ABSTRACT
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. According to the results of the disinfectological expertise, the preparation was recommended for practical application.

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 . H2O2 stabilized with carboxylic acids did not lose active oxygen when stored in dry atmosphere. The sporocidal activity of the compound against the suspension of B. cereus var. anthracoides 250 was studied. The results demonstrate that thanks to the high decontaminating activity of the solvate its solutions can be used to produce disinfecting preparations.

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.
