(a) In vitro competition experiments between the B. infantis strains EVC001 and NLS in the HMO standards lacto-N-tetraose (LNT), lacto-N-neotetraose (LNnT), 2′-fucosyllactose (2′-FL), or an equal combination of all three (mixed HMO (mHMO)). (b) Percent consumption of individual HMO standards by B. infantis EVC001 and B. infantis NLS during growth on mHMO. Statistical significance of strains in competition was determined by two-way repeated-measures ANOVA with Holm–Sidak multiple comparison adjustment. Significant differences in percent consumption were determined by Student’s t-test.
