Hydrolysis is not completed until all the nitrogen in the casein is converted to amino acids or other compounds of relative chemical simplicity

has been omitted to test the ability of yeast cells to assimilate different nitrogen sources like Potassium Nitrate

Yeast Nitrogen base without Amino acids and without Biotin Size:100g Cells are grown 1-2 daysBiotin is omitted from this formulation of Yeast Nitrogen base w o Amino acids to provide the researcher the possibility to grow yeast cells in the absence of biotin or to replace this vitamin.
