[Increased efficiency in the disinfection of sewage by lactic acid bacteria]

The antimicrobic properties have been studied in 30 strains of lactobacilli. As a result a strain, the strongest antagonist relative to choleric vibrios and other enteropathogenic microorganisms, is selected. Lactobacilli are found to retain their viability and biological activity in the activated sludge during the whole period of observation (6 months). Biological disinfection of sewage is shown possible to be intensified using the activated sludge inoculated by the culture of the selected lactobacilli strain.
