• Notes:
  • 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Strepacidiphilus"; "Streptacidiphi"; "Streptacidophilus"; "Streptoacidiphilus"; "Syreptacidiphilus".
  • 💁 Taxonomists who have recently focused on this group are the corresponding authors of Golinska et al. (2016), Roh et al. (2018), Yu et al. (2021). Editors in search of reviewers are advised to consider additional criteria such as whether a taxon is covered by one of the ICSP subcommittees.
  • 😢 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. The expression "monophyletic clade" is a pleonasm. 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.
  • 🎰 The BRCs most frequently used for deposits in this group are: DSM: 15; JCM: 12; KCTC: 10; NBRC: 8; NCIMB: 5; CGMCC: 4; NRRL: 3; ATCC: 2; KACC: 2; NEAU: 2.
