Marseille-P9602 is a Chryseobacterium-like strain that we isolated from planarian Schmidtea mediterranea and characterized by taxono-genomic approach. We found that Marseille-P9602 strain exhibits a 16S rRNA gene sequence similarity of 98.76% with Chryseobacterium scophthalmum LMG 13028 strain, the closest phylogenetic neighbor. Marseille-P9602 strain was observed to be a yellowish-pigmented, Gram-negative, rod-shaped bacterium, growing in aerobic conditions and belonging to the Flavobacteriaceae family. The major fatty acids detected are 13-methyl-tetradecanoic acid (57%), 15-methylhexadecenoic acid (18%) and 12-methyl-tetradecanoic acid (8%). Marseille-P9602 strain size was found from genome assembly to be of 4,271,905 bp, with a 35.5% G + C content. The highest values obtained for Ortho-ANI and dDDH were 91.67% and 44.60%, respectively. Thus, hereby we unravel that Marseille-P9602 strain is sufficiently different from other closed related species and can be classified as a novel bacterial species, for which we propose the name of Chryseobacterium schmidteae sp. nov. Type strain is Marseille-P9602 (= CSUR P9602 = CECT 30295).
马赛 P9602 是我们从扁形动物 Schmidtea mediterranea 中分离出的一株类似于 Chryseobacterium 的菌株，我们采用分类基因组学方法对其进行了特征描述。我们发现马赛 P9602 菌株与 Chryseobacterium scophthalmum LMG 13028 菌株的 16S rRNA 基因序列相似度为 98.76%，是其最接近的系统发育近缘种。马赛 P9602 菌株呈黄色素，革兰氏阴性，杆状，需在有氧条件下生长，属于黄杆菌科。检测到的主要脂肪酸为 13-甲基十四烷酸（57%）、15-甲基十六烯酸（18%）和 12-甲基十四烷酸（8%）。马赛 P9602 菌株的基因组组装大小为 4,271,905 bp，G+C 含量为 35.5%。获得的 Ortho-ANI 和 dDDH 的最高值分别为 91.67%和 44.60%。因此，我们揭示马赛 P9602 菌株与其他密切相关的物种有足够的差异，可以归类为一个新的细菌物种，我们将其命名为 Chryseobacterium schmidteae sp. nov. 模式菌株为马赛 P9602（=CSUR P9602=CECT 30295）。
