Bioprospecting Heavy‐Metal Rhizospheres for Novel Therapeutics Against High‐Priority Multi‐Drug‐Resistant Pseudomonas aeruginosa and Acinetobacter baumannii: A Case of Toxic to Treatment

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 5, October 2025.
Heavy metal stress induced the secretion of metabolites not secreted by non‐stressed microbiota. Heavy metal‐stressed microbiota secrete metabolites that inhibit XDR pathogens effectively. UPLC LC–MS tentatively identified novel metabolites, Tolyposamine and Gentiatibetine.
