To pre-challenge lactic acid bacteria with simulated gastrointestinal conditions is a suitable approach to studying potential probiotic properties

The potential probiotic properties of lactic acid bacteria (LAB) after treatment with gastrointestinal (GI) conditions were investigated. Some LAB strains that survived simulated GI treatment retained their adhesiveness and antagonism against the pathogen. Therefore pre-challenging LAB with simulate...

Description
Summary:The potential probiotic properties of lactic acid bacteria (LAB) after treatment with gastrointestinal (GI) conditions were investigated. Some LAB strains that survived simulated GI treatment retained their adhesiveness and antagonism against the pathogen. Therefore pre-challenging LAB with simulated GI conditions is a suitable way for potential probiotic studies. •LAB that survived simulated GI treatment had higher adhesiveness than nontreated ones.•LAB that survived simulated GI treatment retained the ability to inhibit the pathogen.•Pretreating LAB with simulated GI conditions is a suitable way for probiotic studies.
