• Notes:
  • 🥇 Nomenclatural type of the genus Citreicella Sorokin et al. 2006. Publication: Sorokin DY, Tourova TP, Muyzer G. Citreicella thiooxidans gen. nov., sp. nov., a novel lithoheterotrophic sulfur-oxidizing bacterium from the Black Sea. Syst Appl Microbiol 2005; 28:679-687.
  • ❗ Citreicella thiooxidans 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 Citreicella.
  • 😷 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 3 times in PubMed until 2025-06-04.
  • 🧍 In the protologue of the effective publication, the strain UNIQEM U 228 is cited as UNIQEM 228. Publication: Euzeby JP. Validation list no. 107. List of new names and new combinations previously effectively, but not validly, published. Int J Syst Evol Microbiol 2006; 56:1-6.
