Among soil anaerobes,\n                    <jats:italic>Geobacter<\/jats:italic>\n                    species occupy a distinctive ecological anoxic niche in which they form syntrophy relationship with partner cells to exchange electrons for anaerobic carbon mineralization, methane production, nitrate reduction, sulfur and Fe(III) reduction. Here, we review how\n                    <jats:italic>Geobacter<\/jats:italic>\n                    -based syntrophy contributes to C\/N\/S\/Fe cycling in anoxic soils.
