• Notes:
  • ⏲ According to Patel et al. (2024), this species is not a later heterotypic synonym of Saccharococcus thermophilus Nystrand 1984. Publication: Patel I, Bello S, Gupta RS. Phylogenomic and molecular marker based studies to clarify the evolutionary relationships amongst Anoxybacillus species and demarcation of the family Anoxybacillaceae and some of its constituent genera. Int J Syst Evol Microbiol 2024; 74:6528.
  • 🏢 Synonymy of this taxon was mentioned in an IJSEM list. Publication: Oren A, Göker M. Notification list. Notification that new names and new combinations have appeared in volume 74, part 9 of the IJSEM. Int J Syst Evol Microbiol 2024; 74:6556.
  • 😢 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. The phrase "validly described" is misleading. 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.
  • ❗ Geobacillus caldoxylosilyticus is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Geobacillus.
  • 😷 The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 1. — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
  • 🎓 Name mentioned 11 times in PubMed until 2025-06-04.
