Dynamics of interacting of association spore-former soil microorganisms with Fe (ІІІ)

Abstract

Goal. Investigate the dynamics of the interaction of the association of spore-forming soil microorganisms with Fe (III) compounds. Methods. Microbiological, potentiometric, colorimetric methods and gas chromatography were applied. Results The dynamics of the interaction of the association of spore-forming soil microorganisms with Fe (III) compounds was investigated. It has been established that the natural microbial group maintains the stability of the function of introducing Fe (III) compounds. It was found that the efficiency of reduction of Fe (III) in 74 years was 65%, and precipitation efficiency - 35%. Conclusions The ability of an association to interact with Fe compounds indicates its significant role in the biogeochemical cycles of the transformation of Fe in the genus. The assessment of the effectiveness of the interaction of the natural soil association with Fe compounds creates the basis for the development of effective biotechnologies for purifying water from Fe, as well as the removal of its compounds from depleted deposits.
