Lactose Sulfite Broth prepared according to the formulation specified in ISO 7937 is a medium for confirmations of clostridium perfringens and sulphite reducing clostrides due to their ability to metabolize lactose by producing gas and H2S. The colour change of the test-tube determines the presence of clostridium perfringens.
After sterilization, add a 1.5% sodium metabisulphite solution and 1% ammonium citrate solution.
