Founded in 1997 by Jean P. Euzéby.
The List of Prokaryotic names with Standing in Nomenclature (LPSN) provides comprehensive information on the nomenclature of prokaryotes and much more. Navigating LPSN is easy.
LPSN is a free to use service founded by Jean P. Euzéby in 1997 and later on maintained by Aidan C. Parte.
IN MEMORY OF JEAN PAUL EUZÉBY (1949-2025)
On 1 January 1997, French veterinary microbiologist Jean Paul Euzéby publicly announced LPSN. He won several awards for his highly popular, comprehensive and meticulously curated resource. Here at DSMZ, we take pride in continuing his work, and we have done our utmost to preserve all of his insightful comments on the new LPSN website, which he spoke fondly of. Alongside his work on LPSN, Prof. Euzéby served as a list editor and nomenclature reviewer for the IJSEM, contributing significantly to the field of prokaryotic nomenclature. He was the recipient of Bergey’s Award in 2005 and became a Life Member of the ICSP upon his retirement in 2013. The following taxa were named after him: Euzebya Kurahashi et al. 2010, Euzebyaceae Kurahashi et al. 2010, Euzebyales Kurahashi et al. 2010, Euzebyella Lucena et al. 2010 and Salinirhabdus euzebyi Albuquerque et al. 2007. An editorial honouring his service to the IJSEM was published on the occasion of his retirement. Our heartfelt condolences go out to Prof. Euzéby’s family and friends.
As of February 2020, the regularly augmented LPSN database at DSMZ is the basis of this new LPSN service. The new database was implemented for the Type-Strain Genome Server and augmented in 2018 to store all kinds of nomenclatural information. Data from the previous version of LPSN and from the Prokaryotic Nomenclature Up-to-date (PNU) service were imported into the new system. PNU had been established in 1993 as a service of the Leibniz Institute DSMZ, and was curated by Norbert Weiss, Manfred Kracht and Dorothea Gleim.
As of December 2023, LPSN is recognized as Global Core Biodata Resource.
