Abstract

A yellow-pigmented bacterial strain, designated T13, was isolated from the rhizosphere soil of collected from Xinjiang, PR China. Cells were rod-shaped, Gram-stain-negative, aerobic and gliding. Strain T13 grew optimally at 25–30 °C and pH 7.0–8.0 with a NaCl tolerance of 0–2 % on Reasoner's 2A agar. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain T13 belonged to the genus within the family and was closely related to KCTC 42884 with a similarity value of 97.4 %. The major polar lipid was phosphatidylethanolamine; the only respiratory quinone was MK-6, and the polyamine profile contained -homospermidine as the major polyamine and a trace amount of spermidine. The major fatty acids were iso-C, ω7 and summed feature 3 (comprising Cω7 or Cω6). The G+C content of the genomic DNA was 34.1 mol%. It is concluded from the phenotypic and genotypic data that strain T13 represents a novel species of the genus , for which the name sp. nov. with the type strain T13 (=KCTC 62874=ACCC 60126) is proposed.
