Iron and molybdenum caused the highest increase of biomass growth whereas the effect of other microelements was less. While zinc in certain concentrations was introduced into the culture medium the biomass growth was significantly decreased. It was established that the sterilization of medium with the microelements vanadium, germanium, copper, which were previously added to it, significantly decreased their stimulating effect on the growth of bacterial biomass. At the same time, the high temperature treatment positively influenced on the activity of chelates of molybdenum and iron. Using the culture medium, which contained the mixture of cobalt and iron, was more favorable for the growth of nodule bacteria. In this case the highest indexes of the growth of bacteria biomass were noted. Mixture of iron and molybdenum as well as mixture of molybdenum and cobalt were less effective. In this case the sterilization of medium did not influence on the activity of the chelate complexes. The application of the ternary mixture of molybdenum, cobalt and iron had the least positive impact on the biomass growth among the studied mixtures. It was shown that the fulvic acid as compared to other chelators (carbonic acid and humic acid) was the least effective decreasing the rate of the growth of cell biomass by about half. The most effective chelators for microelements increasing the bacteria biomass growth are natural humic acids, therefore, they can be used as biologically active substances to improve the growth of microorganisms.
