Iron (Fe), an essential micro-nutrient for marine organisms, is a necessary element for many biochemical processes such as photosynthesis, respiration, synthesis of DNA and chlorophyll, and reduction of nitrate. However, the iron for life is in water under natural pH conditions in the main form of Fe(OH)3. The concentration of soluble iron is very low in seawater due to its insolubility. While iron is the fourth most abundant transition metal in the Earth's crust, the insolubility of iron(III) [KSp of Fe(OH)3 = 10-39] at physiological pH in aerobic environments limits the availability of this essential nutrient severely. Marine microbes face similar challenges for obtaining iron because they live in the environments with very low iron concentrations. In this paper, we summarize the detection methods of siderophores from marine microbials and their structures.
