The results of studies of the influence of nanocarboxylates (citrates) of microelements on Rhizobium radiobacter 204 growth-regulating activities are presented. It was found that increasing bacteria growth-regulating activity is achieved by the content of citrates of Zinc (Zn), Copper (Cu), Manganese (Mn), Iron (Fe) and Molybdenum (Mo) in culture medium in complex. It was shown that the use of nanocarboxylates of microelements while cultivating the investigated strain contributes to the increase of bacterial cells titre in a liquid culture medium by 1 billion/cm3. It was revealed that the cultivation of R. radiobacter 204 under the action of citrates of microelements helps extent the exponential growth phase of these bacteria by 12 hours. According to the research results an optimized liquid culture medium was proposed for bacteria culturing.
