This validation list from the International Journal of Systematic and Evolutionary Microbiology formally publishes nine new bacterial names and combinations that were previously described in other journals. The list includes two new genera (Alkalispirillum and Anaeromyxobacter) and seven new species across various bacterial groups. These names become officially valid for bacteriological nomenclature upon publication of this list, regardless of when they were originally described elsewhere. Each entry includes the proposed name, authoring researchers, priority number based on submission date, and nomenclatural type strain with culture collection accession numbers. The validation process ensures that all nomenclatural requirements have been met before names are recognized in bacterial taxonomy. It is emphasized that valid publication through this list does not constitute taxonomic acceptance, as organisms may later be reclassified or names may prove to be synonyms.

Key findings

• Nine new bacterial taxa were formally validated including Alkalispirillum mobile, Anaeromyxobacter dehalogenans, and species of Desulfovibrio, Enterococcus, Lactobacillus, Leptospirillum, Thermaerobacter, and Tsukamurella
• Valid publication date is established as the date this validation list was published in 2002, not the dates of original descriptions in other journals
• All validated names include designated type strains deposited in recognized international culture collections with specific accession numbers
• Validation does not imply taxonomic acceptance and names may later be synonymized or organisms transferred to different genera
