Yeast Nitrogen base without Amino acids, without Ammonium sulphate and without Biotin Size:100g 20 Heavy Metals <5 ppmBiotin 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 biotin 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.
