Redox potential metabolic mode

The most critical issue to be investigated during the initial biofeasibility study is the determination of which metabolic mode—aerobic or anaerobic—is more appropriate for the specific contaminants. As shown in Table 14.5, the redox potential is closely related to the metabolic mode, and careful control of this parameter is required to maintain the optimum metabolic mode during bioremediation. A general rule is that the redox potential should be above 50 mV to maintain the activity of aerobic and facultative anaerobic microorganisms and below that value for strictly anaerobic m icroorganisms.12... [Pg.539]

Mode of action Metronidazole is selectively toxic not only for amebae but also for anaerobic organisms (including bacteria), and for anoxic or hypoxic cells. Some anaerobic protozoan parasites (including amebae) possess ferrodoxin-like, low-redox potential, electron transport proteins that participate in metabolic electron removal reactions. The nitro group of metronidazole is able to serve as an electron acceptor, forming reduced cytotoxic compounds that bind to proteins and DIMA to result in cell death. [Pg.358]
