  • Notes:
    • 📧 The e-mail address of the corresponding author given in the effective publication is not functional any more.
    • ❗ Clostridium thermoalcaliphilum 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 2026-08-13. 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 the genus.
    • 🧍 According to Ludwig et al. (2021), this "species together with C. paradoxum are susceptible to being reclassified as a new genus within the Peptostreptococcaceae". Publication: Ludwig W, Viver T, Westram R, Francisco Gago J, Bustos-Caparros E, Knittel K, Amann R, Rossello-Mora R. Release LTP_12_2020, featuring a new ARB alignment and improved 16S rRNA tree for prokaryotic type strains. Syst Appl Microbiol 2021; 44:126218. 🇪🇸
