Bacteria in industry. However, this reaction is tremendously accelerated by the acidophilic lithotrophic bacterium Acidithiobacillus ferrooxidans. When pyritic (ferrous sulfide) deposits are exposed to the air by mining operations, there is slow spontaneous oxidation of pyrite to ferrous ions and sulfuric acid.

A number of plant growthpromoting bacteria have been found to contain the enzyme ACC deaminase, which cleaves and sequesters the plant ethylene precursor ACC and thus lowers the level of ethylene in a developing or stressed plant . The presence of plant growthpromoting bacteria thereby moderates concentration of ACC so that it does not reach a level where it begins to impair root growth.

Oct 04, 2004· A long history of mining in the Pacific Northwest has led to high levels of heavy metals in the sediments of some area lakes and rivers. However, microorganisms that live in these metalcontaminated sediments, such as those in Lake Coeur d'Alene, are capable of detoxifying their environment and thus constitute an important factor in the biogeochemical cycles of these metals.
