• Notes:
  • 🧕 Xu et al. (2011) assigned this genus to the family Hyphomicrobiaceae Babudieri 1950 (Approved Lists 1980). Publication: Xu XW, Huo YY, Wang CS, Oren A, Cui HL, Vedler E, Wu M. Pelagibacterium halotolerans gen. nov., sp. nov. and Pelagibacterium luteolum sp. nov., novel members of the family Hyphomicrobiaceae. Int J Syst Evol Microbiol 2011; 61:1817-1822.
  • 😢 The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. Contrasting the term "chemotaxonomic" with "phenotypic" is not recommended. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details. Publication: Göker M.
