Michael A1 DiChristina, Thomas J.YR 2018 T1 Whole-genome sequencing reveals that Shewanella haliotis Kim et al. 2007 can be considered a later heterotypic synonym of Shewanella algae Simidu et al. 1990 JF International Journal of Systematic and Evolutionary Microbiology, VO 68 IS 4 SP 1356 OP 1360 DO https://doi.org/10.1099/ijsem.0.002678 PB Microbiology Society, SN 1466-5034, AB Previously, experimental DNA–DNA hybridization (DDH) between Shewanella haliotis JCM 14758T and Shewanella algae JCM 21037T had suggested that the two strains could be considered different species, despite minimal phenotypic differences. The recent isolation of Shewanella sp. MN-01, with 99 % 16S rRNA gene identity to S. algae and S. haliotis , revealed a potential taxonomic problem between these two species. In this study, we reassessed the nomenclature of S. haliotis and S. algae using available whole-genome sequences. The whole-genome sequence of S. haliotis JCM 14758T and ten S. algae strains showed ≥97.7 % average nucleotide identity and >78.9 % digital DDH, clearly above the recommended species thresholds. According to the rules of priority and in view of the results obtained, S. haliotis is to be considered a later heterotypic synonym of S. algae . Because the whole-genome sequence of Shewanella sp. strain MN-01 shares >99 % ANI with S. algae JCM 14758T, it can be confidently identified as S. algae ., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002678
