Myroides xuanwuensis sp. nov., a mineral-weathering bacterium isolated from forest soil.

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)).
