Effect of alternative peptide sequences on biofilm formation. (A) Biofilm biomass of S. mutans and S. aureus, with results combined from three replicate experiments. All peptides were used at 0.1 mg/ml final concentration. Error bars indicate standard error of the mean. **p < 0.01, ***p < 0.001, ****p < 0.0001. (B) Amino acid sequences of synthetic peptides with color-coded amino acid properties.
