Minimal Standards

See the glossary entry on minimal standards for the description of new taxa for details, as well as Appendix 6 of the International Code of Nomenclature of Prokaryotes (2008 revision), Int J Syst Evol Microbiol 2019; 69:S1-S111. A list of minimal standards published by taxonomic subcommittees is provided below together with associated publications and assorted by the group of organisms to which each one applies. Note that more recently published proposals for minimal standards may supersede older proposals. The list also includes minutes of the meeting of the same taxonomic subcommittees. The website of the ICSP also contains information on taxonomic subcommittees.
