In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, bot ...

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among ...

Archaea ( ; singular archaeon ) is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebac ...

. An early Code for the nomenclature of bacteria was approved at the 4th International Congress for Microbiology in 1947, but was later discarded.
The latest version to be printed in book form is the 1990 Revision, but the book does not represent the current rules. The 2008 Revision has been published in the ''

The baseline for bacterial names is the Approved Lists with a starting point of 1980. New bacterial names are reviewed by the ICSP as being in conformity with the Rules of Nomenclature and published in the ''IJSEM''.
Cyanobacteria
Since 1975, most bacteria were covered under the bacteriological code. However, cyanobacteria
Cyanobacteria (), also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name ''cyanobacteria'' refers to their color (), which similarly forms the basis of cyanobacteria's common name, blu ...
were still covered by the botanical code. Starting in 1999, cyanobacteria were covered by both the botanical and bacteriological codes. This situation has caused nomenclatural problems for the cyanobacteria. By 2020, there were three proposals for how to resolve the situation:
# Exclude cyanobacteria from the bacteriological code.
# Apply the bacteriological code to all cyanobacteria.
# Treat valid publication under the botanical code as valid publication under the bacteriological code.
In 2021, the ICSP held a formal vote on the three proposals and the third option was chosen.
Type strain
Since 2001, when a new bacterial or archaeal species is described, a type strain must be designated.[Prokaryotic Code (2008 Revision)](_blank)
Rule 18a. The type strain is a living culture to which the scientific name of that organism is formally attached. For a new species name to be validly published, the type strain must be deposited in a public culture collection
A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions. Microbial cultures are foundational and basic diagn ...
in at least two different countries.[Prokaryotic Code (2008 Revision)](_blank)
Rule 30. Before 2001, a species could also be typified using a description, a preserved specimen, or an illustration. There is a single type strain for each prokaryotic species, but different culture collections may designate a unique name for the same strain. For example, the type strain of '' E. coli'' (originally strain U5/41) is called ATCC 11775 by the American Type Culture Collection
