  • 📧 The e-mail address of the corresponding author given in the effective publication is not functional any more.
  • 😷 The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 1.
  • 🎓 Name mentioned 1 time in PubMed until 2024-03-27.
  • 🧍 An additional deposit (NBRC 106566) was made in 2007. — Thiel V. Personal communication, 2020-05-04.
  • 🧍 According to Rules 27(3) and 30, Chlorobaculum thiosulfatiphilum 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.

  • 🧍 Originally regarded as not validly published because, at the time of publication in the IJSEM in 2003, the type strain was not deposited in two publicly accessible service collections in different countries. This was fixed later on and the name validated by inclusion in a Validation List. Publication: Judicial Commission. Judicial Opinion No. 81. Int J Syst Evol Microbiol 2008; 58:1755-1763.
