Abstract

A Gram-negative, motile, rod-shaped aerobic and alkalogenic bacterium, designated as strain YLCF04, was isolated from chicken faeces. Its growth was optimal at 28 °C (range, 10–40 °C), pH 8 (range, pH 6–9) and in 1 % (w/v) NaCl (range, 0–10 %). It was classified to the genus and was most closely related to CCUG 53761A (97.5 % similarity) based on 16S rRNA gene sequence analysis. Average nucleotide identity and digital DNA–DNA hybridization values between YLCF04 and CCUG 53761A were 76.3 and 18.2 %, respectively. Strain YLCF04 has a genome size of 2.7 Mb with DNA G+C content of 46.3 mol%. Based on its phylogenetic, genomic, phenotypic and biochemical characteristics, strain YLCF04 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is YLCF04 (=CCTCC AB 2022359= KCTC 92789).
