Notes:
- ⏲ According to Liu et al. (2018), this species is a later heterotypic synonym of Bacillus mycoides Flügge 1886 (Approved Lists 1980). Publication: Liu Y, Lai Q, Shao Z. Genome analysis-based reclassification of Bacillus weihenstephanensis as a later heterotypic synonym of Bacillus mycoides. Int J Syst Evol Microbiol 2018; 68:106-112. 🇨🇳
- 🏢 Synonymy of this taxon was mentioned in an IJSEM list. Publication: Oren A, Garrity GM. Notification list. Notification that new names and new combinations have appeared in volume 68, part 1 of the IJSEM. Int J Syst Evol Microbiol 2018; 68:979-981.
- ❗ Bacillus weihenstephanensis 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 phylogenomic assignment score of this taxon is -0.05457 (N = 95).
- 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "Animal classification RG: 1 - Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No - Containment level: Containment Level 1". — 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 = 2. — 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.

- 🥱 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 the species itself. This name is not taxonomically suspended any more (but still isn't preferred) in favour of Bacillus cereus Frankland and Frankland 1887 (Approved Lists 1980). Publication: Frankland GC, Frankland PF.
