Abstract:Tens of thousands of prokaryotic species/strains have been found and taxonomically designated since the first publication around 340 years ago. Especially in recent years, with the rapid development of molecular biology, numerous emerging taxa have been identified and designated. There is an imminent calling for a systematic summary of the known microorganisms and make appropriate revision of Chinese nomenclature what scientists have revealed, classified and Latinized. This paper tended to summarize the Chinese-Latin bilingual nomenclature for approximate more than 1 500 species in over 350 genera and more than 1 200 species in over 120 genera suffixed with -bacter and -bacterium, respectively, based on their characteristics and arrangement of biotope, morphology including motility, shape and dimension, biochemisty, and taxonomic domain position, i.e. Bacteria or Archaea. Expecting it contribute to promote the development of microorganism taxonomy in China and abroad, and to improve international communication and cooperation.
