Yeast Nitrogen base without Amino acids, without Ammonium sulphate and without Manganese Size:1000g Amongst all amino acids especially

Amongst all amino acids especially Tryptophan is present in high concentrations

glycerol is not fermented to acetic acid

MAL Indicator Medium is a fermentation-indicator medium used to distinguish strains that ferment maltose or not

Methionine and Tryptophan concentrations has been reduced to 10% of their original concentration as present in Yeast Nitrogen Base

Yeast Nitrogen base without Amino acids, without Ammonium sulphate and without Manganese Size:1000g Amongst all amino acids especiallyManganese sulphate, MnSO4. H20 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 Manganese 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.
