Distribution of thiobacillus ferrooxidans and leptospirillum ferrooxidans: implications for generation of acid mine drainage
Although Thiobacillus ferrooxidans and Leptospirillum ferrooxidans are widely considered to be the microorganisms that control the rate of generation of acid mine drainage, little is known about their natural distribution and abundance. Fluorescence in situ hybridization studies showed that at Iron Mountain, California, T. ferrooxidans occurs in peripheral slime-based communities (at pH over 1....
متن کاملIsolation and Characterization of Thiobacillus ferrooxidans from Coal Acid Mine Drainage
Coal mine drainage refers to the acidic drainage caused by surface mining, deep mining or coal refuse piles. Being highly acidic with elevated levels of dissolved metals, it is otherwise known as “Acid Mine Drainage (AMD)”. Formation of AMD is due to a series of geochemical and microbiological processes involving acidophilic chemolithotrophs such as Thiobacillus, Thiomispora, Leptospirillum etc...
متن کاملGrowth Kinetics of Thiobacillus ferrooxidans Isolated from Arsenic Mine Drainage.
Thiobacillus ferrooxidans is found in many Alaskan and Canadian drainages contaminated by metals dissolved from placer and lode gold mines. We have examined the iron-limited growth and iron oxidation kinetics of a T. ferrooxidans isolate, AK1, by using batch and continuous cultures. Strain AK1 is an arsenic-tolerant isolate obtained from placer gold mine drainage containing large amounts of dis...
متن کاملReliable Mine Water Technology
Mine planning, permitting and operation require reliable water technology in all its aspects: water inflow, water use, water disposal and discharge, and water impact. Mine water evaluations are relied upon by mining companies, mine regulators and the public to determine whether the mine is technically feasible, optimally designed, financially sound, socially acceptable, and environmentally beni...
متن کاملGrowth of Thiobacillus ferrooxidans on Formic Acid.
A variety of acidophilic microorganisms were shown to be capable of oxidizing formate. These included Thiobacillus ferrooxidans ATCC 21834, which, however, could not grow on formate in normal batch cultures. However, the organism could be grown on formate when the substrate supply was growth limiting, e.g., in formate-limited chemostat cultures. The cell densities achieved by the use of the lat...
