a+, plaque formation; −, no plaque formation
bEOP: efficiency of plating. EOP values were calculated by dividing the number of plaques on each tested strain by the number of plaques on the indicator strain (E. coli O157:H7 ATCC 43895). NT means not tested. EOP values are shown as the mean ± SD (n = 3)
