2. 11. Proteomic profiles and gene expressions in the symbiotically competent cyanobacterium Nostoc sp. PCC 73102

   Author : Liang Ran; Birgitta Bergman; Karl Forchhammer; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nostoc PCC 73102; hormogonia; 2-DE; symbiosis; photo-autotrophy; heterotrophy; cell differentiation; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

   Abstract : Nostoc PCC 73102 is an evolutionary important cyanobacterium with multiple phenotypic traits and symbiotic capacities. Based on two-dimensional gel electrophoresis (2-DE) and MALDI-TOF mass spectrometry, a proteomic approach was developed in order to obtain protein profiles of this symbiotically competent cyanobacterium during three trophic types/life stages: free-living photo-autotrophic and diazotrophic growth conditions, dark heterotrophic conditions and hormogonium formation.

4. 12. Evolutionary genomics of symbiotic fungi

   Author : Balaji Rajashekar; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein family; Symbiosis; Paxillus involutus; Laccaria bicolor; Hydrophobin; Fungi; Ectomycorrhizae; Evolution; Comparative Genomics; Basidiomycetes;

   Abstract : Ectomycorrhizae is a mutualistic association between roots of woody plants and a diverse range of soil fungi. The fungi exchange soil derived mineral nutrients for photosynthetic sugars from the host plant. The mycorrhizal symbioses are commonly found in all forest ecosystems and have a major ecological and economical importance. READ MORE

5. 13. Genomic and morphological diversity of marine planktonic diatom-diazotroph associations : a continuum of integration and diversification through geological time

   Abstract : Symbioses between eukaryotes and nitrogen (N2)-fixing cyanobacteria (or diazotrophs) are quite common in the plankton community. A few genera of diatoms (Bacillariophyceae) such as Rhizosolenia, Hemiaulus and Chaetoceros are well known to form symbioses with the heterocystous diazotrophic cyanobacteria Richelia intracellularis and Calothrix rhizosoleniae.

6. 14. Top-down Methodology to Identify Opportunities for Industrial Symbiosis Partnerships

   Author : Joao Patricio; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular Economy; Top-down methods; Industrial Waste; Recycling; Material Inputs; Industrial Symbiosis;

   Abstract : Industries in Europe are responsible for generating approximately 190 Mtons of waste; a figure which is expected to rise, as a significant increase in the consumption of raw materials is predicted to occur in the near future. This may lead to escalating environmental problems, including resource depletion, soil degradation, and climate change. READ MORE

7. 15. Devices. On Hospitality, Hostility and Design

   Author : Martin Avila; Göteborgs universitet; []
   Keywords : HUMANIORA; HUMANITIES; Device; hospitality; hostility; design; languaging; accident; ecology; symbiosis; autopoiesis; umwelt; Device;

   Abstract : This thesis studies and speculates upon the interrelations of artefacts with human and nonhuman agents. These interrelations form assemblages, some of which have emergent properties, becoming manifestations of processes that we cannot fully control or understand. READ MORE
