2. 1. On thermodynamic and kinetic constraints in autotrophic metabolism

   Author : Markus Janasch; Elton P. Hudson; Bas Teusink; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; autotrophic metabolism; cyanobacteria; microbial metabolic engineering; computational systems biology; biochemical thermodynamics; kinetic modelling; Bioteknologi; Biotechnology;

   Abstract : Earth has entered a new geological epoch, the Anthropocene, defined by humanity’s impact on the environment with increased emissions of CO2 due to burning of fossil resource as a major contributor. To ensure a sustainable future, humanity has to move towards a circular economy, where released CO2 is re-captured and turned into resources. READ MORE

   Abstract : Carbon dioxide (CO2) emissions from human activities are driving climate change, but the pending crisis could be mitigated by a circular carbon economy where released CO2 is recycled into commodity chemicals. Autotrophic microbes can make a contribution by producing chemicals, such as biofuels, from CO2 and renewable energy. READ MORE

5. 3. Systems biology techniques show high prevalence of post-translational regulation in the cyanobacterium Synechocystis PCC 6803

   Author : Jan Karlsen; Elton Paul Hudson; Martin Hagemann; KTH; []
   Keywords : systems biology; sustainable development; omics; ribosome profiling; RNA sequencing; proteomics; genetic engineering; bioproduction; cyanobacteria; gene regulation; metabolism; translational regulation; post-translational regulation; bioinformatics; Bioteknologi; Biotechnology;

   Abstract : Earth's climate has been upset by carbon dioxide (CO2) emissions from human activities and the use of fossil resources. To prevent catastrophic events on the environment and on civilizations, we urgently need to develop alternative solutions that utilize renewable resources. READ MORE

6. 4. Carbon metabolism in clear-water and brown-water lakes

   Author : Jenny Ask; Jan Karlsson; Mats Jansson; Rolf Vinebrooke; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; clear-water lakes; brown-water lakes; primary production; bacterial production; benthic; pelagic; net ecosystem production; allochthonous organic carbon; CO2; DOC; Physical geography; Naturgeografi; Freshwater ecology; Limnisk ekologi; limnologi; Limnology; naturgeografi; Physical Geography;

   Abstract : The trophic state of lakes is commonly defined by the concentration of nutrients in the water column. High nutrient concentrations generate high phytoplankton production, and lakes with low nutrient concentrations are considered low-productive. READ MORE

7. 5. 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.
