Prokaryotic names

Since decades the Leibniz Institute DSMZ offers the service Prokaryotic Nomenclature up-to-date (PNU), which provides a compilation of all names of Bacteria and Archaea that have been validly published according to the International Code of Nomenclature of Prokaryotes. In February 2020 this database was merged with the renowned List of Prokaryotic names with Standing in Nomenclature (LPSN). The combined database tracks all changes in the nomenclature of Prokaryotes by analysing publications in the International Journal of Systematic and Evolutionary Microbiology (IJSEM) and elsewhere. Data can be accessed by browsing the hierarchy, by using the advanced search, or by downloading a table containing the complete list of validly published names. LPSN includes information on names, synonyms, publications, nomenclatural types and sequences. For programmatic access, a web service is available, which is free after registration.
