Description
Litmus Milk is a maintenance and differential medium for studying bacterial metabolism in milk.
Litmus functions as both a pH and oxidation-reduction indicator. The medium demonstrates acid production, gas or stormy fermentation, alkaline reactions, casein coagulation, peptonisation and litmus reduction.
Pure cultures are inoculated into tubes and incubated at 35 ± 2°C for up to fourteen days, with reactions recorded at intervals. The PDF identifies particular value in differentiating Clostridium species and maintaining lactic acid bacteria.
