Rapid Anaerobic Benzene Oxidation with a Variety of Chelated Fe(III) Forms

Appl Environ Microbiol. 1996 Jan;62(1):288-91. doi: 10.1128/aem.62.1.288-291.1996.


Fe(III) chelated to such compounds as EDTA, N-methyliminodiacetic acid, ethanol diglycine, humic acids, and phosphates stimulated benzene oxidation coupled to Fe(III) reduction in anaerobic sediments from a petroleum-contaminated aquifer as effectively as or more effectively than nitrilotriacetic acid did in a previously demonstrated stimulation experiment. These results indicate that many forms of chelated Fe(III) might be applicable to aquifer remediation.
