Notes:
- ⏰ According to Kwak et al. (2020), this species is an earlier heterotypic synonym of Paenibacillus jamilae Aguilera et al. 2001. Publication: Kwak MJ, Choi SB, Ha SM, Kim EH, Kim BY, Chun J. Genome-based reclassification of Paenibacillus jamilae Aguilera et al. 2001 as a later heterotypic synonym of Paenibacillus polymyxa (Prazmowski 1880) Ash et al. 1994. Int J Syst Evol Microbiol 2020; 70:3134-3138.
- 🏢 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 70, part 5 of the IJSEM. Int J Syst Evol Microbiol 2020; 70:4421-4424.
- ❗ Bacillus polymyxa 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 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 301 times in PubMed until 2025-06-04.
- 🙅 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 pathogenicity of the species itself.
