A method for assessment of integral biological toxicity of carbon-based nanomaterials (CBN) using a bacterial luminescent biosensor was developed, which accounted for the properties of the objects under study. The proposed approach includes a special procedure for the preparation of the analyzed CBN samples aimed at obtaining highly dispersed suspensions,(More)
Effect of cations K+, Na+, Mg2+, and Ca2+ and anions Cl−, SO 4 2− , HCO 3 − , and CO 3 2− on the luminescence intensity of the marine luminescent bacterium Photobacterium phorphoreum (Microbiosensor B-17 677f) and the recombinant strain Escherichia coli with cloned lux operon of P. leiognathi (Ecolum-9). It is found that small concentrations of chlorides(More)
We have developed methods of biotesting mineral waters involving use of natural or recombinant luminescent strains with elimination of the effect of degree of mineralization and pH. To overcome the adverse effect of high salt concentrations, disguising the action of chemical pollutants, a special method of mineral water sample preparation is proposed. In(More)
Mineral waters have been ascertained to exert a pronounced inhibiting effect, that is in proportion in their mineralization and pH values, on the fluorescence of microbial luminescent biosensors. To prevent such adverse reactions masking the effects of chemical pollutants, the authors propose an adjusted procedure for preparing the samples of mineral waters(More)
