BIFIDOBACTERIA: ISOLATION, IDENTIFICATION AND USE IN PROBIOTIC FOODS This review aimed to describe the main culture media that have been developed for the isolation and enumeration of bifidobacteria and the molecular methods used for identification of this genus and its species. The criteria for probiotic bifidobacteria selection for their technological application were also demonstrated (as tolerance to low pH, presence of oxygen and presence of ingredients and additives). Various studies
