FIG. 1.
rplB gene-based phylogenetic analysis using the neighbor-joining method and based on a Jukes-Cantor distance matrix. Bootstrap values obtained after 1,000 replicates are given at the nodes. The 52 L. casei (L. paracasei) study strains clearly grouped into a compact cluster together with L. casei strain CIP107868 (= ATCC 334). This cluster was clearly distinct from L. rhamnosus and from a cluster with L. zeae and CIP103137T (= ATCC 393T), as well as from all other included reference or type strains.
