C.L.E.D. AGAR W/ ANDRADE INDICATOR (CYSTINE LACTOSE ELECTROLYTE DEFICIENT AGAR) (VEG.)

C.L.E.D. Veg Agar with Andrade Indicator is specially developed using Veg peptone, Veg hydroysate and Veg extract to avoid BSE/TSE risks associated with animal origin peptones. Originally Mackey and Sandys devised C.LE.D. medium with lactose, L-Cystine and BTB for growing urinary pathogens. C.L.E.D. Veg Agar with Andrade Indicator is the modification of this medium and is recommended for urinary bacteriology, supporting the growth of all urinary pathogens and giving good colonial differentiations. Veg peptone, Veg hydrolysate and Veg extract provide essential growth nutrients. Lactose is the fermentable sugar. L-Cystine supports the growth of cystine-dependent coliforms. Bromothymol blue is the pH indicator which turns yellow at acidic pH. Addition of Andrade?s indicator, enhances the appearance of colony and aids in the identification of microorganisms. At different pH values, the colour of the medium varies from the standard medium, which is well documented by Bevis.

for isolation and di?erentiation of microorganisms based on lactose fermentation
