• Notes:
  • 📠 This subspecies was automatically created by the valid publication of Clostridium estertheticum subsp. laramiense (Kalchayanand et al. 1993) Spring et al. 2003 according to rule 40d. Publication: Spring S, Merkhoffer B, Weiss N, Kroppenstedt RM, Hippe H, Stackebrandt E. Characterization of novel psychrophilic clostridia from an Antarctic microbial mat: description of Clostridium frigoris sp. nov., Clostridium lacusfryxellense sp. nov., Clostridium bowmanii sp. nov. and Clostridium psychrophilum sp. nov. and reclassification of Clostridium laramiense as Clostridium estertheticum subsp. laramiense subsp. nov.

  • ❗ Clostridium estertheticum subsp. estertheticum is the correct name instead if this subspecies is regarded as a separate subspecies (i.e., if its nomenclatural type is not assigned to another subspecies whose name is validly published, legitimate and not rejected and has priority) within a separate species Clostridium estertheticum 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.
  • 🙆 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as the name to be applied to this subspecies. The name is on LoRN because of the recorded risk group of the genus.
