aOne unit is defined as 1 mm2 of the zone of inhibition as determined by the well-diffusion method (see text). Data are the average of triplicate assays. A value of “0” indicates no inhibition. bBacterium used as positive control. It was used to determine the units of bacteriocins contained in the crude extracts used in the assay [17, 18]. |
