DIFFERENTIAL REINFORCED CLOSTRIDIAL BROTH BASE (ISO 6461-1:1986)

Differential Reinforced Clostridial Agar was originally described by Hirsch and Grinstead to initiate the growth from small inoculum and get a higher Clostridial count. Later, Barnes and Ingram used the medium to develop vegetative cells in assays of Clostridium perfringens. This medium is developed for the isolation of sulphite-reducing Clostridia from food and for their enumeration in water by multiple tube method. Differential Reinforced Clostridial Broth is used to determine the count of sulphite reducing bacteria by MPN technique.
