• Notes:
  • 🛺 The type genus of this family has been placed in the family Caldifarciminaceae Mori et al. 2026. Publication: Mori K, Hidaka K, Tamazawa S, Hosoyama A, Tamaki H, Kakegawa T, Hanada S. Caldifarcimen microaerophilum gen. nov., sp. nov., a facultatively anaerobic, thermophilic bacterium of a novel bacterial phylum, Caldifarciminota phyl. nov., formerly called candidate phylum WOR-3, description of Caldifarciminaceae fam. nov., Caldifarciminales ord. nov. and Caldifarciminia classis nov.

  • 🧍 The article mentions the SeqCode. This SeqCode is not an officially recognized code of nomenclature. In fact, the use of the SeqCode is officially discouraged. ICNP-compliant databases and publications are not allowed to use the SeqCode. The SeqCode deliberately and systematically violates the ICNP. The SeqCode attempts to undermine the scientific standard called "valid publication of the name of a prokaryote" by lowering the requirements compared to the ICNP, but using the same term and assigning it to names whose formation is indistinguishable from the one used by the ICNP. LPSN follows the ICNP and treats such names as not validly published. Publication: Goker M, Moore ERB, Oren A, Trujillo ME.
