Abstract

A method and medium for selective growth of Propionibacterium from mixed culture samples is disclosed. The medium comprises a lactic acid source as its primary energy or nutrient source and in combination therewith a small but effective amount of a heavy metal salt to which Propionibacterium is resistant, selected from a group of water-soluble cadmium and arsenic salts.
