Principle and Interpretation :
Yeast Nitrogen Base (YNB) w/ Ammonium Sulphate, w/o Vitamins is used for the growth of all strains of Saccharomyces cerevisiae. This yeast strain is called budding yeast and is extensively studied microorganism in molecular and cell biology.
Yeast Nitrogen Base (YNB) w/ Ammonium Sulphate, w/o Vitamins is developed according to the formulae of Wickerham (1, 2) which supplies the required nutritional elements for budding yeast cells. This media is used for the classification of yeast strains based on the carbon and nitrogen requirements and it contains all the essential inorganic salts which are required for the propagation of yeast cells. Furthermore, this media does not contain the amino acids namely, histidine, methionine, leucine, lysine and tryptophan.
Quality Control :
Appearance of Powder : White to off-white, homogeneous, free flowing powder
