Abstract

A yellow, Gram-stain-negative, aerobic, non-gliding, non-spore-forming, rod-shaped strain, designated YIM 102600, was isolated from the faeces of dwelling in the Yunnan Wild Animal Park, Yunnan Province, South-West PR China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM 102600 was a member of the genus , and closely related to F3 (96.9 % similarity) and R-HLS-17 (96.0 % similarity). Phylogenetic trees showed that strain YIM 102600 formed a clade with F3 and R-HLS-17. Growth occurred at 4–30 °C (optimum, 28 °C), pH 7.0–8.0 (pH 7.5) and NaCl concentration 0–2 % (w/v; 0–1 %, w/v). The major fatty acids were iso-C and summed feature 3 (comprising C 7 and/or C 6). The predominant polar lipid was phosphatidylethanolamine and the sole respiratory quinone was menaquinone-6. The DNA G+C content was 36.4 mol%. The calculated digital DNA–DNA hybridization values between strain YIM 102600 and other species of ranged from 70.0 to 75.0 % and average nucleotide identity values were in a range between 13.7 to 23.5 %. Based above the consensus of phenotypic and phylogenetic analyses as well as whole genome comparisons, strain YIM 102600 (=KCTC 52099=CCTCC AB 201632) is proposed to represent type strain of a novel species, sp. nov.
