By Sulfate Reducing Bacteria Of Acid Mine

Acidic mine drainage AMD is regarded as a pollutant and considered as potential source of valuable metals. With diminishing metal resources and everincreasing demand on industry recovering AMD metals is a sustainable initiative despite facing major challenges. AMD refers to effluents draining from abandoned mines and mine wastes usually highly acidic that contain a variety of dissolved

Dust andacid mine water were prepared as described above. Sodiumlactate was addedto the flask to give a 0.1 concentration wv and the mixed cultures were seeded with 25 ml of a 7day culture ofmixed sulfatereducing bacteria to increase the population of sulfatereducing bacteria. The cultures were incubated at 37 C. ORpH and dissolved

20061115Sulfatereducing bioreactors use special forms of bacteria to remove metals of AMD and add alkalinity. These bacteria convert sulfate an ion present in AMD into both sulfide and bicarbonate. The sulfide then combines with dissolved metals to create an insoluble compound that drops out of

Sulfatereducing bacteria SRB are bacteria that can obtain energy by oxidiing organic compounds or molecular hydrogen while reducing sulfate to hydrogen sulfide. Most sulfatereducing bacteria can also reduce other oxidied inorganic sulfur compounds such as sulfite thiosulfateelemental sulfur.

2020312Acid mine drainage AMD characteried by low pH and high concentrations of sulfate and heavy metals is an important and widespread environmental problem related to the mining industry. Sulfatereducing passive bioreactors have received much attention lately as
