To exert their beneficial effects, microorganisms used in live bacteria-containing products must be viable and present certain amounts. In this study, we developed a viability assay based on quantitative PCR coupled with propidium monoazide for the identification enumeration of Lactobacillus acidophilus Bifidobacterium bifidum . order to optimize protocol, thermal inactivation conditions two target PMA concentration inhibiting DNA amplification from dead cells while allowing it were first determined. The viability-PCR protocol was then applied analyze commercial product containing microorganisms. quantities both determined using tested significantly higher than those obtained standard plate count, suggesting presence bacteria but non-culturable physiological state. Moreover, lower amounts detected compared achieved PCR, possibly because samples. Our results suggest that method proposed here is suitable alternative rapid accurate quantification assessment L.
