ßRoy Lan #2 KTH 2/29/08 Science Extra Credit Option #1 Written Report 1. How does bioremediation work? a. Bioremediation, first of all means to clean up contaminated water or soil. There are two ways that it works, first up is “anabolism”. This is when the microorganisms take up the carbon and nitrogen from the surrounding area no matter what it is, whether it is soil, water, or air. It then uses the elements it takes away from its environment to make various cell parts. The second way it works is “catabolism”. This is when the microorganisms break down the chemicals around them to make energy for themselves. This then, results in a lack of chemicals around them (less oil) and more energy for them. 2. When is bioremediation the most effective? a. Bioremediation does not work well when it is in contact with mercury or heavy metals. It is the most effective when not in contact with these materials listed above and also when there is plenty of carbon and nitrogen readily available.
