对木霉属9株（6种）产铁载体进行了研究。在缺铁条件下，所有菌株的培养滤液均含有coprogen、coprob和铁蛋白。此外，长腕藤和假柯宁藤产生了融合型的铁载体。不同菌株的铁载体产量从270 mg/l（菌株HA 34-88）到2080 mg/l（菌株HA 113-84）不等。在长尾藤和假孔氏藤菌丝体提取物中均未检测到铁载体。从其他菌株的菌丝体中获得了3个铁载体，即铜原、铁蛋白和一个新的含棕榈酰而不是乙酰基的铜原衍生物。棕榈酰coprogen是真菌中第一个仅存在于细胞内而不排泄到培养液中的铁载体。
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.
