A model of oxygen intake by aerobic bio-objects in liquid incubating media was applied to investigate the influence air-media interface area on accuracy of measuring the oxygen intake and error value. It was shown that intrusion of air oxygen increases the relative error to 24% in open polarographic cells and to 13% in cells with a reduced interface area.(More)
Quaternary ammonium, pyridinium, and morpholinium tetrachloroferrates were prepared. The structures of the salts were confirmed using IR and visible spectroscopy. The antimicrobial activity of the synthesized compounds against several strains of Gram-positive and Gram-negative microorganisms and yeast-like fungi was studied.
