Vibrio gangliei sp. nov., a novel member of Vibrionaceae isolated from sawdust in a pigpen.

A Gram-stain-negative, rod-shaped, catalase- and oxidase-positive, facultatively anaerobic, and motile bacterium, designated strain SZDIS-1T, was isolated from pigpen sawdust bedding in Xiamen, Fujian Province, China. Cells grew at 10-50 °C, pH… Click to show full abstract

A Gram-stain-negative, rod-shaped, catalase- and oxidase-positive, facultatively anaerobic, and motile bacterium, designated strain SZDIS-1T, was isolated from pigpen sawdust bedding in Xiamen, Fujian Province, China. Cells grew at 10-50 °C, pH 6.0-9.0, up to 12 % (w/v) NaCl, resisted vibriostatic agent O/129 and were negative for gelatin and alginate hydrolysis. No growth on thiosulfate citrate bile salts sucrose agar medium. Based on 16S rRNA gene sequences and multilocus sequence analysis, this strain should be assigned to the genus Vibrio, with the closest relatives being Vibrio aphrogenes CA-1004T (97.7 % 16S rRNA gene sequence pairwise similarity), Vibrio algivorus SA2T (96.6 %), Vibrio casei WS 4539T (96.3 %), Vibrio rumoiensis S-1T (96.1 %) and Vibrio litoralis MANO22DT (95.5 %), but separate from them by large distances in different phylogenetic trees. Based on whole genome analysis, the orthologous average nucleotide identity and in silico DNA-DNA hybridization values against the five relatives were 76.1-78.7 and 20.1-28.7 %. The major fatty acids were summed feature 3 (C16 : 1ω7c/C16 : 1ω6c), C16 : 0, summed feature 2 (one or more of C12 : 0 aldehyde, C14 : 0 3OH and/or iso-C16 : 1) and summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c). The DNA G+C content was 43.0 mol% from whole genomic sequence analysis. Therefore, phylogenetic, genotypic, phenotypic and chemotaxonomic characteristics showed that the isolate represented a novel species of the genus Vibrio, for which the name Vibrio gangliei sp. nov. is proposed. The type strain is SZDIS-1T (=DSM 104291T=CGMCC 1.15236T).
