Title Pitfalls of passive mine water treatment Type Journal Article
Year 2002 Publication Reviews in Environmental Science & Biotechnology Abbreviated Journal
Volume 1 Issue 5 Pages 335-343
Keywords acid mine drainage acidophilic microorganisms heavy metals iron oxidation iron reduction remediation sulfate reduction wetlands Wheal Jane
Abstract Passive (wetland) treatment of waters draining abandoned and derelict mine sites has a number of detrac-tions. Detailed knowledge of many of the fundamental processes that dictate the performance and longevity of constructed systems is currently very limited and therefore more research effort is needed before passive treatment becomes an “off-the-shelf” technology.

Title Asidik maden drenajinin (AMD) giderilmesinde uygulanan biyolojik yontemler. Biological methods applied in the treatment of acid mine drainage (AMD) Type Journal Article
Year 2006 Publication Madencilik = The = Journal of the Chamber of Mining Engineers of Turkey Abbreviated Journal
Volume 45 Issue 1 Pages 35-45
Keywords acid mine drainage biodegradation methods microorganisms oxidation pollutants pollution remediation sulfides 22, Environmental geology
Abstract Acidic mine drainage (AMD) is a serious environmental problem in mining areas throughout the world. AMD occurs as a result of the natural oxidation of sulfide minerals when they are exposed to oxygen and water during their disposal and storage at the mining areas. Because it includes low pH and high concentrations of dissolved metals and sulphates, AMD can potentially damage to the environment. If the formation of AMD can't be prevented and controlled, it must be collected and treated to remove acidity and reduce the concentration of heavy metals and suspended solids before its release to the environment. Different types of microorganisms in the treatment of AMD can play a very important role in the development and the application of microbiological prevention, control and treatment technologies. The purpose of this article is to give information about the passive biological methods used in the treatment and the control of AMD and the role of microorganisms in these methods.

Title Evaluation of the beneficial effects of the acidophilic alga Euglena mutabilis on acid mine drainage systems Type Book Whole
Year 2002 Publication Abbreviated Journal
Volume Issue Pages
Keywords acid mine drainage atmospheric precipitation benthic taxa bioremediation dissolved materials dissolved oxygen electron microscopy data Euglena mutabilis Green Valley Mine ICP mass spectra Indiana iron mass spectra metals microorganisms mines oxygen pH photochemistry photosynthesis pollution rain remediation sediments soils spectra temperature United States Vigo County Indiana water 22, Environmental geology
Abstract Euglena mutabilis is an acidophilic, photosynthetic protozoan that forms benthic mats in acid mine drainage (AMD) channels. At the Green Valley mine, western Indiana, E. mutabilis resides in AMD measuring <4.2 pH, with high concentrations of dissolved constituents (up to 22.67 g/l). One of the main factors influencing E. mutabilis distribution is water temperature. The microbe forms thick (>1 mm), extensive mats during spring and fall, when water temperature is between 13 and 28 degrees C. During winter and summer, when temperatures are outside this range, benthic communities have a very patchy distribution and are restricted to areas protected from extreme temperature changes. E. mutabilis also responds to rapid increases in pH, which are associated with rainfall events. During these events pH can increase above 4.0, causing precipitation of Fe and Al oxy-hydroxides that cover the mats. The microbe responds by moving through the precipitates, due to phototaxis, and reestablishing the community at the sediment-water interface within 12 hours. The biological activities of E. mutabilis may have a beneficial effect on AMD systems by removing iron from effluent via oxygenic photosynthesis, and/or by internal sequestration. Photosynthesis by E. mutabilis contributes elevated concentrations of dissolved oxygen (DO), up to 17.25 mg/l in the field and up to 11.83 mg/l in the laboratory, driving oxidation and precipitation of reduced metal species, especially Fe (II), which are dissolved in the effluent. In addition, preliminary electro-microscopic and staining analyses of the reddish intracellular granules in E. mutabilis indicate that the granules contain iron, suggesting that E. mutabilis sequesters iron from AMD. Inductive coupled plasma analysis of iron concentration in AMD with and without E. mutabilis also shows that E. mutabilis accelerates the rate of Fe removal from the media. Whether iron removal is accelerated by internal sequestration of iron and/or by precipitation via oxygenic photosynthesis has yet to be determined. These biological activities may play an important role in the natural remediation of AMD systems.
