In 2021, the ICSP held a formal vote on the three proposals and the third option was chosen.[10]
Type strain
Since 2001, when a new bacterial or archaeal species is described, a type strain must be designated.[11] 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 in at least two different countries.[12] Before 2001, a species could also be typified using a description, a preserved specimen, or an illustration.[11] 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, DSM 30083 by the German Collection of Microorganisms and Cell Cultures, JCM 1649 by the Japan Collection of Microorganisms, and LMG 2092 by the Belgian Coordinated Collections of Microorganisms.[13][14]
When a prokaryotic species cannot be cultivated in the laboratory (and therefore cannot be deposited in a culture collection), it may be given a provisional Candidatus name, but is not considered validly published.[15] Since 2024, these names can be "pro-validly published" and become "pro-legitimate" and "pro-correct". This requires the name to meet most existing requirements for valid publication (and analogously for legitimacy and correctness), except the culture deposition in Rule 30 can be replaced by a living culture not meeting the requirements of Rule 30, a preserved specimen, a sequenced genome deposited on the INSDC, or a single-gene sequence deposited to the INSDC. Pro-legitimate Candidatus names compete with each other for priority, but do not compete with "real" legitimate names.[16]
