海洋微生物面临着获得在海洋中生存和繁衍所需的必需金属离子的独特挑战。产生有机配体以络合过渡金属离子是一种既促进特定金属（如铁）的吸收又减轻其他金属离子（如铜）的潜在毒性作用的策略。许多重要的痕量金属离子在海水中被有机配体络合，包括铁、钴、镍、铜、锌和镉，从而定义了这些金属离子在海洋中的形态。在铁的情况下，铁载体已被确定和结构特征。铁载体是由海洋细菌产生的低分子量铁结合配体。虽然已经取得了进展，在原位铁结合配体的身份，很少有化合物已被确定为协调其他痕量金属。破译自然产生的有机配体和它们来自的生物体的化学结构和生产刺激是理解金属形态和生物利用度的基础。海洋配体，强调铁载体，和讨论的重要性和影响的金属结合配体在控制金属形态和循环在世界海洋的当前证据。
Marine microorganisms are presented with unique challenges to obtain essential metal ions required to survive and thrive in the ocean. The production of organic ligands to complex transition metal ions is one strategy to both facilitate uptake of specific metals, such as iron, and to mitigate the potential toxic effects of other metal ions, such as copper. A number of important trace metal ions are complexed by organic ligands in seawater, including iron, cobalt, nickel, copper, zinc, and cadmium, thus defining the speciation of these metal ions in the ocean. In the case of iron, siderophores have been identified and structurally characterized. Siderophores are low molecular weight iron-binding ligands produced by marine bacteria. Although progress has been made toward the identity of in situ iron-binding ligands, few compounds have been identified that coordinate the other trace metals. Deciphering the chemical structures and production stimuli of naturally produced organic ligands and the organisms they come from is fundamental to understanding metal speciation and bioavailability. The current evidence for marine ligands, with an emphasis on siderophores, and discussion of the importance and implications of metal-binding ligands in controlling metal speciation and cycling within the world’s oceans are presented.
