1. Phylogenetic characterization of microbial mats and isolation of Thermus spp. and sulfur-oxidizing bacteria from Icelandic hot springs
Abstract : Until recently, the only way to describe microbial communities was by cultivation. This is a major obstacle because typically only a small fraction of the microbes can be cultivated by standard techniques. However, the use of rRNA and molecular phylogenetic techniques has allowed us to bypass this limitation. READ MORE

2. Bacteria-sulfide mineral interactions with reference to flotation and flocculation
Abstract : Biological processes have been attracting attention in mineral processing industry due to their lower operating costs, environmental acceptability and flexibility in adaptation. Bio-hydrometallurgical methods to treat various sulfide and oxide ores have been developed during the years and these processes have been adopted by certain industries. READ MORE

3. Microbial biofilm communities associated with degradation of sprayed concrete in subsea tunnels
Abstract : Deterioration of concrete leads to reduced structural strength implying high societal challenge with huge economic impact. In the Oslofjord subsea tunnel, complex microbial biofilm activity together with abiotic attack from saline groundwater are responsible for concrete matrix degradation and steel fiber corrosion.

4. 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
