Biogeochemical cycles recycle water and natural elements throughout the biosphere to ensure that organisms do not run out of these substances. thiobacillus denitrificans is a specialized species of bacteria that obtains its energy from carbon dioxide and inorganic compounds such as nitrogen in its environment. it is used in bioremediation of groundwater that contains excess nitrate. how does thiobacillus denitrificans bioremediate groundwater?

On edge the answer is B. Denitrification

Thiobacillus denitrificans is a chemolithoautotrophic bacteria which can obtain energy from the oxidation of inorganic compounds like nitrogen, iron or sulphur in their environment. It is an autotrophic denitrifying bacteria that is used in the bioremediation of contaminated groundwater. The process of bioremediation is carried out by the process of denitrification.

Nitrate contamination of groundwater is of high-priority concern. In the process of denitrification by Thiobacillus denitrificans, pyrite acts as the electron donor. Other sulphur minerals also act as electron donors in the process of denitrification and help in bioremediation of the contaminated ground water. The bacteria has also been engineered for nitrate removal in water treatment systems also.
