Notes:
- 📧 The e-mail address of the corresponding author given in the effective publication is not functional any more.
- ❗ Bacillus thermantarcticus 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 Bacillus.
- 😷 The risk group for Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 1. — 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 4 times in PubMed until 2026-06-11.
- 🙅 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as a synonym of the name to be applied to this species. The name is on LoRN because of the recorded risk group of other species in the genus.
- 🧍 According to Rules 27(3) and 30, this name is not validly published, because the original publication makes reference to the deposit of the type strain in a single recognized culture collection. However, according to the Judicial Opinion 81, Bacillus thermantarcticus corrig. Nicolaus et al. 2002 is considered to be validly published, since deposit in a second culture collection in a different country has been documented. Publication: Euzeby JP, Tindall BJ.

- 🧍 The original spelling of the specific epithet, thermoantarcticus (sic), has been corrected on validation according to Rule 61. Publication: Anonymous. Validation list no. 84.
