A new strain, K08M4, was isolated from the broad-nosed pipefish in the Kiel Fjord. Infection experiments revealed that K08M4 was highly virulent for juvenile pipefish. Cells of strain K08M4 were Gram-stain-negative, curved rod-shaped and motile by means of a single polar flagellum. The strain grew aerobically at 9-40° C, at pH 4-10.5 and it tolerated up to 12 % (w/v) NaCl. The most prevalent (>10 %) cellular fatty acids of K08M4 were C 7 and C. Whole-genome comparisons revealed that K08M4 represents a separate evolutionary lineage that is distinct from other species and falls within the clade. The genome is 4,886,292 bp in size, consists of two circular chromosomes (3,298,328 and 1, 587,964 bp) and comprises 4,178 protein-coding genes and 175 RNA genes. In this study, we describe the phenotypic features of the new isolate and present the annotation and analysis of its complete genome sequence. Based on these data, the new isolate represents a new species for which we propose the name sp. nov. The type strain is K08M4 (=DSM 109818=CECT 30086).
一种新的菌株,K08M4,是从基尔峡湾的宽鼻笛鲷中分离出来的。感染实验表明,K08M4 对幼年笛鲷具有高度的致病性。K08M4 菌株的细胞革兰氏染色阴性,呈弯曲的杆状,通过单一极鞭毛运动。该菌株在 9-40°C、pH4-10.5 的条件下需氧生长,可耐受高达 12%(w/v)的 NaCl。K08M4 最常见的(>10%)细胞脂肪酸是 C7 和 C。全基因组比较表明,K08M4 代表一个与其他物种不同的单独进化谱系,属于 分支。基因组大小为 4886292bp,由两个圆形染色体(3298328bp 和 1587964bp)组成,包含 4178 个蛋白质编码基因和 175 个 RNA 基因。在本研究中,我们描述了新分离株的表型特征,并对其全基因组序列进行了注释和分析。基于这些数据,新分离株代表了一个新的物种,我们建议将其命名为 sp. nov. 。模式菌株为 K08M4(=DSM 109818=CECT 30086)。
