The antimicrobial properties of the lowbush blueberry (Vaccinium angustifolium) fractional components against foodborne pathogens and the conservation of probiotic Lactobacillus rhamnosus

► We discovered fractional components of wild blueberries inhibit intestinal pathogens and conserve probiotic L. rhamnosus. ► Anthocyanins plus proanthocyanidins fraction demonstrated the lowest MICs/MBCs. ► L. monocytogenes was the most susceptible to blueberry fraction treatment, followed by E. coli O157:H7, and S. Typhimurium. ► L. rhamnosus was the least susceptible to each fraction treatment demonstrating the conservation of probiotics. ► The effects of each fractional could be synergistic or cumulative depending on the mechanism of action.
