ABSTRACT: Strictly anaerobic bacteria in the
evolutionary way formed some mechanisms of oxygen tolerance. These changes
enable strictly anaerobic bacteria existing in natural environment in which
avoiding oxygen is not possible. Clostridium
bifermentans is described as a strictly anaerobe species; however, in the literature, there is some information about its oxygen
tolerance. Thus, in this work, the level of C. bifermentans aero-tolerance, its mechanisms, and the ability to
metabolite production in presence of oxygen in cultivation medium were
investigated. It was found out that C.
bifermentans is able to survive in the presence of oxygen.
Moreover, they are able to utilize oxygen and product metabolites when the
level of oxygen is below 10%. In bacteria cells superoxide dismutase was
detected.
