Bacteriocin activity can be quantified by a simple parallel line model based on an agar diffusion assay. The quotient between the inhibition zone area and the sensitivity of the indicator bacterium can be used to compare different bacteriocins. Deferred calculations of relative potencies are possible, once purified compounds are obtained.
