1. 1. Physiology and Genetics of Acidithiobacillus species : Applications for Biomining

   Författare :Olena Rzhepishevska; Mark Dopson; Wolfgang Sand; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Mikrobiologi;

   Sammanfattning : Bacteria from the genus Acidithiobacillus are often associated with biominingand acid mine drainage. Biomining utilises acidophilic, sulphur and ironoxidising microorganisms for recovery of metals from sulphidic low grade oresand concentrates. LÄS MER

3. 2. Function and Adaptation of Acidophiles in Natural and Applied Communities

   Författare :Stephan Christel; Mark Dopson; Michael Schlömann; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acidophiles; Biomining; Psychrophiles; Adaptation; Acid Sulfate Soil; Redox Control; Ecology; Ekologi;

   Sammanfattning : Acidophiles are organisms that have evolved to grow optimally at high concentrations of protons. Members of this group are found in all three domains of life, although most of them belong to the Archaea and Bacteria. LÄS MER

4. 3. Genomics, physiology and applications of cold tolerant acidophiles

   Författare :Maria Liljeqvist; Mark Dopson; Ricardo Amilis; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Psychrotolerant acidophiles have gained increasing interest because of their importance in biomining operations in environments where the temperature falls well below 10°C during large parts of the year.Acidithiobacillus ferrivorans is the only characterized acidophile with the ability to live a psychrotrophic lifestyle and is able to oxidize ferrous iron and inorganic sulfur compounds at low temperature.
