Validation of publication of new names and new combinations previously effectively published outside the IJSB

This validation list formally registers eleven new bacterial names and combinations that were previously published outside the International Journal of Systematic Bacteriology. The list includes five new species: Alterococcus agarolyticus (a halophilic, thermophilic, agar-degrading bacterium), Desulfovibrio aminophilus (an amino acid-degrading sulfate reducer), Desulfovibrio senezii (a halotolerant sulfate reducer), Haemophilus felis (isolated from cats), and Methylobacterium thiocyanatum (capable of growth on thiocyanate). Three new genera are validated: Alterococcus, Moritella, and Thermocrinis. Additionally, Moritella marina is registered as a new combination from the former Vibrio marinus. Two more Moritella species are included: M. japonica (a barophilic bacterium from deep-sea sediments) and Shewanella violacea (also barophilic). Thermocrinis ruber is a pink-filament-forming hyperthermophile from Yellowstone. Valid publication dates from this list, not original publications, establish nomenclatural priority. The validation process ensures standardization in bacterial taxonomy while noting that inclusion does not constitute taxonomic acceptance, as organisms may later be reclassified or shown to be synonyms.

Key findings

• Eleven new bacterial names and combinations validated, including five new species across existing and novel genera
• Three new bacterial genera established: Alterococcus, Moritella, and Thermocrinis, with diverse environmental sources
• Species identified include thermophilic, halophilic, barophilic, and deep-sea adapted bacteria from various environments
• Valid publication date established as the validation list date, not the original publication date, for nomenclatural priority purposes
• Validation reflects increasing bacterial diversity discovery with specialized metabolic capabilities and extreme habitat adaptation
