Abstract:

The luxCDABE genes (i.e. full cassette) were inserted into the bacterial strain used in this study, E. coli HB101, using a multi copy plasmid, (pUCD607). A number of experiments were carried out in this thesis to study the potential of using the biosensor, E. coli HB101 (pUCD607), for ecotoxicity testing. Growth and bioluminescence of E. coli HB101 (pUCD607) were characterised and optimised, as well as the stability of this biosensor to a range of environmental parameters. The biosensors were found to be sensitive to a range of pollutants and provided a highly consistent bioluminescence respon

A constitutive <I>lux</I>-marked biosensor, <I>E. coli</I> HB101 pUCD607, was developed as a novel, acute, 'fingerprinting' technique by which individual pollutants, and whole effluents, could be identified and quantified. In this way, the advantages of both chemical analysis and toxicology were encompassed in one technique. An assay technique for obtaining temporal response curves was developed by injecting the biosensor into toxic samples, and then measuring luminescence continuously for 5 minutes. An algorithm was formulated, and implemented as a simple computer program, by which 'unknown'
