Abstract
Abstract A multi-differential agar culture medium which has the capability to differentiate between a large variety of closely related bacterial species, comprising tomato juice, peptonized milk, yeats extract, glucose, calcium pantothenate, a pH lowering agent, a non-diffusible buffering agent, metals and minerals, a wetting agent and stimulator of growth of lactic acid bacteria, an acid-base color indicator, a yeast suppressing agent, and agar.
