Biological Cycling of Trace Metals in the Sea

最近的计算表明， 表层海水中微量金属的含量应该超过所有其他 输入。 为了解决生物循环的问题 微量金属在表层海水中，该项目将扩大 首席研究员对金属吸收的研究 浮游植物研究细菌的金属吸收和作用 细菌在生物源金属化合物的矿化中的作用。 这项研究将包括藻类的动力学研究， 细菌对Fe、Zn、Cu、Ni、Co和Cd的吸收， 确定金属吸收和金属储存化合物，以及 作为金属蛋白质，并量化的机制， 负责从这些化合物中释放金属。

Recent calculations indicate that the recycled biogenic flux of trace metals in surface seawater should overwhelm all other inputs. In order to address the question of the biological cycling of trace metals in surface seawater, this project will expand on the principal investigator's research on metal uptake by phytoplankton to study metal uptake by bacteria and the role of bacteria in the remineralization of biogenic metal compounds. This research will include studies of the kinetics of algal and bacterial uptake of Fe, Zn, Cu, Ni, Co, and Cd, and the identification of metal uptake and metal storage compounds as well as metalloproteins, and the quantification of the mechanisms responsible for the release of the metals from these compounds.
