Effect of carolacton concentration on the membrane damage of S. mutans biofilms. Biofilms were grown for 24 h under anaerobic conditions and stained using the LIVE/DEAD BacLight Bacterial Viability kit. Green and red fluorescence was determined, and biofilm damage was calculated as reduction of the fluorescence ratio green/red compared to untreated controls. Each data point is the average of triplicate samples. Standard deviations are given for data points determined in at least three independent experiments.
