摘要：

The production of siderophores by nine strains (six species) of the genus Trichoderma was investigated. Under conditions of iron deficiency, the culture filtrate of all strains contained coprogen, coprogen B, and ferricrocin. In addition, T. longibrachiatum and T. pseudokoningii produced siderophores of the fusigen type. The yields of siderophores varied according to the strains examined from 270 mg/l (strain HA 34-88) to 2080 mg/l (strain HA 113-84). In extracts of the mycelia of T. longibrachiatum and T. pseudokoningii no siderophores could be detected. From the mycelia of the other strains three siderophores, namely coprogen, ferricrocin and a new coprogen derivative which carried a palmitoyl instead of an acetyl group, were obtained. Palmitoylcoprogen is the first fungal siderophore which is solely found in the cells and is not excreted into the culture broth.
