  1. 1. Sulphur-Utilizing Microorganisms in Biotechnological Applications - Rubber Recycling and Vanadium Reduction

    Detta är en avhandling från Katarina Bredberg, Department of Biotechnology, Lund University

    Författare :Katarina Bredberg; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrococcus furiosus; Acidithiobacillus; microbial vanadium reduction; microbial detoxification; rubber recycling; devulcanization; Biotechnological desulphurization; waste rubber materials; Biotechnology; Bioteknik;

    Sammanfattning : Biotechnological processes offer environmentally friendly and sometimes cost-effective alternatives to traditional chemical and mechanical methods. It is important to take advantages of the opportunities these processes provide to fulfil the demands and expectations of a future environmentally sustainable society. LÄS MER

  2. 2. Quantification of mineral weathering rates in sulfidic mine tailings under water-saturated conditions

    Detta är en avhandling från Stockholm : Institutionen för geologi och geokemi

    Författare :Magdalena Gleisner; Docent Roger Herbert; Professor Emeritus Rolf Hallberg; Dr. Magnus Land; Professor Patrick Crill; Mats Åström; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mine tailings; pyrite; sulfides; weathering; oxygen availability; Acidithiobacillus ferrooxidans; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap;

    Sammanfattning : Tailings are a fine-grained waste product produced during the metal recovery process. Tailings consist mostly of different silicates but also sulfides (e.g. pyrite), since 100 % metal recovery is not possible. LÄS MER

  3. 3. Physiology and Genetics of Acidithiobacillus species Applications for Biomining

    Detta är en avhandling från Umeå : Molekylärbiologi (Teknisk-naturvetenskaplig fakultet)

    Författare :Olena Rzhepishevska; Mark Dopson; Wolfgang Sand; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology Organism biology Microbiology; NATURVETENSKAP Biologi Organismbiologi 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

  4. 4. Growth and survival of Acidithiobacilli in Acidic, metal rich environments

    Detta är en avhandling från Umeå : Umeå Universitet

    Författare :Stefanie Mangold; Mark Dopson; Axel Schippers; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Acidithiobacilli are acidophilic microorganisms that play important roles in many natural processes such as acidification of the environment, influencing metal mobility, and impacting on global sulfur and iron cycles. Due to their distinct metabolic properties they can be applied in the industrial extraction of valuable metals. LÄS MER
