| Description | Pulcherriminic acid, a cyclic dipeptide antimicrobial compound predominantly found in Bacillus and yeast, exhibits a strong affinity for Fe3+. It chelates iron ions via a non-enzymatic reaction, forming the extracellular red pigment pulcherrimin. This pigment competes for iron nutrition, thereby exerting an antibacterial effect. Pulcherriminic acid holds significant potential for applications in the food, agriculture, and medical industries [1] [2]. |
