Question

A specific enzyme can be used in in industrial food processing to clean food residues from machinery. This process works best at pH 3 and 180 degrees F. A researcher decides to go bioprospecting to find a microbe that will produce an enzyme that works under these conditions. Given that a microbe’s enzymes usually function best in conditions similar to those in which it lives, which bacterium would be the best choice as the source of the “cleaning” enzyme for this process? A bacterium found in:

a. a neutral (pH 7) forest soil in the Arctic

b. an acidic (pH 3.5) forest soil in the Arctic

c. an acidic (pH 3.5) hot spring in Yellowstone Park

d. an alkaline (pH 9.5) hot spring in Yellowstone Park

Explanation / Answer

Since we require a bacterium from where we can prepare the enzyme which can be used in food industry that can work at pH 3 and 180 F (~84 C, should be isolated from a bacterium which can survive in similar conditions. Thus option c an acidic pH 3.5 hot spring at yellow stone national park is correct place to identify such bacteria.
