Abstract EN

In this study, a biosensor is designed to remove mercury as a toxic metal contaminant from the soil.

The rhamnolipid biosurfactant was used to extract the mercury sorbed to soil to the aqueous phase.

An immobilized bioluminescent bacterium (Escherichia coli MC106) with pmerRBPmerlux plasmid is assisted for mercury detection.

A significant decrease in luminescence level was observed in a biosensor system containing contaminated soil sample extract.

The concentrations of extracting mercury are well correlated with the mercury toxicity data obtained from experimental biosensor systems according to the RBL value.

The optimum aeration rate of 20 ml/min was obtained for the biosensor systems.

The advantage of such a biosensor is the in situ quantification of mercury as a heavy metal contaminant in soils.

Therefore, this system could be proposed as a good biosensor-based alternative for future detection of heavy toxic metals in soils.
