Yeast Nitrogen base without Amino acids, without Ammonium sulphate and without Nicotinic acid Size:100g Solubility in water at 3Nicotinic acid 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 nicotinic acid or to replace this vitamin. 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.
