Abstract

Iron is a required nutrient for all living organisms. The magnetic spirillum, Aquaspirillum magnetotacticum possesses the ability to transform this metal to intracellular magnetite. Presented in this dissertation are studies relating to iron chelation and transport mechanisms used by this Gram negative bacterium. In addition, physiological roles of iron, specifically in respiration and the cellular localization of iron-containing respiratory components are also addressed.
