  1. 1. 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.

  3. 2. Adaptive Evolution of the Bacterial Translation Machinery

    Författare :Arindam De Tarafder; Suparna Sanyal; Michael Y. Pavlov; Ruben L. Jr. Gonzalez; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ribosome; Translation; Translation machinery; Elongation; Evolution; RNA world; Cold bacteria; Molekylär biovetenskap; Molecular Life Sciences;

    Sammanfattning : The process of protein synthesis via translation is of paramount importance for the existence of life on Earth. The bacterial translation machinery has embraced more than 3.5 billion years of molecular evolution to adapt and function efficiently under the provided physiological conditions. LÄS MER

  4. 3. 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
