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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

    Author : Stefanie Mangold; Mark Dopson; Axel Schippers; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE
