FN ISI Export Format VR 1.0 FN ISI Export Format VR 1.0 PT J TI Role of Geobacter sulfurreducens Outer Surface c-Type Cytochromes in Reduction of Soil Humic Acid and Anthraquinone-2,6-Disulfonate AU Voordeckers, JW Kim, BC Izallalen, M Lovley, DR SO APPLIED AND ENVIRONMENTAL MICROBIOLOGY VL 76 IS 7 BP 2371 EP 2375 PY 2010 TC 0 AB Deleting individual genes for outer surface c-type cytochromes in Geobacter sulfurreducens partially inhibited the reduction of humic substances and anthraquinone-2,6,-disulfonate. Complete inhibition was obtained only when five of these genes were simultaneously deleted, suggesting that diverse outer surface cytochromes can contribute to the reduction of humic substances and other extracellular quinones.
