• Notes:
  • ⏰ According to Xin et al. (2022), this species is an earlier heterotypic synonym of Halomicrobium katesii Kharroub et al. 2008. Publication: Xin YJ, Bao CX, Li SY, Hu XY, Zhu L, Wei W, Hou J, Cui HL. Genome-based taxonomy of genera Halomicrobium and Halosiccatus, and description of Halomicrobium salinisoli sp. nov.

  • 🏢 Synonymy of this taxon was mentioned in an IJSEM list. Publication: Oren A, Garrity GM. List of changes in taxonomic opinion no. 36. Notification of changes in taxonomic opinion previously published outside the IJSEM. Int J Syst Evol Microbiol 2022; 72:5413.
  • ❗ Haloarcula mukohataei 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 Haloarcula.

The full classification is: risk group = 1, note = "Animal classification RG: 1 - Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No - Containment level: Containment Level 1". — The risk group for Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 1. — 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 2 times in PubMed until 2025-06-04.
  • 🧍 The etymology of the specific epithet should be changed from N.L. adj. (sic) mukohataei to N.L. gen. n. mukohataei, of Yasuo Mukohata. The correct adjectival form would be mukohatana. — The species Haloarcula mukohataei Ihara et al. 1997 was placed in the genus Haloarcula Torreblanca et al. 1986 on the basis of the similarity of its 16S rRNA gene sequence to the 16S rRNA sequences of the other species of the genus. However, its different polar lipid composition as well as important differences in the 16S RNA signature bases could justify the transfer of this species to a new genus. Publication: Ventosa A. Genus II. Haloarcula Torreblanca, Rodriguez-Valera, Juez, Ventosa, Kamekura and Kates 1986b, 573VP (Effective publication: Torreblanca, Rodriguez-Valera, Juez, Ventosa, Kamekura and Kates 1986a, 98).
