Modeling of 1,2-Dibromoethane Biodegradation in Constant Electric Field

This study proposes a mathematical modeling approach for evaluating the effect of applying permanent electric field on biodegradation 1,2-dibromoethane by bacterial cells Bradyrhizobium japonicum 273. Two models inhibited microbial growth including product inhibition were composed—one using Monod–Yerusalimsky and another one—the Levenspiel kinetic equation. The used to process own experimental data obtained without an ones at application field. experiments carried out optimum anode potential 0.8 V vs. standard hydrogen electrode (SHE). Three initial concentrations substrate tested: 0.05, 0.1, 0.15 g dm−3. takes into account assuming 2-bromoethanol as first product. It was found that positive is enhancement growth, expressed increase in maximum specific rate constant when model applied. main removal electrochemical oxidation, enabling conversion results show leads higher oxidation (with up 60% than control experiments) complete biodegradation. not so sensitive effects inhibition.
