[The effect of nitrofurans on the membrane apparatus of coccal bacteria]. / Deistvie nitrofuranov na membrannyi apparat bakterii kokkovoi gruppy.

Secondary membrane effects on the membrane apparatus of coccus bacteria were being studied. Cultivation of Micrococcus lysodeikticus and Staphylococcus aureus cells on subbacteriostatic concentrations of nitrofurans results in a lower biosynthesis of many membrane proteins, as well as in inhibiting the activity of respiratory enzymes, i. e. the specific concentration of cytochromes and specific activity of NADH-, malate-, lactate oxidases and some reductases drop. Some cytological changes were revealed, when cells were grown on solafur, furazolidone, and furacriline.
