SUMMARY
Conclusions. Conclusions are made about the prospects of further investigation of the influence of the magnetic field on the microorganisms of genera: Leptotrix, Sphaerotillus, Gallionella, Hyphomicrobium. An important direction for further experiments is the study of possible ways of conducting magnetic separation of iron- and manganese-oxidizing bacteria to prevent secondary contamination of drinking water and the formation of scales in pipelines. The use of the magnetic properties of the investigated microorganisms is useful for the development of ways to remove old scales within pipelines.
