Abstract: Methods of treating or reducing biofilms, treating a biofilm-related disorder, and preventing biofilm formation using D-amino acids are described.

Abstract: A method of treating, reducing, or inhibiting biofilm formation by bacteria, the method comprising: contacting an article with a composition comprising an effective amount of a D-amino acid, said composition being essentially free of the corresponding L-amino acid, thereby treating, reducing or inhibiting formation of the biofilm, wherein the D-amino acid is selected from the group consisting of D-alanine, D-cysteine, D-aspartic acid, D-glutamic acid, D-histidine, D-isoleucine, D-lysine, D-leucine, D-asparagine, D-proline, D-glutamine, D-arginine, D-serine, D-threonine, D-valine, D-tryptophan, D-tyrosine, and a combination thereof.

Abstract: The invention features a novel method for identifying compounds capable of affecting a microbial biological activity, such as biofilm formation, development and dissolution. The method includes: (a) obtaining supernatant from a closed culture system that contains at least one type of microorganism; (b) exposing a target organism to the supernatant or an extract thereof; and (c) measuring the level of the biological activity. Compounds identified by this method are provided, as wells as methods for disrupting biofilms and inhibiting or promoting their formation.
