Aerobic incubation of Halobacterium halobium with low concentrations of cyanide or azide resulted in a twofold increase in activity of the Mn-containing superoxide dismutase (SOD). A similar effect was observed with antimycin A, albeit at a higher concentration. Oxygen consumption increased 100% at concentrations of cyanide, azide, and antimycin A that produced maximal SOD induction. Luminol chemiluminescence of H. halobium cells, indicative of oxidative activity, was elevated in the presence… CONTINUE READING
