Growth curves of E. faecalis (blue) and E. faecium (green) with DCA, CDCA and CA at 0%, 0.01%, 0.025%, 0.038% and 0.05% bile acid concentration. The OD₆₀₀ was measured every half hour for 5.5 h and after 24 h for E. faecalis and every hour for 12 h and after 24 h for E. faecium. The OD₆₀₀ on the Y-axis is shown in a logarithmic scale
