Abstract
The dissimilatory iron-reducing bacterium Geobacter metallireducens was fou nd to require iron at a concentration in excess of 50 muM for continuous cu ltivation on nitrate. Growth yield (similar to3-fold), cytochrome c content (similar to7-fold), and nitrate (similar to4.5-fold) and nitrite (similar to 70-fold) reductase activities were all increased significantly when the growth medium was amended with 500 muM iron.
