Notes:
- ⏲ According to Kobayashi et al. (2020), this species is a later heterotypic synonym of Clostridium beijerinckii Donker 1926 (Approved Lists 1980). Publication: Kobayashi H, Tanizawa Y, Sakamoto M, Nakamura Y, Ohkuma M, Tohno M. Reclassification of Clostridium diolis Biebl and Sproer 2003 as a later heterotypic synonym of Clostridium beijerinckii Donker 1926 (Approved Lists 1980) emend. Keis et al. 2001. Int J Syst Evol Microbiol 2020; 70:2463-2466. 🇯🇵
- 🏢 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 4 of the IJSEM. Int J Syst Evol Microbiol 2020; 70:4050-4060.
- ❗ Clostridium diolis 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 Clostridium.
- 😷 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 20 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 risk group of the genus.
- 🧍 In the effective publication, a different DSM accession number is given because the strain was originally a patent strain deposited as Clostridium butyricum DSM 5431. Publication: Euzeby JP. Validation list no. 91. List of new names and new combinations previously effectively, but not validly, published. Int J Syst Evol Microbiol 2003; 53:627-628.
