Abstract Since ericoid mycorrhizae become dominant in heathland plant communities on acid soils, we assessed the effect of pH on the hydroxamate siderophore production by a typical ericoid mycorrhizal fungus under pure culture conditions. In addition, we determined whether the supplementation of the nutrient medium with L-ornithine or L-proline as precursors for hydroxamate siderophores would enhance their biosynthesis. The results indicate that the hydroxamate siderophore production by Hymenoscyphus ericae has its optimum at pH 4.5 (between 3.5 and 5.5). L-ornithine rather than L-proline appears to favour the biosynthesis of hydroxamate siderophores.
