*2.3.6 Amino acids*

d-Amino acids have been shown to inhibit biofilm formation in *B. subtilis*, via activating the release of amyloid fibers [122]. Such inhibitory effect was reversed by their cognate l-amino acids [123]. Furthermore, d-amino acids were shown to have antibiofilm activity in case of *P. aeruginosa* and *S. aureus* [122].
