Colistin is a cationic cyclic polypeptide antibiotic belonging to the polymyxin family and targeting bacterial membranes. It is produced by Paenibacillus polymyxa through a Nonribosomal Peptide Synthetase (NRPS) mechanism. In the context of cystic fibrosis (CF), colistin is used for the treatment of lung infections caused by multiresistant Gram-negative bacteria including Pseudomonas aeruginosa. Unfortunately, this molecule is also known for its strong side effects. So far, genetic systems controlling the production of polymyxins were little known. In this study we characterized by High-resolution LC-MS the antimicrobial molecules, including colistins, of a new Paenibacillus. A genomic library of this strain was constructed and screened to ...
