  • 🥇 Nomenclatural type of the genus "Candidatus Magnetococcus" Lefèvre et al. 2012. Publication: Lefevre CT, Viloria N, Schmidt ML, Posfai M, Frankel RB, Bazylinski DA. Novel magnetite-producing magnetotactic bacteria belonging to the Gammaproteobacteria. ISME J 2012; 6:440-450.
  • ❗ "Candidatus Magnetococcus marinus" is the pro-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 and legitimate or pro-validly published and pro-legitimate and not rejected and has priority or pro-priority) within a separate genus "Candidatus Magnetococcus".
  • 😷 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.
  • 🧍 This species was confirmed as the type species of its monotypic genus in Appendix 1 of Candidatus List No. 6.
