Area of Science:

• Microbiology
• Environmental Science
• Biotechnology

Background:

• Accelerating discovery of obligate anaerobic bacteria highlights underestimated anoxic biotransformation diversity.
• Many anaerobes, including archaebacterial and eubacterial hyperthermophiles, thrive in extreme environments.
• Energy conservation occurs via fermentation, anoxygenic photophosphorylation, and anaerobic respiration using various electron acceptors.

Purpose of the Study:

• To explore the diverse biochemical capacities and environmental roles of obligate anaerobic bacteria.
• To illustrate the biotechnological potential of anaerobic bacteria in biodegradation, biosynthesis, and biotransformation.
