• Notes:
  • 🥇 Nomenclatural type of the genus Hahella Lee et al. 2001. Publication: Lee HK, Chun J, Moon EY, Ko SH, Lee DS, Lee HS, Bae KS. Hahella chejuensis gen. nov., sp. nov., an extracellular-polysaccharide-producing marine bacterium. Int J Syst Evol Microbiol 2001; 51:661-666. 🇰🇷
  • 😷 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 44 times in PubMed until 2025-06-04.
  • 🧍 The name was not originally to be regarded as validly published because of the lack of two type-strain deposits in two distinct countries. However, an additional deposit was established in the aftermath. Publication: Oren A, Arahal DR, Christensen H, Goker M, Manaia CM, Moore ERB. International Code of Nomenclature of Prokaryotes. Prokaryotic Code (2025 Revision). Int J Syst Evol Microbiol 2026; 76:6979. 🇮🇱
  • 🧍 According to Rules 27(3) and 30, Hahella chejuensis Lee et al. 2001 is not validly published because, at the time of publication, the type strain was not deposited in two publicly accessible service collections in different countries. According to the Judicial Opinion 81, authors or this name, or other scientists who wish to have this name validly published, should submit evidence of the deposit of the type strain in additional collections to the List Editor (either directly or via the IJSEM Editorial Office) before the next meeting of the Judicial Commission in Sapporo, Japan, in 2011. After that time, the name will be ruled not to have been validly published. If, after that deadline, the authors or other scientists wish to have this name validly published, this may be done by confirming that the name is in accordance with the requirements of the Code and either by requesting valid publication via the Validation Lists or by inclusion of the proposal in an original article in the IJSEM. The details of valid publication will then make reference to those publications. If authors or other scientists feel that an exception should be granted to Rule 30, requiring deposit of the type in two different collections in two different countries, they should contact the Editorial Office of the IJSEM.
