Jl. Erbe et al., CYANOBACTERIA CARRYING AN SMT-LUX TRANSCRIPTIONAL FUSION AS BIOSENSORS FOR THE DETECTION OF HEAVY-METAL CATIONS, Journal of industrial microbiology, 17(2), 1996, pp. 80-83
The metal-responsive smt operator/promoter region of Synechococcus PCC
7942 was fused to the luxCDABE genes of Vibrio fischeri. Plasmid DNA (
pJLE23) carrying this fusion conferred metal ion-inducible luminescenc
e to transformed cyanobacteria. Synechococcus PCC7942 (pJLE23) was sen
sitive to ZnCl2 concentrations within a range of 0.5-4 mu M as demonst
rated by induction of luminescence. Trace levels of CuSO4 and CdCl2 we
re also detected.
