1. Microbial ecology in deep granitic groundwater - activity and impact of viruses
Abstract : The deep subsurface environments in granitic rock can be studied and sampled at the Äspö hard rock laboratory (HRL) close to Oskarshamn in Sweden. Here, the groundwater is anaerobic and total counts give numbers of 104 to 106 cells mL-1. However, these measurements do not reveal if the cells are active and alive. READ MORE

2. Microbial Treatment of Heavy Metal Leachates
Abstract : Ore-mining, metallurgy and other industrial activities represent the source of heavy metal and radionuclide contamination in terrestrial and aquatic environments. Physico-chemical processes are employed for heavy metal removal from industrial wastewater. READ MORE

3. Microbial remediation of heavy metal ion polluted soil and water
Abstract : Contamination of soil and water by heavy metal ions (HMs) is a problem all over the world.The use of biological methods alone or in combination with other techniques for treatment of such polluted sites constitutes a major challenge. READ MORE

4. Precipitation and fixation of uranium in reduced environment : simulation in a continuous culture of sulfate-reducing bacteria
Abstract : The precipitation and fixation of the uranyl ion (U022+), in a reduced environment, has been investigated by means of continuous cultivation of sulphate-reducing bacteria. The continuous culture sustem made it possible to study the chemical reactions under physico-chemical conditions (e.g. READ MORE

5. Environmental and climatic changes in the Baltic Sea and the eastern Mediterranean Sea : as recorded by pigments and isotopes in sediments
Abstract : This thesis is a study of Holocene sapropels from two semi-enclosed seas; the Baltic Sea and the Mediterranean Sea. Sapropels are sedimentary layers with organic C > 2%. READ MORE
