Evaluation of bactericidal and antioxidant properties of functionalized calix[4]resorcinols and of rhodium complexes based on them
The results of a comparative assessment of bactericidal and antioxidant properties for a number of functionalized calix[4]resorcines and of rhodium complexes are presented on the example of chemical and biological modeling of oil biodegradation and oxidation Fe2+ → Fe3+ in the presence of sulfate-reducing bacteria of the genus Desulfobacter. It was found that the ability to reduce or enhance the biodegradation of oil or to accelerate or slow down the oxidation processes Fe2+ → Fe3+ depends on the concentration of compounds, the type of functional groups in their composition and on their structural characteristic. The enhancement of the bactericidal and antioxidant activity for the complexes is explained by the double effect on the microbial cell in connection with the antibacterial properties of rhodium ions. Recommendations are given on the use of compounds as bactericides to reduce the biodegradation of oil and inhibitors of biocorrosion of oilfield equipment, or as intensifiers of the growth of sulfate-reducing bacteria for the processing of oil waste.
