Yeast Potassium Nitrate Nitrogen Base Size:500g Yeast extract 10 Peptone 20Yeast Potassium Nitrate Nitrogen Base contains Potassium Nitrate as a sole nitrogen source to test nitrogen assimilation. The addition of a carbon source is required. Histidine, Methionine and Tryptophan concentrations has been reduced to 10% of their original concentration as present in Yeast Nitrogen Base. Yeasts which have grown on a rich medium like Yeast Agar may carry a reserve of nitrogen in the form of protein. To avoid errors due to this
