[On the effect of particulate airborne substances on various micro-organisms (author's transl)].
Experimental studies on the reaction of micro-organisms on fine-dust filters (type C) and high-efficiency particulate air filters (type R and S) have shown no evidence of a growth of microorganisms. Therefore efforts were aimed at detecting antimicrobial factors which were supposed to exist in the precipitated acidic continental aerosol. With this in mind, air filters from different locations and with service times were extracted in water and the extract was tested for its antimicrobial effects. Die-off rates are used to demonstrate the influence of such extracts with varying concentrations of substances and pH values on bacteria.
