Complete Genome Sequences of Probiotic Strains Bifidobacterium animalis subsp lactis B420 and Bi-07

We present the complete genomes of Bifidobacterium animalis subsp. lactis B420 and Bi-07. Comparative genomic analysis with the type strain DSMZ10140 revealed 40 to 55 single nucleotide polymorphisms (SNPs) and an indel in a clustered regularly interspaced short palindromic repeat (CRISPR) locus. These genetic differences provide a molecular basis for strain typing within the two main phylogenetic groups of this monomorphic species.
