1. Structure and function of microbial communities in acid sulfate soil and the terrestrial deep biosphere
Sammanfattning : 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.

2. Baltic Sea sediments : Source and sink for metal contamination
Sammanfattning : The Baltic Sea sediments record spatial and temporal information about metalsand metalloids (hereafter referred to as metals), which could help to understandthe past and present contamination sinks in different basins. In addition, giventhe expanding anoxic zones in the Baltic Sea, the response of metals to artificialreoxygenation is poorly understood. LÄS MER
3. Function and Adaptation of Acidophiles in Natural and Applied Communities
Sammanfattning : 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. LÄS MER
4. Green Liquor Dregs in Sealing Layers to Prevent the Formation of Acid Mine drainage : From characterization to implementation
Sammanfattning : One of the mining industry’s main concerns is the management of waste rock and tailings generated by sulfide ore extraction. Upon exposure to atmospheric oxygen, iron sulfides oxidize producing acidity. LÄS MER
