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

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

    Abstract : 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. READ MORE

  4. 2. Structure and function of microbial communities in acid sulfate soil and the terrestrial deep biosphere

    Author : Xiaofen Wu; Mark Dopson; Ricardo Amils; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular phylogeny; acid sulfate soils; metal; acidophiles; deep biosphere; oligotrophy; biofilm formation; metagenome; binning; metabolism; Mikrobiologi; Microbiology;

    Abstract : This thesis describes the use of different DNA sequencing technologies to investigate the structure and function of microbial communities in two extreme environments, boreal acid sulfate soil and the terrestrial deep biosphere.The first of the two investigated environments was soils containing un-oxidized metal sulfides that are termed ‘potential acid sulfate soil’ (PASS) materials.

  5. 3. When bioelectrochemical systems meet extremophiles, possibilities and challenges

    Author : Gaofeng Ni; Mark Dopson; Bert Hamelers; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acidophiles; psychrophiles; haloalkaliphiles; bioelectrochemical systems; microbial sulfur metabolism; 16S rRNA gene amplicon sequencing; metagenomics; metatranscriptomics; Mikrobiologi; Microbiology;

    Abstract : Extremophiles are microorganisms live and thrive in extreme environments that are harsh and hostile to most forms of life on earth (e.g. low pH, low temperature, high pH and high salinity). They have developed strategies to obtain nutrients and conserve energy to sustain life under these adverse conditions. READ MORE

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

    Author : Maria Liljeqvist; Mark Dopson; Ricardo Amilis; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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.

  7. 5. 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
