ANDRADE PEPTONE WATER (VEG.)

These media contain Veg peptone or/and Veg extract No.1 of vegetable source in place of Peptic digest of animal tissue and Meat extract which makes the medium free of BSE/TSE risks associated with animal based peptone. Andrade Veg Peptone Water is used for studying the various carbohydrate fermentation patterns of different organisms. The Andrade indicator changes colour from yellow to pink as the pH decreases. The medium is pink when hot but becomes straw coloured on cooling. Test carbohydrate solutions should be sterilized separately and aseptically added to sterile Andrade Veg Peptone Water. The biochemical identification of organisms capable of growing in this medium is made by various sugar fermentation results. Use fresh cultures of organisms only which have been presumptively identified by gram staining and colony morphology. For final identification further biochemical tests are required.
