Abstract excerpt
The probiotic efficacy of H. coagulans relies on the bile salt tolerance of its vegetative cells, yet direct evidence linking this trait to intestinal colonization remains limited. This study integrated phenotypic screening, in vitro gastrointestinal simulation, in vivo colonization assays, and comparative genomics to address this gap. Among 50 strains, two highly bile salt-tolerant isolates (ATCC 7050 and...
