Introduction

- All organisms respire, i.e. have a metabolic mechanism by which they obtain energy. This oxidation-reduction (redox) mechanism requires electrons to be transferred from the electron donor (ie the fuel) to the electron acceptor.
- Carbon compounds are the most common electron donor, although inorganic nitrogen is also a fuel for some bacteria.
- Bacteria can exist in aerobic (with oxygen) and anaerobic (without oxygen) environments.
- Aerobic bacteria that can only use dioxygen (O2) as the electron acceptor are called obligate aerobes.
- Anaerobic bacteria must use something other than dioxygen as an electron acceptor.
- Facultative bacteria can carryout respiration using either aerobic or anaerobic mechanisms.
- We are particularly interested in anaerobic bacteria.
