Iron catalyzed reduction of chromate by dissimilatory iron-reducing bacteria.

The toxicity and mobility of chromium can be diminished through its reduction from the hexavalent state to the trivalent form. Here we demonstrate a microbially mediated pathway for chromate reduction. Iron reducing bacteria, ubiquitous organisms within soils and sediments, stimulate chromate reduction by generating ferrous iron--a facile reductant of hexavalent chromium. Subsequent to reduction, Cr(III) then precipitates as a chromium hydroxide.
