| Abstract |
A novel Gram-staining-negative, catalase- and oxidase-positive, facultatively anaerobic and rod-shaped motile bacterial strain, designated as ZWAL4003T, was isolated from mangrove sediments of the Zini Mangrove Forest, Zhangzhou City, PR China. Phylogenetic analysis based on its 16S rRNA gene sequence indicated that ZWAL4003T was grouped into a separated branch with Vibrio plantisponsor MSSRF60T (97.38% nucleotide sequence identity) and Vibrio diazotrophicus NBRC 103148T (97.27%). The major cellular fatty acids were C14 : 0 (12.6%), C16 : 0 (17.6%), and summed feature 3 (C16 : 1ω6c /C16 : 1 ω7c, 45.6%). Its genome had a length of 4650556 bp with 42.8% DNA G+C content, and contained genes involved in the biosynthesis of bacteriocin, β-lactone, resorcinol, N-acyl amino acid, and arylpolyene. The in silico DNA-DNA hybridization and average nucleotide identity values for whole-genome sequence comparisons between ZWAL4003T and V. plantisponsor LMG 24470T were clearly below the thresholds used for the delineation of a novel species. The morphological and chemotaxonomic characteristics and the genotypic data of ZWAL4003T indicated that it represented a novel species of the genus Vibrio. Its proposed name is Vibrio ziniensis sp. nov., and the type strain is ZWAL4003T (=KCTC 72971T=MCCC 1A17474T).
