antioxidant effect of lactobacillus acidophilus as a probiotic at different time intervals‏

conclusions the results showed that the effect of l. acidophilus is time-dependent. materials and methods antioxidant biomarkers, such as total antioxidant power (tap), measured with the frap (ferric-reducing ability of plasma) method, were evaluated at 24, 48, and 72 hours. results the results showed that extracts and bacteria of l. acidophilus were able to significantly increase tap after 24 and 72 hours. objectives the antioxidative effect of whole cells and intracellular cell-free extracts of the lactic acid bacteria lactobacillus acidophilus (ptcc 1643) as a probiotic‎ at three different time intervals was investigated. background probiotics are survival microorganisms that, when administered in sufficient amounts, confer health benefits to the host and can be used in an antioxidative role.
