Pulcherriminic acid as an antibiofilm effector: expanding Bacillus functionality against yeast biofilms.

Pulcherriminic acid produced by Bacillus subtilis is linked to disrupting Candida albicans biofilms by depriving fungi of essential iron.

• Why it matters: Persistent biofilms pose significant challenges in medicine and industry due to their resistance to antibiotics and ability to cause ongoing infections. Understanding natural antibiofilm agents like pulcherriminic acid could offer sustainable solutions.
• What they did: The review discusses the biosynthesis of pulcherriminic acid, its mechanism of iron deprivation to inhibit fungal growth, and methods to enhance its production through metabolic engineering.
• The result: Harnessing pulcherriminic acid may enable new strategies for combating biofilm-related problems across medical, agricultural, and food preservation sectors.
