The IPA Scientific Committee wrote a blog about this when Lactobacillus<\/em> decided it didn\u2019t want to be such a huge genus any longer. Published in 2020 was the research on the how and why this name change was needed. A taxonomic note on the genus Lactobacillus<\/em>.<\/a><\/p>\n\n\n\n Just to clarify that the real purpose of naming or classifying (living) things is to improve communication, The biodiversity around us is huge: plants, insects and spiders; cats, dogs and horses; bacteria, yeasts and fungi. They are part of our daily life and part of our dear body. We like to know what we are dealing with 24h a day, so we need to be able to talk and communicate about it. That is why Nomenclature was invented.<\/p>\n\n\n\n Recent adoptions on the QPS list by EFSA\u2026 read more here<\/strong><\/p>\n\n\n\n In 2020 there were over 280 species of the genus Bacillus <\/em>(>390 when counting synonyms). As the genus Lactobacillus <\/em>before, this was considered a \u201ctaxonomic anomaly\u201d!. The genus Bacillus<\/em> was roughly divided in two clades, the B. subtilis<\/em> clade and the B. cereus<\/em> clade (containing the pathogens B. anthracis <\/em>and B. cereus<\/em>). Using the sequence of over 300 genomes, Gupta and coworkers (1) showed the presence of another 17 new, distinct clades. Based on a strong phylogenetic and molecular base, all 17 Bacillus<\/em> clades were given a new genus name (Alteribacter, Ectobacillus, Evansella, Ferdinandcohnia, Gottfriedia, Heyndrickxia, Lederbergia, Litchfieldia, Margalitia, Niallia, Priestia, Robertmurraya, Rossellomorea, Schinkia, Siminovitchia, Sutcliffiella <\/em>and Weizmannia<\/em>). The species Robertmurraya kyonggiensis<\/em> was also created for Bacillus kyonggiensis<\/em>. Results furthermore pointed to other misnamed Bacillus<\/em> species, which consequently were transferred to genera like Alkalicoccus, Caldalkalibacillus, Caldibacillus, Salibacterium<\/em> and Salisediminibacterium<\/em>.<\/p>\n\n\n\n The advantage of this subdivision, as for the earlier spilt of the genus Lactobacillus<\/em> (2) is the more comprehensive separation of potential pathogenic species with species that have a safe history of use in foods.<\/p>\n\n\n\n
