Experimental Study of Polydispersive Bacterial Aerosols. Report I. The Theory of the Method for Determining the Survival of Microorganisms in a Polydispersive Bacterial Aerosol

摘要

Conclusions: A formula has been proposed for calculating the survival of microbes in a polydisperse bacterial aerosol, making it possible to exclude the influence of the physical process in the aerosol on the survival index. It has been established that the appearance of a considerable number of nonmicrobial particles in the aerosol can lead to the obtaining of a mistaken result. It is shown theoretically that the upper limit of applicability of the method is an excessive number of microbes in the particle, making a quantitative calculation of them inaccessible, and the lower limit -- the critical radius of the system, depending on the concentration of the initial suspension, or the critical concentration of the initial suspension -- 1.92 . 10 to the 9th power cells/cc.
