The List of Prokaryotic names with Standing in Nomenclature (LPSN): A Guide to Microbial Taxonomy
In the vast and complex world of microbiology, precision in naming is essential for scientific communication. To ensure that researchers globally are referring to the same organisms, the List of Prokaryotic names with Standing in Nomenclature (LPSN) serves as the definitive online database for the naming and taxonomy of prokaryotes—single-celled organisms that lack a membrane-bound nucleus, such as bacteria and archaea.
The LPSN is not merely a list but a curated resource that adheres strictly to the requirements and rulings of the International Code of Nomenclature of Prokaryotes. By providing a centralized authority on valid names, it prevents confusion and maintains stability in microbial classification.
Key Facts
- Purpose: Maintains official naming and taxonomic information for prokaryotes.
- Standard: Follows the International Code of Nomenclature of Prokaryotes.
- Current Host: Managed as a service of the Leibniz Institute DSMZ.
- Key Integration: Interconnected with the Type (Strain) Genome Server (TYGS) since 2022.

The Evolution and Curation of LPSN
The LPSN has evolved through several stages of curation to keep pace with the growing volume of microbial discoveries. Since its inception in 1997, the database has been maintained by leading experts in the field to ensure scientific accuracy.
From 1997 until June 2013, the database was curated by Jean P. Euzéby. Following this period, Aidan C. Parte took over curation duties from July 2013 through January 2020. This continuity of expert oversight ensured that the database remained a reliable reference for the scientific community during a period of rapid taxonomic change.
Transition to the Leibniz Institute DSMZ
In February 2020, the LPSN entered a new era when it was published as a service of the Leibniz Institute DSMZ. This transition allowed for the integration of the Prokaryotic Nomenclature Up-to-date service, further streamlining the process of updating microbial names and classifications.
Modern Integration and Genome-Based Taxonomy
As microbiology shifts toward genomic data, the LPSN has adapted by integrating with advanced technological platforms. In 2022, the database became interconnected with the Type (Strain) Genome Server (TYGS).
TYGS is a high-throughput platform designed for accurate genome-based taxonomy. By linking the official nomenclature of the LPSN with the genomic data provided by TYGS, scientists can now achieve faster and more reliable classification of prokaryotes based on their genetic blueprints rather than relying solely on traditional phenotypic characteristics.
