Methods of researches - For carrying out of SIP were used the generally accepted biochemical and microbiological methods, and also methods of carrying out of green-house experiments and statistical treatment of results. The objects of researches are the bacterium Enterobacter nimipressuralis 32-3, Phosphoenterin, sorghum (Sudanese grass of sort of Fioleta), lettuce (Odessa kucheryavuy), wheat (var. Fantasiya Odesskaya), soil of chernozem southern. The results. It was established the ability of culture of Enterobacter nimipressuralis 32-3 and Phosphoenterin to microbiological renewal of Cr (VI) under laboratory experiments. It was shown that the speed of renewal of Cr (VI) depends on the phase of development of culture and temperature factor: is the highest activity was marked in a young culture at 28?С. The positive affecting of Phosphoenterin on the activity of renewal of Cr (VI) in water under conditions of non-sterile laboratory experiments was revealed. The influence of the temperature factor and dynamic terms of cultivation on activity of this process was marked. It was determinate the influence of bacterization of seed on plants resistance (sorghum, winter wheat) to stress influence of HM: on the indexes of root index, indexes of repressed of growing and tolerance. It was shown that the inoculation promotes a height, above-ground mass, area of leaves of plants and maintenance in them of photosynthesis pigments (chlorophylls) at the different levels of contamination of soil HM (Pb, Cr, Cu) under green-house experiments. It was revealed the positive influence of inoculation on the quantity of CFU of the basic ecological-trophycal groups of microorganisms in the rhizosphere of sorghum. It was established that the inoculation reduces maintenance of mobile forms HM in rizosphere soil at the high levels of contamination (10 MPC and 20 MPC). It was revealed under green-house experiments the positive influence of mycorization on the productivity (above-ground mass) of soybean of var. Annushka on the background 5 MPC of VM: dry mass of a 1 plant increased in 3 times as compared to control. Influences are not exposed to VAM on activity of nodulation of soybean plants. Under green-house experiments it was shown the positive influence of inoculation on a quantity CFU of cellulose destroyed microorganisms and bacteria, utilizing the organic compounds of nitrogen and phosphorus, at contamination of soil HM: on a background 20 MPC more than in 2 times in comparison with control. The phosphataze activity of soil and intensity of extraction of CO2 increased in the rhizosphere of sorghum on a background 10 and 20 MPC of HM: on 25-30% and 30-45% accordingly, as compared to control. On the base of the got results were working out the recommendations, in which expedience of the using of Phosphoenterin for growing plants on soils, which contaminated by HM.
