Abstract
Nisin activity is usually quantified using agar diffusion methods. The assay sensitivity (increase in zone size/increase in nisin concentration) for nisin was greatly increased by using Lactobacillus sake ATCC 15521 as the indicator organism, rather than Micrococcus luteus ATCC 10420, the previous indicator organism of choice.Keywords
