The ectomycorrhizal fungus Cenococcum geophilum was grown in low-iron medium and the excreted siderophores were extracted, purified and analyzed by HPLC. The principal hydroxamate siderophore produced, was identified as ferricrocin as confirmed by analytical HPLC, FAB-mass spectrometry and 1H- and 13C-NMR spectra. Although the occurrence of ferricrocin has been shown earlier to occur in the ericoid mycorrhizal fungi, this is the first report of ferricrocin in a true ectomycorrhizal fungus which is taxonomically related to the ascomycetes.

:外生菌根真菌Cenococcum geophilum在低铁培养基中生长,提取的铁载体被提取,纯化并通过HPLC分析。产生的主要异羟肟酸酯铁载体经分析HPLC,FAB质谱,1H和13C-NMR光谱确认为铁三茂铁。尽管铁蛋白的发生早已显示在类固醇菌根真菌中,但这是铁锈菌在真正的外生菌根真菌中的第一个报道,该真菌在分类学上与子囊菌有关。
