FIG. 2.
High-performance anion-exchange chromatography with pulsed amperometric detection (HPAEC-PAD) analysis of supernatants of B. animalis subsp. lactis BB-12 cultures propagated on XOS. Concentrations of different XOS species in the supernatants of BB-12 cultures grown on XOS collected from initially grown cells and stationary cells, respectively, are designated. The results represent mean values and standard errors for results from three biological replicates.
