PaprE-gfp expression of floating biofilms grown in MSgg medium (A) and the proteolytic activity of harvested floating biofilm spent media (B). (A) PaprE-gfp expression of floating biofilms grown in MSgg media was evaluated by measuring fluorescence. Measurements were performed every half an hour (only every fifth measured data point is shown for clarity). Averages and SEM (standard error of means) of four biological replicates are shown. (B) The proteolytic activity of floating biofilm spent media grown in MSgg media at different time points. Averages and SEM of three biological replicates are shown. A Mann–Whitney U-test was performed to determine statistical significance of discussed differences (∗p < 0.05).
