The Dehesh Lab recently published a study in Nature Communications identifying MEcPP, a conserved metabolite found in Gram-negative and some Gram-positive bacteria, as well as plastid-bearing organisms, as a key inhibitor of Escherichia coli biofilm formation.

Biofilms, microbial communities encased in an extracellular matrix, drive antibiotic resistance, persistent infections, and equipment fouling, posing significant medical and industrial challenges. The discovery of MEcPP’s biofilm-disrupting properties highlights its potential as a novel tool for addressing biofilm-associated issues.

This work reveals new insights into conserved metabolic pathways and their influence on microbial behavior, offering a foundation for strategies to mitigate biofilm-related challenges in healthcare, agriculture, and industry.
