Ability of Bifidobacterium breve to grow on different types of milk: exploring the metabolism of milk through genome analysis.

We have investigated the occurrence of bifidobacteria in human milk samples, and we provide evidence regarding the predominance of members of the Bifidobacterium breve species in this environment. Moreover, evaluation of the growth capabilities and transcriptomic analyses of one representative isolate of this species, i.e., B. breve 4L, on different milk types were performed.
