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

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

3. When bioelectrochemical systems meet extremophiles, possibilities and challenges
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

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

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