Fig 2. Disruptive effect of MMP1 on E. faecalis biofilms.

Absorption of CV stain at 635 nm (OD₆₃₅) of MMP1-treated biofilms of FA2-2 and V583 strains over seven days. Experiments with BHI media and protein buffer were used as controls. For disruption experiments, biofilms were first grown in BHI media without MMP1 for desired duration, followed by MMP1 treatment. Typical images of wells in microtiter plates are given at the top of each panel. * indicates p-value: *<0.01, **<0.01, and ***<0.001; ns indicates that the effect is not significant. Error bars on the data points represent the standard deviations of 3 technical repeats.
