Yeast Nitrogen base without Amino acids, without Ammonium sulphate and without Folic Acid Size:100g 0714 g/L L-Phenylalanine 0Folic 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 Folic 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.
