Substances of peptide nature have been isolated from low-molecular-weight fraction of extracellular metabolites of Pseudomonas chlororaphis (strains IB 51 and IB 6) and Pseudomonas putida (strain IB 17). These substances possess antifungal activity against a broad range of phytopathogens but lack the properties of siderophores. It has been shown by HPLC, IR, and C-13 NMR spectroscopy that isolated metabolites are glycerol tripeptides with molecular weights in the range 2.8-3.0 kDa.
