• Notes:
  • 🧕 He et al. (2021) assigned this genus to the family Rhodospirillaceae Pfennig and Trüper 1971 (Approved Lists 1980). Publication: He W, Li Y, Zhang D. Pacificispira spongiicola gen. nov., sp. nov., a nitrate-reducing bacterium isolated from tropical western Pacific. Antonie Van Leeuwenhoek 2021; 114:2083-2090.
  • 😢 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. What can genome analysis offer for bacteria? In: Bridge P, Smith D, Stackebrandt E (eds), Trends in the systematics of bacteria and fungi, CAB International, Wallingford, 2021, p. 255-281.
