| Abstract |
A novel Gram-negative, oxidase- and catalase-positive, rod-shaped bacterium, designated strain KX21116T, was isolated from the mussel Gigantidas platifrons collected from a cold seep field in the South China Sea. Strain KX21116T grew optimally at 28 °C, pH 6.0 with 3% (w/v) NaCl, under aerobic and microaerobic conditions. Its genome size was 3.16 Mb, with a G+C content of 28.4 mol%. The 16S rRNA sequences revealed that strain KX21116T was closely related to Arcobacter nitrofigilis DSM 7299T (98.77% gene sequence similarity) and Arcobacter acticola AR-13T (95.58%). Phylogenetic and phylogenomic analysis revealed that strain KX21116T clustered with the type species of the genus Arcobacter, with A. nitrofigilis DSM 7299T as its nearest neighbour. The genomic average nucleotide identity (orthoANI) values between strain KX21116T and A. nitrofigilis DSM 7299T were 92.74%, while the in silico DNA-DNA hybridization (GGDC) values of the two strains were 48.8%. The predominant fatty acids are C16:0, C16:1 ω7c/C16:1 ω6c and C18:1 ω7c/C18:1 ω6c. Based on a comparative analysis of phylogenetic, phylogenomic, phenotypic and chemotaxonomic characteristics, strain KX21116T represents a novel species of the genus Arcobacter, for which the name Arcobacter iocasae sp. nov. is proposed. The type strain is KX21116T (=MCCC 1K08505T=KCTC 92900T=JCM 35939T).
