• Notes:
  • 🥇 Nomenclatural type of the genus Trichlorobacter De Wever et al. 2001. Publication: De Wever H, Cole JR, Fettig MR, Hogan DA, Tiedje JM. Reductive dehalogenation of trichloroacetic acid by Trichlorobacter thiogenes gen. nov., sp. nov. Appl Environ Microbiol 2000; 66:2297-2301. 🇧🇪
  • ❗ Trichlorobacter thiogenes 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 Trichlorobacter.
  • 😷 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 5 times in PubMed until 2026-06-11.
  • 🧍 According to Rules 27(3) and 30, this name is not validly published, because the original publication makes reference to the deposit of the type strain in a single recognized culture collection. However, according to the Judicial Opinion 81, Trichlorobacter thiogenes De Wever et al. 2001 is considered to be validly published, since deposit in a second culture collection in a different country has been documented.
