\n
A consensus has developed among scientific experts that, given the genetic makeup of these bacteria, the current genus Lactobacillus<\/em> was too diverse and did not conform to nomenclature conventions. In addition, it was important to divide the genus into functionally relevant groups that shared certain physiological, metabolic and lifestyle properties in order to facilitate functional and ecological studies on bacteria of this genus. <\/span><\/div>\n
To solve this problem, 15 scientists from 12 different institutions and 7 countries came together, applying whole genome analysis to analyze each species of Lactobacillus<\/em>. <\/span><\/span>Scientists proposed a new classification of the genus Lactobacillus scattering the species of the Lactobacillaceae<\/em>family under\u00a0L. delbrueckii <\/em>and Paralactobacillus <\/em>and 23 novel genera (Zheng et al., 2020), based on several genetic approaches and markers (average nucleotide identity, average aminoacid identity, core-gene aminoacid identity, core genome phylogeny, signature genes and metabolic or ecologic criteria).<\/div>\n
<\/div>\n<\/div>\n
Here are some exemples of the changes:<\/div>\n
