Bacillus Reclassification – Keeping Up With Microbial Taxonomy

Updates to Accugenix® Microbial Databases for Identifications

We’re committed to providing the most accurate identifications to the industries we serve. This commitment requires that we continuously update our validated Accugenix® microbial databases to stay current with the evolving microbial world, where taxonomic changes and new species are described daily.

Until recently, the genus Bacillus comprised over 500 species. In 2020, there were multiple publications noting large reclassifications and taxonomic changes to the genus Bacillus. While the nomenclature changes seem extensive involving the renaming of hundreds of Bacillus species into more than 30 new genera, there is no reclassification in the groups of Bacilli that are most familiar and frequently recovered during environmental monitoring – the Bacillus cereus and Bacillus subtilis clades.

To ensure we continually provide the best identification services and validated microbial databases or MALDI-TOF and sequence databases, we routinely evaluate our identification rate for customers' bacterial and fungal samples. Since our objective is to achieve the highest percentage of species-level identifications, we compare sample microbial sequence data that do not result in a species-level match against a variety of publicly available sequence databases. If a newly described organism is a good match for those sample sequences and is validly named and published, the sequence proceeds to our validated MALDI-TOF and sequence database entry process, where it undergoes extensive testing and review prior to approval and entry into the Accugenix® microbial database.
