The culturomics method enabled isolation of a new member of the Ottowia genus from the stool sample of a healthy volunteer. Strain Marseille-P4747T exhibited a 96.18% 16S rRNA sequence identity with Ottowia beijingensis strain GCS-AN-3 (NR_133803.1), the closest species with standing in nomenclature. It is a Gram-stain-negative, nonmotile, and aerobic bacterium. It does not possess catalase and oxidase activities. Its genome has a size of 2 830 447 bp and a G + C content of 63.5 mol%. Based on the phylogenic, phenotypic, and genomic analyses, we conclude that Ottowia massiliensis sp. nov. is a new species, represented by Marseille-P4747T ( = CSUR P4747 = CECT 30348) as type strain.
文化组学方法使我们能够从一名健康志愿者的粪便样本中分离出一个新的 Ottowia 属成员。菌株 Marseille-P4747T 与最接近的命名种北京鞘氨醇单胞菌（NR_133803.1）的 16S rRNA 序列相似度为 96.18%。它是革兰氏阴性、非运动和需氧细菌。它不具有过氧化氢酶和氧化酶活性。其基因组大小为 2 830 447 bp，G+C 含量为 63.5 mol%。基于系统发育、表型和基因组分析，我们得出结论，Ottowia massiliensis sp. nov. 是一个新的物种，马赛 P4747T 株（=CSUR P4747=CECT 30348）为其模式菌株。
