FIELD: chemistry; organic. ^ SUBSTANCE: invention relates to the methods of determination of microorganism permeability index and can be used to control the effectiveness of high-efficiency particulate air filter and personal protective gear in biotechnology, sanitary, medical and applied microbiology while working with microorganisms and its toxins. The method for determination of aerosol filter permeability for microorganisms includes preparation of liquid test specimen, its dispersion in aerosol before filter, selection of aerosol samples before and after filter, determination of the biological marker content in aerosol samples. The test specimen of protein initiating ice formation, ice formation activity detection, which is carried out according to occurrence of samples of nucleation centers is used as a marker. ^ EFFECT: insurance of the safe method for determination of microorganism permeability index. |
