  • 🎓 Name mentioned 5 times in PubMed until 2026-06-11.
  • 🧍 Should have been regarded as not validly published because, at the time of publication, the type strain was not deposited in two publicly accessible service collections in different countries. However, additional deposits of the type strain were established in the meantime. Publication: Oren A, Arahal DR, Christensen H, Goker M, Manaia CM, Moore ERB.

  • 🧍 According to Rules 27(3) and 30, Chlorobium luteolum (Schmidle 1901) Imhoff 2003 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.
