Himedia Purple HiVeg Broth Base

Purple HiVeg™ Broth Base

Details

Purple HiVeg™ Broth Base is recommended for the preparation of carbohydrate media used in fermentation studies for the cultural identification of pure cultures of enteric and other microorganisms. Positive reaction is indicated by change in colour of medium to yellow due to fermentation of carbohydrate and bromocresol purple the pH indicator in the medium. Gas produced is entrapped in Durham`s tube. If the carbohydrate is not utilized or fermented, the color of the medium remainsunchanged or becomes more alkaline (darker purple) due to decarboxylation of the amino acids present in the medium. Purple HiVeg™ Broth Base is prepared by using vegetable peptones in place of animal based peptones which make the media free of BSE/TSE risks.
