ATP/ADP alteration as a sign of the oxidative stress development in Escherichia coli cells under antibiotic treatment.

abstract：:While there is strong evidence showing that many food-borne probiotics regulate cholesterol metabolism, few studies have examined how probiotics of human origin affect cholesterol metabolism. Because people living in so-called 'longevity villages' are unlikely to have hypercholesterolemia, we hypothesized that probiot...
