BD Dehydrated MediaTryptone to 2xYT Broth BD Diagnostics Xld Agar. This Dehydrated Agar from BD Diagnostics is used for identification and cultivation of enteric gram-negative bacteria especially for milk and milk products. Yeast and molds that grow in the presence of tryptophan a nitrogen source will grow in the absence of tryptophan but will not grow in the presence of other nitrogenous compounds such as urea methanol acroleic acid and acetate. These properties make Tryptone Agar an excellent base for bacterial cultivation when trying to differentiate gram-negative bacteria from those that are pathogenic for humans and animals. In Vitro agars provide a solid base for bacterial growth with a minimum of nutritive supplementation. The agar base used for the preparation of YTA broth can be used for enrichment but in the case of XLD Agar only agar can be used. For plant and dairy products BD Yeast Agar can be used as a base for the cultivation of non-fastidious organisms that can be used in food beverage dairy water and wastewater microbiological testing as well as cosmetics and pharmaceutical industry testing.
