^aPurple color indicator for hydrogen peroxide production visible (+) or not visible (−) around colonies on ABTS agar
^bIC50 values shown indicate the concentration of inhibitor (mean of triplicate experiments ± standard deviations) that led to 50 % growth reduction. For out of-out-range values the upper or lower concentration limits tested are shown. L. johnsonii ATCC 33200 (Lj), RC14, and LGG are included as reference strains
