An iron-binding compound was isolated from ethyl acetate extract of culture supernatant fluid of Rhizobium trifolii AR6 and was purified by iron-exchange chromatography. The compound was characterized by UV and IR. It contained 2,3-dihydroxy-benzoic acid and threonine and was accumulated during stationary phase of growth in iron-deficient media. Synthesis of the siderophore was repressed by FeCl3. In iron limited medium the compound promoted growth of R. trifolii strains.
从三叶草根瘤菌AR6培养上清液的乙酸乙酯提取物中分离出一种铁结合化合物，并通过铁交换色谱法进行纯化。该化合物通过紫外和红外光谱进行表征。它含有2,3-二羟基苯甲酸和苏氨酸，并且在缺铁培养基的生长稳定期积累。该铁载体的合成受到FeCl3的抑制。在铁限制培养基中，该化合物促进了三叶草根瘤菌菌株的生长。
