A Gram-reaction-negative, aerobic, non-motile, yellow-pigmented, rod-shaped bacterium, designated strain TH-19(T), was isolated from a forest soil sample in Jiangsu province, China. On the basis of 16S rRNA gene sequence similarity, strain TH-19(T) was shown to belong to the genus Myroides, a member of the phylum Bacteroidetes, and was related to Myroides odoratimimus LMG 4029(T) (98.7% similarity), Myroides profundi D25(T) (98.2%) and Myroides marinus JS-08(T) (97.5%). Strain TH-19(T) contained menaquinone-6 (MK-6) as the predominant menaquinone, and the dominant fatty acids were iso-C(15 : 0) and iso-C(17 : 0) 3-OH. The DNA G+C content of strain TH-19(T) was 37.2 mol%. The DNA-DNA relatedness values of strain TH-19(T) with Myroides odoratimimus JCM 7460(T), Myroides profundi D25(T) and Myroides marinus JS-08(T) were below 70%. Based on phenotypic, genotypic and phylogenetic evidence, it is suggested that strain TH-19(T) represents a novel species of the genus Myroides, for which the name Myroides xuanwuensis sp. nov. is proposed. The type strain is TH-19(T) ( = CCTCC AB 2013145(T) = JCM 19200(T)).
一株革兰氏反应阴性、需氧、不运动、黄色素、杆状细菌，被命名为 TH-19(T) 菌株，从中国江苏省的森林土壤样本中分离得到。根据 16S rRNA 基因序列相似性，菌株 TH-19(T) 属于拟杆菌门的 Myroides 属，与 Myroides odoratimimus LMG 4029(T)（98.7%相似）、Myroides profundi D25(T)（98.2%相似）和 Myroides marinus JS-08(T)（97.5%相似）最为接近。TH-19(T) 菌株含有menaquinone-6 (MK-6) 作为主要的menaquinone，其主要脂肪酸为 iso-C(15 : 0) 和 iso-C(17 : 0) 3-OH。菌株 TH-19(T) 的 DNA G+C 含量为 37.2 mol%。TH-19(T) 菌株与 Myroides odoratimimus JCM 7460(T)、Myroides profundi D25(T)和 Myroides marinus JS-08(T)的 DNA-DNA 同源性值均低于 70%。基于表型、基因型和系统发育证据，建议菌株 TH-19(T) 代表 Myroides 属的一个新种，命名为 Myroides xuanwuensis sp. nov.。其模式菌株为 TH-19(T)（=CCTCC AB 2013145(T)=JCM 19200(T)）。
