The described microbiotesting technique provides the recording of pH changes, redox potential, electrical conductivity, optical density, light scattering and luminescence intensities, and other parameters of samples with viable test microorganisms incubated in a liquid nutrient medium in the presence and absence of the tested factors. The results of using this system for the analysis of pro- and antibiotic activity of various oil products, as well as weak electromagnetic fields of the megahertz range, are presented. It has been shown that the proposed technique, compared to the standard methods, yields more detailed and objective information and is less time- and labor-consuming. |
