1. 1. Signalling between plants and microorganisms

   Författare :Ulrika Troedsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; symbiosis; Chitinase; rhizobium; mycorrhiza; plant; glucanase; Biology; Biologi;

   Sammanfattning : Plants and microbes can interact in several ways. Plants can be attacked by different types of pathogens like fungi, virus and bacteria, but can also form symbioses with fungi and bacteria. Certain common antimicrobial proteins are produced by the plants regardless of the type of microbial interaction with the plant. LÄS MER

3. 2. Nutrient balance and salinity stress in arbuscular mycorrhizal fungi

   Författare :Edith Hammer; MEMEG; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inoculum; Glomalin; Fatty acids; Osmolyte; Organic matter; K; Na; Salinity; Symbiotic exchange; Phosphorus P; Carbon C; PIXE; Arbuscular mycorrhizal fungi; Rhizobium;

   Sammanfattning : Earth’s primary production depends to a considerable extent on the mycorrhizal symbiosis, since mycorrhizal fungi supply their host plant with important mineral nutrients. I examined the influence of different nutrient regimes on the fungal partner in the arbuscular mycorrhizal symbiosis. LÄS MER

5. 4. Influence of soil amendments and soil properties on macro– and micronutrient availability to microorganisms and plants

   Författare :Atefeh Ramezanian Bajgiran; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Utilising by-products from industrial and domestic activities and from bioenergy production is one of the new ways of recovering and re-using nutrient resources in agriculture. However, these by-products can potentially add toxic elements or alter soil properties in ways that harm the soil and related environments. LÄS MER

7. 5. Wastewater treatment and biomass generation by Nordic microalgae : growth in subarctic climate and microbial interactions

   Författare :Lorenza Ferro; Christiane Funk; Francesco Gentili; Luísa Gouveia; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microalgae; Wastewater; Nitrogen; Phosphate; Biomass; Lipids; Subarctic Climate; Light; Temperature; Bacteria; Photoautotrophy; Heterotrophy; Mixotrophy; HRAP; Metabarcoding; Microbial Communities; Alpha-diversity; Environmental Factors; Biochemistry; biokemi; mikrobiologi; Microbiology;

   Sammanfattning : Nordic native microalgal strains were isolated, genetically classified and tested for their ability to grow in municipal wastewater. Eight of the isolated strains could efficiently remove nitrogen and phosphate in less than two weeks. Two of these strains, Coelastrella sp. LÄS MER
