Pulcherriminic acid is a cyclic dipeptide antimicrobial agent with high affinity for Fe³⁺, found mainly inBacillusand yeast. Pulcherriminic acid chelates iron ions through a non-enzymatic reaction to form the extracellular red pigment pulcherrimin, which competes for iron nutrition and thus achieves an antibacterial effect. Pulcherriminic acid has great applications in food, agriculture and medical industries^[1][2].

Pulcherriminic acid can inhibit the formation ofBacillus subtilisbiofilm^[2].
Pulcherriminic acid can form insoluble red pigment pulcherrimin in the presence of Fe³⁺to compete for iron nutrients, thereby inhibiting the growth ofMetschnikowia yeasts^[3].
