Studying the disinfectant action of a new drug in experiments with organic load

The new drug is a complex of chemicals consisting of detergent components (anionic surfactants) and active substances with a biocidal effect (aldehydes, alkali). To assess the disinfecting effect, microorganism isolates isolated from the technological premises of enterprises for keeping cattle were used as test cultures, represented by the following types of bacteria (Escherichia coli, Staphylococcus aureus, Streptococcus faecalis, Aspergillus spp, Bacillus subtilis). A sterile protein-fat mixture (organic load) was used to simulate industrial contamination. As a result of laboratory studies, it was found that under conditions simulating pollution at animal keeping enterprises, the new drug has an effective disinfecting effect against both non-spore-forming and spore-forming microorganisms. The presence of a disinfectant effect in the new drug occurred when exposed to a 3 % concentration at a 180-minute exposure against non-spore-forming microorganisms, including fungi (E. coli, S. aureus, S. faecalis, Aspergillus spp). When the drug acted on the spore-forming test microorganism B. subtilis, a sporicidal effect was observed when using a 4 % concentration and 120-minute exposure.
