Abstract

Abstract: Shewanella are known for versatility in their electron accepting capacities, which allow them to couple decomposition of organic matter to reduction of the variety of terminal electron acceptors encountered in the stratified environments they inhabit. Due to their diverse metabolic capabilities, shewanellae play important roles in carbon cycling and have considerable potential for remediation of contaminated environments and use in microbial fuel cells. Systems-level analysis of the model species, S. oneidensis MR-1, and other members of this genus have provided significant insights into the signal transduction proteins, regulators, and metabolic and respiratory subsystems governing the remarkable versatility of the shewanellae.
