the genus Pseudoalteromonas, for which the name Pseudoalteromonas byunsanensis sp. nov. is proposed. The type strain is FR1199T (=JCM 12483T=KCTC 12274T).
从韩国边山的潮滩沉积物中分离出一株革兰氏阴性、具运动性、严格需氧、产紫色色素的细菌，命名为FR1199T菌株。16S rRNA基因序列的系统发育分析表明，FR1199T菌株代表了假交替单胞菌属内一个独特的进化分支。FR1199T菌株的表型特征与酚假交替单胞菌和紫假交替单胞菌相似，但一些生理和化学分类学特性很容易将FR1199T菌株与这些种区分开来。主要脂肪酸为直链饱和脂肪酸（C(16 : 0)）和单不饱和脂肪酸C(18 : 1)ω7c。DNA G+C含量为39 mol%。基于多相证据，得出该分离株代表假交替单胞菌属内一个新种的结论，为此提出边山假交替单胞菌新种（Pseudoalteromonas byunsanensis sp. nov.）。模式菌株为FR1199T（=JCM 12483T=KCTC 12274T）。
