A biotesting procedure that makes it possible to record the changes in the intensities of elastic light scattering, light absorption, and intrinsic photofluorescence of the protein component, as well as the determination of the concentration and structuring coefficients of the genomic component, of the samples with viable unicellular test organisms incubated in a liquid nutrient medium in the presence and absence of various external chemical factors, is described. The results of the analysis of the antibiotic activity of various metal cations with the use of this technique are presented. This technique is much more rapid, objective, and comprehensive for the assessment of the effect on the reproduction rate, metabolic activity, and genome structure of the test organisms from the samples of various products, wastes, etc. than standard visual microbiotesting methods. |
