Fig. 2.

Phylogenomic tree of the genus Bifidobacterium based on the concatenation of 233 core gene (and derived protein) sequences from genomes of novel isolates 2028B and 2034B, and 69 type strains of the genus Bifidobacterium. The amino acid-deduced core gene-based tree highlights the division into 10 phylogenetic groups represented by different colors. The phylogenetic tree was constructed by the neighbor-joining method, with the genome sequence of Scardovia inopinata JCM 12537 as outgroup. Bootstrap percentages above 50 are shown at node points, based on 1000 replicates of the phylogenetic tree
