Author(s): Ryuichi Saito* and Naoki Sato*
Lactiplantibacillus plantarum is commonly used in pharmaceuticals and foodstuffs. Some L. plantarum strains are known as lactic acid bacteria that can inhibit the growth of pathogenic bacteria. A significant reclassification of the genus Lactobacillus was carried out in 2020. However, L. plantarum TO-A, which was isolated and registered in 1997, has not been sufficiently characterized. Therefore, in this study, we conducted a taxonomic re-identification of L. plantarum TO-A and judged that it should be classified as L. plantarum subsp. plantarum. Using in vitro experiments, we also determined that L. plantarum TO-A has a higher lactic acid production capability than other lactic acid bacteria (L. plantarum ATCC14917, L. reuteri NBRC15892, L. gasseri ATCC19992, and L. rhamnosus ATCC53103) and that L. plantarum TO-A inhibits the proliferation of four pathogenic bacteria (Escherichia col..
