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. Inductively Coupled Plasma Spectrometry for Speciation Analysis : Development and Applications

   Author : Niklas Forsgard; Jean Pettersson; Marit Andersson; Jonas Bergquist; Walter Lund; Uppsala universitet; []
   Keywords : Analytical chemistry; Speciation analysis; Atomic emission spectrometry AES ; Mass spectrometry MS ; Inductively coupled plasma ICP ; Liquid Chromatography LC ; on-line sample pre-treatment; Organic phosphour; Siderophores; Slurry nebulization; matrix effects; Analytisk kemi;

   Abstract : In analytical chemistry the main goal is normally to determine the identity and/or concentration of one or more species in a sample. The samples analyzed are often natural samples, containing numerous different species in a complex matrix and the choice of technique for multi-elemental detection is in general inductively coupled plasma spectrometry.

6. 4. On the investigation of chemical parameters reflecting microbial activity linked to nutrient availability in forest soil

   Author : Madelen Olofsson; Dan Bylund; Bengt-Gunnar Jonsson; Bjarne W. Strobel; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Boreal forest; electrospray ionization; fungal biomass; hydrophilic interaction chromatography; hydroxamate siderophores; liquid chromatography-mass spectrometry; mineral amendment; aromatic acids; podzol soil;

   Abstract : As agrarian society developed, the most fertile soils able to sustain the nutritional requirements needed for high crop yield were assigned to farming, while the more penurious soils were left to uphold the forest ecosystems. Some temperate forests are developed on acidic soils considered to be nutrient poor, as much of the inorganic nutrients are entrapped in poorly weatherable soil minerals and not easily accessed by plant roots.
