Application Notes

Fulvic acid is a fungal metabolite isolated from three Penicillium species by Raistrick and co-workers in 1935. Identification was based on the highly characteristic green complex formed with ferric ions. Fulvic acid is related to the siderophores, citromycetin and other 2,3-dihydrobenzoates. The literature of fulvic acid is frequently confused with a humic acid component bearing the same name. The biological activity of this fungal metabolite is not extensively characterised but its affinity to ferric ions suggests it complexes metal ions.
