Medvedev P.V., Stepanov А.S., Fedotov V.А. EVALUATION OF CONTAMINATION LEVELS FOR THE WHEAT GRAINS FROM DIFFERENT NATURAL AND GEOGRAPHICAL ZONES OF ORENBURG OBLAST BY SPORES OF THE ROPE PATHOGENSThe paper made evaluation of contamination levels for the wheat grains from different natural and geographical zones of Orenburg Oblast by spores of the rope pathogens through the method of vacuum membrane filtration with the use of nutritious cardboard substrates. The paper revealed wheat contamination level functions of different zones by bacteria Bacillus subtilis and Bacillus Mesentericus; conclusions were made of correlations between grain contamination levels and soil and climatic conditions.Key words: potato bacillus, vacuum membrane filtration, spring wheat, zoning areas.
