    Notes:
    • 🧍 In the protologue of Methylovorus mays Doronina et al. 2001 emend. Doronina et al. 2005, the type strain NCIMB 13992 is erroneously cited as NCIMB 13922.

• Notes:
  • 😷 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 15 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, Methylovorus mays Doronina et al. 2001 is considered to be validly published, since deposit in a second culture collection in a different country has been documented.
