List of Prokaryotic names with Standing in Nomenclature (LPSN) is an online database that maintains information on the naming and taxonomy of prokaryotes,[1] following the taxonomy requirements and rulings of the International Code of Nomenclature of Prokaryotes.
[2] The database was curated from 1997 to June 2013 by Jean P.
Euzéby.
[3] From July 2013 to January 2020, LPSN was curated by Aidan C.
[2] In February 2020, a new version of LPSN was published as a service of the Leibniz Institute DSMZ, thereby also integrating the Prokaryotic Nomenclature Up-to-date service [4] and since 2022 LPSN is interconnected with the Type (Strain) Genome Server (TYGS), a high-throughput platform for accurate genome-based taxonomy [5]
