• Notes:
  • 😢 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. Using the term "phylogenetic data" (or equivalent) for sequence data is not advocated. See the LPSN phylogeny page for details. Publication: Göker M. What can genome analysis offer for bacteria?
