Abstract

A salmon-red-pigmented bacterial strain, designated M-8, was isolated from a polluted farmland soil sample in China and was characterized in a taxonomic study using a polyphasic approach. Strain M-8 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 belonged to the genus .16S rRNA gene sequence similarity values between strain M-8 and the type strains of the three recognized species of the genus , KACC 11310, LMG 24825 and KACC 13047, 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, iso-C 3-OH and summed feature 3 (comprising Cω7 and/or Cω6). The DNA G+C content of strain M-8 was 47.0 mol%. On the basis of genotypic and phenotypic data, strain M-8 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is M-8 ( = CCTCC AB 2010401 = KCTC 23299). An emended description of the genus is also presented.
