Fig. 4From: Proliferation of Bifidobacterium L80 under different proportions of milk protein hydrolysateThe content of H2O2 in the metabolites of Bifidobacterium L80 fermentation broth of with 1:9 proportion of macromolecules and small molecule peptides in MPH cultured for 24 h. In the figure, MPH refers to the sample group with 1:9 proportion of macromolecules and small molecule peptides in MPH addition to MRS medium; Control refers to the control group with the milk protein addition to MRS medium; Blank refers to the blank group with the basic MRS medium. a−b Different alphabets indicate significant differences between sample group, control group and blank group within a row (P < 0.05)Back to article page
