BRILLIANT GREEN BILE AGAR (BRILLIANT GREEN LACTOSE BILE AGAR)

Brilliant Green Bile Agar was originally formulated by Nobel and Ponney for enumeration of coliform bacteria from materials of sanitary importance. Subsequently APHA approved the medium for the estimation of coliforms in test samples of various materials
It is recommended that the medium be prepared just prior to use and if the medium has to be stored, it should be kept in dark. Brilliant Green Bile Agar medium is sensitive to light, particularly direct sunlight. Direct exposure may exhibit a decrease in the productivity of the medium and also the colour of the medium may change from deep blue to purple or red.
