[The relationship between the conditions of cultivation and sporification of various Bacillus strains and the results of the evaluation of the sporocidal activity of chemical desinfectants].

The researchers compared the main microbiological characteristics of some Bacillus antracoides strains after their cultivation in different nutrient media. The study found that the growth and sporification rate, R-S dissociation ability, and sensitivity to disinfectants are strain properties and significantly depend on the composition of the nutrient medium.

[A research into the possibility of the application of new peroxosolvate-based compounds as chemical disinfectants].

A newly synthesized peroxosolvate, ammonium sulphate peroxosolvate, can be used in disinfectology and other areas along with other hard forms of hydrogen. Optimal conditions for ammonium sulphate peroxosolvate synthesis were determined by this study. It was established that (NH4)2SO4 .

[The development of peroxosolvate-based composites and the evaluation of their effectiveness against extremely dangerous infective pathogens].

The article contains the results of the test of PFK-M composition bactericidal activity against a range of extremely dangerous infective pathogens. The preparation proved to be highly effective for the disinfection of surfaces, sanitary and technical equipment, linen, dishes, and medical utensils contaminated by plague, cholera, and anthrax pathogens. The study found that the antimicrobial activity of the preparation increased after heating and lowered when the object to be disinfected was contaminated with protein admixtures.

[A research into the possibility of biological control over technophilic microorganisms using KSAP-U, a military device for biological reconnaissance].

The paper is dedicated to the detection of technophilic microorganisms, able to affect fuels, lubricants, and construction materials. The study demonstrated that indicator paper used in KSAP-U, a biological reconnaissance device, was able to detect technophilic test microorganisms in samples of rubber, turbonit, and the water phase of the "fuel-medium" system even when the degree of material affection was minimal. The authors suggest the practical application of these means for the express indication of technophilic microorganisms in technical objects.

[Maintenance of cold chain for the delivery of immunobiological drugs by the indicators of heating and freezing controls].

The paper deals with an objective evaluation of a qualitative storage of immunobiological drugs including all stages of "cold chain". The results of technological research and of designing related with constructing a system of indicators for monitoring the temperature regime to maintain the "cold chain" functioning are presented. The suggested devices are comparatively described.
