The List of Prokaryotic names with Standing in Nomenclature (LPSN) provides comprehensive information on the nomenclature of prokaryotes and much more.
The Type (Strain) Genome Server (TYGS) closes a gap by providing a publicly available bioinformatics infrastructure. It builds on the established GGDC infrastructure but adds a variety of taxonomically useful facilities. TYGS allows for a genome-based replacement of taxonomic standard techniques such as DNA:DNA hybridization (DDH), G+C-content measurement, 16S rRNA gene sequencing and multi-locus sequence analysis.
