   Sammanfattning : Better utilization of renewable sources of energy and recovery of resources from waste streams are important challenges for researchers. Bioelectrochemical systems (BESs) are new technologies which e.g. could be used to produce green energy from waste sources or store renewable electricity as chemical fuels. LÄS MER

4. 3. Production of polyhydroxyalkanoates in biological treatment of industrial wastewaters

   Författare :Simon Bengtsson; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyhydroxyalkanoates; mixed cultures; glycogen accumulating organisms GAO ; feast and famine; acidogenic fermentation; activated sludge;

   Sammanfattning : In search of more environmentally friendly polymer materials, polyhydroxyalkanoates (PHAs) have been considered as promising candidates. PHAs exhibit a broad range of material properties, can be produced from renewable resources and are completely biodegradable. LÄS MER

   Sammanfattning : Ersättning av förlorade tänder med tandimplantat är numera en vanlig behandlingsmetod med generellt goda resultat. Antalet implantatsystem på den internationella marknaden har ökat kraftigt under senare år. LÄS MER

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

   Författare :Xiaofen Wu; Mark Dopson; Ricardo Amils; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular phylogeny; acid sulfate soils; metal; acidophiles; deep biosphere; oligotrophy; biofilm formation; metagenome; binning; metabolism; Mikrobiologi; Microbiology;

   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.
