2. 1. Microbe-mineral interactions in soil : Investigation of biogenic chelators, microenvironments and weathering processes

   Author : Engy Ahmed; Sara Holmström; Roger Finlay; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Podzol; Biotite; Apatite; Oligoclase; Microbial attachment; Siderophores; Soil microorganisms; geokemi; Geochemistry;

   Abstract : The interplay between geology and biology has shaped the Earth during billions of years. Microbe-mineral interactions are prime examples of this interplay and underscore the importance of microorganisms in making Earth a suitable environment for all forms of life. READ MORE

4. 2. Plant-microbe-soil interactions and soil nitrogen dynamics in boreal forests : development of nitrogen limitation

   Author : Robert Blasko; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Widespread nitrogen (N) limitation of plant growth in boreal forests is a well recognized phenomenon. Yet, the mechanisms responsible for the development of N limitation are unknown. By exploring the linkage between N cycling and microbial community structure, this thesis examines the role of soil microorganisms in N limitation development. READ MORE

5. 3. Abiotic stress and plant-microbe interactions in Norway spruce

   Author : Julia Christa Haas; Vaughan Hurry; Nathaniel Street; Torgny Näsholm; Jennifer Baltzer; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Norway spruce; boreal forest; cold; drought; bacteria; fungi; plant-microbe interactions; climate change;

   Abstract : Norway spruce (Picea abies) is a dominant tree species in boreal forests with extensive ecological and economic value. Climate change is threatening these ecosystems, with rising temperatures impacting cold hardening and increasing drought stress in regions experiencing lower precipitation. READ MORE

6. 4. Quantitative monitoring of microorganisms in environmental samples using biomarkers

   Author : Annelie Elväng; James Prosser; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

   Abstract : The use of microorganisms in environmental biotechnology is an area of growing interest. Microorganisms have been used for diverse applications, such as biological fertilizers, biological pesticides and bioremediation of toxic chemicals. In many cases, the bacteria of interest have been genetically alterred to improve certain traits. READ MORE

7. 5. Development of molecular techniques for fungal diagnostic research

   Author : Qing-Yin Zeng; Åsa Rasmuson-Lestander; Xiao-Ru Wang; Aino Nevalainen; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Fungi; DNA markers; Aerosols; Detection and quantification; Environmental monitoring; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

   Abstract : Fungi are present everywhere in indoor and outdoor environments. Many fungi are toxigenic or pathogenic that may cause various public health concerns. Rapid detection, quantification and characterization of fungi in living and working environments are essential for exposure risk assessment to safe guard public health. READ MORE
