METALLIC SALTS ACTION ON BACTERIAL BIOLUM INESCENT SYSTEMS OF DIFFERENT COMPLEXITY

Action of metallic salts on the bacterial bioluminescent systems (1 - water-soluble coupled system luciferase - NADH:FMN-oxydoreductase; 2 - immobilized in starch gel coupled system luciferase - NADH:FMN-oxydor eductase; 3 - intact bacteria) has been studied. The action parameters have been calculated. The effects have been shown to depend on nature of cations but not anions. Electronic structure of cations (nature of external orbitals, charge, radii) has been taken into account. Cation s with similar electronic shells nature affect on the row of the biolu minescent systems mentioned above in a similar way. Differences in eff ects have been explained with diffusion rate, cellular shell and respi ration of bacteria.
