Abstract
Chromium (VI) (Cr(VI)) contamination of soil and groundwater is considered a major environmental concern. Bioreduction of Cr(VI) to chromium (III) (Cr(III)) can be considered an effective technology in remediating Cr(VI) contaminated sites. Among the Cr(VI) reducing bacteria,
Shewanella oneidensis MR-1 (MR-1) is relatively effective. Reduction of Cr(VI) by MR-1 is defined by the dual-enzyme kinetic model. Existing models are not able to simulate bioreduction of Cr(VI) by employing the dual-enzyme kinetic model. The objective of this paper is to present a finite element model capable of simulating bioreduction of Cr(VI) by employing the dual-enzyme kinetic model and compare its prediction with experimental results. The model developed is accurate and can provide oscillation-free results for Peclet number

and Courant number
