Abstract
A soil isolate of Rhizobium leguminosarum bv. trifolii was marked with a lux CDABE gene cassette to enable the expression of bioluminescence . The suitability of the bacterium as a soil pollution biosensor was a ssessed using acute and chronic assays. Bacterial bioluminescence resp onded sensitively to the metals studied, The order of sensitivity was found to be Cd > Ni = Zn > Cu for the acute test and Cd > Ni = Zn = Cu for the chronic test. The sensitive response of the biosensor highlig hted its potential for use as an indicator of soil pollution.
