Cyanide is a chemical used to dissolve gold and is harmful to the environment and organisms living there.A couple of biochemists came up with the idea of using the bacteria in the genus Pseudomonas to break down the cyanide used by a gold mining company.Which term refers to this use of bacteria?
A)bioremediation
B)immunoextraction
C)decomposition
D)bioextraction
E)biosynthesis

Bioremediation refers to the use of organisms, such as bacteria, to break down or neutralize harmful substances in the environment. In this case, the biochemists are using Pseudomonas bacteria to break down the cyanide used in gold mining, which is a form of bioremediation. Immunoextraction involves using antibodies to specifically extract or bind to certain molecules, which is not relevant in this scenario. Decomposition refers to the natural breakdown of organic matter and is not specific to breaking down harmful substances. Bioextraction refers to the process of extracting metals or minerals from organic sources, which is not the same as breaking down cyanide. Biosynthesis refers to the production of new biomolecules by living organisms and is also not relevant in this scenario.
