Abstract

A Gram-negative, motile, rod-shaped, and aerobic bacterial strain, designated LPB0072, was isolated from a Pacific oyster (). Autotrophic growth with hydrogen gas was not observed. Cells oxidized thiosulfate to sulfate and reduced nitrate to nitrite. The complete genome sequence of strain LPB0072 (CP017476) is 4.94 Mb in length and contains 4459 protein-coding genes, with a G+C content of 61.3 mol%. Analysis of the 16S rRNA gene sequence indicated that strain LPB0072 belongs to the genus with greatest sequence similarity to the type strain of (97.5 %). The isoprenoid quinone (Q-8) and the major cellular fatty acids (Cω and/or Cω, C and Cω) identified were concordant with the chemotaxonomic properties of the genus . The average nucleotide identities with closely related species were below the suggested boundary for species delineation, indicating that the isolate is a novel species. Numerous physiological and biochemical features also distinguished the isolate from other known species. Based on the polyphasic data presented in this study, strain LPB0072 should be classified as a novel species in the genus and the name sp. nov. is proposed. The type strain is LPB0072 (=KACC 18705=JCM 31188).
