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

2. Physiology and Genetics of Acidithiobacillus species : Applications for Biomining
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

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

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
