Zusammenfassung: | 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 from 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. |
