 Bacterial biofilms are a major cause of infection and antibiotic resistance. Elagic acid, EA, a naturally occurring polyphenol, has been found to have anti-biofilm properties. Recent research suggests that EA works by disrupting the redox balance of the bacterium, which is controlled by an enzyme called WRBA. By disturbing this balance, EA can prevent or reduce the formation of biofilms, making it a promising candidate for developing novel antimicrobial agents.
