title: [Method of determining the concentration of the antibiotic nisin].
abstract: To accelerate determination of nizin concentrations by the agar-diffusion method it is suggested that Twin-80 be added to the agar. For making the media composition more simple, agarized phosphate buffer, pH 5.0, or agarized water, pH 7.0, is recommended to be used for the lower layer.
