General Information: Isolated from shallow marine deposits (coastal shelf mud) of the Amazon River delta off of the coast of Brazil. Iron-reducing bacterium. This genus includes species that inhabit a wide range of environments and are capable of utilizing a wide variety of electron acceptors during anaerobic respiration including some insoluble metal oxides while using very few carbon sources such as lactate or acetate. This group of organisms have been studied extensively for their electron transport systems. Shewanella amazonensis is capable of anaerobically reducing iron, manganese, and sulfur compounds and may be important to the cycling of these compounds in the environment.
