Effect of MgSO₄, NaHCO₃, KH₂PO₄, K₂HPO₄ and Ascorbic Acid on Survival of Bifidobacterium bifidum during Freeze-Drying

Abstract:

Effect of MgSO₄, NaHCO₃, KH₂PO₄, K₂HPO₄ and ascorbic acid on the survival of Bifidobacterium bifidum and the number of viable cells of lyophilized powder was studied. Results were as follows: addition of MgSO₄, NaHCO₃, KH₂PO₄, K₂HPO₄ and ascorbic acid into B. bifidum paste could significantly improve the survival rate of B. bifidum and the number of viable cells of lyophilized powder. The optimal concentrations of MgSO₄, NaHCO₃, KH₂PO₄ , K₂HPO₄ and ascorbic acid were 0.20%, 0.60%, 1.80%, 1.40% and 2.20, the survival of B. bifidum was 78.31%, 77.92%, 77.80% ,79.82% and 71.62, respectively.
