2. The Nutritional Requirements of Bacteria

3. Cellular Respiration Bacteria can be distinguished from one another for either their requirement for or lack of oxygen to function. Aerobic bacteria require oxygen in order to function efficiently, while anaerobic bacteria require an absence of it to do the same.

4. Specialized Bacteria Some aerobes and anaerobes can only live in their specific environment and will die if exposed to the other. These type of bacteria are called obligate aerobes and obligate anaerobes

5. Bacterial by products When aerobic bacteria become starved of air, they produce lactic acid which hinders the function of the organism. In anaerobic bacteria the process is called fermentation. Fermentation produces ethyl alcohol which gets us stuff like beer

6. Heterotrophics and autotrophics Heterotrophic bacteria are bacteria which get their nutrients from the environment (they eat) Autotrophic bacteria on the other hand rely on an energy source to make the required nutrients. Some autotrophics are photosynthetic which use the sun to make food, and others are chemosynthetic which require chemicals for an energy source to produce nutrients. An example of this are deep sea thermal vents which host a multitude of chemosynthetic bacteria.
