Yeasts which have grown on a rich medium like Yeast Agar may carry a reserve of nitrogen in the form of protein

Yeast Nitrogen base without Amino acids, without Ammonium sulphate and without Zinc Size:100g 5 g/L L-Proline 0Zinc sulphate, ZnSO4. 7H20 is omitted from this formulation of Yeast Nitrogen base without Amino acids to provide the researcher the possibility to grow yeast cells in the absence of Zinc or to replace this element. Ammonium sulphate, as a source of Nitrogen, has been omitted to test the ability of yeast cells to assimilate different nitrogen sources like Potassium nitrate.
