A Gram-reaction-negative, aerobic, non-motile, yellow-pigmented, rod-shaped bacterium, designated strain TH-19T, was isolated from a forest soil sample in Jiangsu province, China. On the basis of 16S rRNA gene sequence similarity, strain TH-19T was shown to belong to the genus Myroides, a member of the phylum Bacteroidetes, and was related to Myroides odoratimimus LMG 4029T (98.7 % similarity), Myroides profundi D25T (98.2 %) and Myroides marinus JS-08T (97.5 %). Strain TH-19T contained menaquinone-6 (MK-6) as the predominant menaquinone, and the dominant fatty acids were iso-C15 : 0 and iso-C17 : 0 3-OH. The DNA G+C content of strain TH-19T was 37.2 mol%. The DNA–DNA relatedness values of strain TH-19T with Myroides odoratimimus JCM 7460T, Myroides profundi D25T and Myroides marinus JS-08T were below 70 %. Based on phenotypic, genotypic and phylogenetic evidence, it is suggested that strain TH-19T represents a novel species of the genus Myroides, for which the name Myroides xuanwuensis sp. nov. is proposed. The type strain is TH-19T ( = CCTCC AB 2013145T = JCM 19200T).
