Escherichia coli K12 TGI strain was used as a recipient for transformation. At studying of SOS-system activity the recombinant bioluminescent strain of Escherichia coli recA lux containing plasmid-borne fusions of the recA promoter-operator region to the Photorhabdus luminescens ZM 1 lux genes (GosNlIgenetika, Russia) was used. Increase of their luminescence in the presence of DNA damage factors [Rosen et al., 2000], were shown previously. Investigation of the luminescent response of this strain to UV radiation allows quantitatively estimate in a real time a SOS-system induction.

Bacteria which are almost always sensitive to the sulphonamides include Strep, pneumoniae, /3-haemolytic streptococci, Escherichia coli and Proteus mirabilis those almost always resistant include Enterococcus faecalis, Ps. aeruginosa, indole-positive Proteus and Klebsiella whereas bacteria showing a marked variation in response include Staph, aureus, gonococci, El. influenzae and hospital strains of E. coli and Pr. mirabilis.

Exceptionally, in Escherichia coli acireductone dioxygenase (enediol dioxygenase) carries out two enzymatic activities that are responsible for the salvage of methionine, but are encoded by the same gene. Whereas one enzyme is dependent on Fe and produces the ketoacid and formate (Figure 3.34a), the other that is nickel-dependent produces the carboxylic acid, formate, and CO (Figure 3.34b) (Dai et al. 1999).

Aniline transformed the Balb/3T3 mouse cell line at doses of 0.8 to 100 /dose-response effect), but not the Syrian hamster embryo cells (Dunkel et al. 1981). Results were negative in DNA damage assays in Escherichia coli (Mamber et al. 1983) and Bacillus subtilis (McCarroll et al. 1981). 

Mutagenic responses were produced in Escherichia coli and certain strains of Salmonella typhimurium bacteria by 2,3,7,8-TCDD, but not by octa-CDD (Vos 1978). Further, chromosomal aberrations were induced in at least one species of higher plant and mammal (Ramel 1978). It must be concluded at this time that 2,3,7,8-TCDD is mutagenic or has mutagenic potential.

The concept of recombinant DNA technology is based on the premise that a gene sentence may be taken from an animal or human gene responsible for the production of a particular protein and inserted into the DNA of Escherichia coli, a single-cell bacterium. The bacterial cells then divide very rapidly, making billions of copies of themselves, including a rephea of the gene that has been inserted.
