Anti-oxidant defense of the cell Desulfovibrio desulfuricans B-1388.
The extracts of Desulfovibrio desulfuricans B-1388 cells, grown in anaerobic condition, display the superoxide dismutase activity. The maximum value of level activity (1.02 E/min/mg) is observed in the stationary phase of growth. Essentially the whole enzyme is localized in periplasmic fraction. Cells Desulfovibrio desulfuricans B-1388 do not show the catalase activity but contain active NADH- and NADPH-peroxidases. The activity of involved peroxidases depends on the physiological condition of culture.
