Abstract

A salmon-red-pigmented bacterial strain, designated M-8^T, was isolated from a polluted farmland soil sample in China and was characterized in a taxonomic study using a polyphasic approach. Strain M-8^T was Gram-stain-negative, rod-shaped, non-motile and non-spore-forming. Growth occurred at 20–37 °C, at pH 5.0–10.0 and with 0–2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain M-8^T belonged to the genus Terrimonas.16S rRNA gene sequence similarity values between strain M-8^T and the type strains of the three recognized species of the genus Terrimonas, Terrimonas ferruginea KACC 11310^T, Terrimonas aquatica LMG 24825^T and Terrimonas lutea KACC 13047^T, were 97.1, 96.3 and 95.3 %, respectively. The predominant respiratory quinone was menaquinone-7 (MK-7) and the major fatty acids were iso-C_15 : 0, iso-C_17 : 0 3-OH and summed feature 3 (comprising C_16 : 1ω7c and/or C_16 : 1ω6c). The DNA G+C content of strain M-8^T was 47.0 mol%. On the basis of genotypic and phenotypic data, strain M-8^T is considered to represent a novel species of the genus Terrimonas, for which the name Terrimonas rubra sp. nov. is proposed. The type strain is M-8^T ( = CCTCC AB 2010401^T = KCTC 23299^T). An emended description of the genus Terrimonas is also presented.
