Abstract: Hexavalent chromium [Cr(VI)] contamination of soil and groundwater is a major concern for some industrial sites as well as many United States Department of Energy sites. Bioreduction of Cr(VI) to less toxic and less mobile Cr(III) has received much attention as a viable method of remediation. However, bioreduction of Cr(VI) also produces soluble organo–Cr(III) complexes and little is known about the fate of these complexes in the environment. Cr(VI) was reduced abiotically in the presence of cellular organic compounds (malate, cysteine, and serine) and biotically in the presence of two test organisms (
