Abstract

Bacterial respiratory Fe(III) reduction makes a considerable impact in a range of micro-oxic and anoxic environments. We have identified a number of c-type cytochromes in Shewanella frigidimarine that are either specifically expressed or significantly up- regulated in cells cultured with Fe(III) as the sole terminal electron acceptor present. We now aim to (i) study in detail the molecular basis for Fe(III)-responsive gene transcription in this bacterium, (ii) assess the roles of the different hemoproteins in Fe(III) respiration by construction of mutant strains and subsequent characterisation using continuous culture; and (iii) investigate a potential role for outer membrane beta-barrel proteins in respiratory Fe(III) reduction.
