  • Beschreibung: A slightly curved, rod-shaped marine bacterium, designated strain CL-S1T, was isolated from near Dokdo, an island in the East Sea, Korea. Cells were Gram-negative and grew well under either aerobic or microaerobic conditions. Analyses of the 16S rRNA and gyrA gene sequences of strain CL-S1T revealed an affiliation with the genus Arcobacter within the class Epsilonproteobacteria. Phylogenetic analyses based on 16S rRNA and gyrA gene sequences showed that strain CL-S1T formed a robust clade with Arcobacter halophilus LA31BT, with sequence similarities of 96.1 and 88.2 %, respectively. DNA–DNA relatedness between strain CL-S1T and A. halophilus DSM 18005T was 44 %, indicating that they represent genomically distinct species. Strain CL-S1T grew optimally at 30–37 °C, at pH 7 and in the presence of 3–5 % NaCl. The dominant cellular fatty acids were iso-C15 : 0 2-OH and/or C16 : 1 ω7c (28.4 %), C16 : 0 (26.2 %) and C18 : 1 ω7c (22.3 %). The DNA G+C content of strain CL-S1T was 28 mol%. Strain CL-S1T differed phenotypically from A. halophilus LA31BT based on its ability to grow aerobically at 10 °C and inability to grow under anaerobic conditions. Based on the data presented, strain CL-S1T is considered to represent a novel species of the genus Arcobacter, for which the name Arcobacter marinus sp. nov. is proposed. The type strain is CL-S1T (=KCCM 90072T =JCM 15502T).
