Abstract:Release of pollutants has resulted in environmental contamination. Many methods have been applied to remove xenobiotic compounds, and bioremediation was considered as a safer, more efficient and less expensive alternative to treat these pollutants. Although many environmental pollutants are found to be degraded by microorganisms, in some cases, the catabolic potential alone was inadequate, combining with other properties such as chemotaxis to enhance bioremediation has been considered. Bacterial chemotaxis,...
