Abstract

A novel Gram-stain-negative, catalase- and oxidase-positive, facultatively anaerobic, and rod-shaped motile bacterial strain, designated as YLB-11, was isolated from seahorse intestine. The 16S rRNA gene sequencing analysis showed that YLB-11 was most closely related LMG 19157 (98.9 % nucleotide sequence identity). Phylogenetic analysis placed strain YLB-11 within the genus . The major cellular fatty acids were summed feature 3 (C 6/C 7, 36.4 %), C (19.1 %) and summed feature 8 (C 6/C 7, 12.3 %). The DNA G+C content of YLB-11 was 44.7 mol %. The DNA–DNA hybridization and average nucleotide identity values for whole-genome sequence comparisons between YLB-11 and related species were clearly below the thresholds used for the delineation of a novel species. Therefore, YLB-11 is considered to represent novel species of the genus , for which the name sp. nov. is proposed. The type strain is YLB-11 (=MCCC 1A17441=KCTC 72604).
