The aim of the research was the isolation from drinking water the pure cultures of iron- and manganese-oxidizing microorganisms with further assessment of their efficacy to remove these contaminants on rapid filters. To assess the effectiveness selected strains were grown on the solid nutrient medium; the suspension was prepared and was treated to zeolite loading. Ten pure cultures of iron- and manganese-oxidizing bacteria were isolated and identified as 6 genuses: Siderocapsa, Leptothrix, Sphaerotillus, Galionella, Metallogenium, Hyphomicrobium. Comparison the efficiency of genuses Leptothrix, Sphaerotillus, Metallogenium has shown that under conditions of these experiments Leptothrix more effectively removed iron and manganese at low concentrations in model solution.
Key words: iron- and manganese-oxidizing microorganisms, rapid filters, zeolite loading.
