Trichoderma strains were screened for siderophore production and the antimicrobial activities of the crude siderophore preparations against various fungi were compared. The siderophores of T. harzianum strains CBS 243.71 and VTT-D-80150 were most promising and were selected for further studies. The siderophores were purified from culture filtrates using gel-filtration and ion exchange chromatography and the antimicrobial activities of the purified siderophores against molds, yeasts and wood rotting fungi were assayed. T. harzianum VTT-D-80150 concentrated culture filtrates as well as the purified siderophore inhibited the growth of the indicator yeasts. T. harzianum CBS 243.71 siderophore inhibited the growth of brown-rot fungi.
