1. Analysis and speciation of organic phosphorus in environmental matrices : Development of methods to improve 31P NMR analysis
Abstract : Phosphorus (P) is an essential element for life on our planet. It is central in numerous biochemical processes in terrestrial and aqueous ecosystems including food production; and it is the primary growth-limiting nutrient in some of the world’s biomes. READ MORE

2. The Story of Phosphorus : Sustainability implications of global phosphorus scarcity for food security
Abstract : The story of phosphorus began with the search for the philosopher’s stone, and centuries later the critical role of phosphorus in soil fertility and crop growth was highlighted. Eventually, phosphorus was implicated in the global environmental challenge of eutrophication. READ MORE

3. Organic Phosphorus Compounds in Aquatic Sediments : Analysis, Abundance and Effects
Abstract : Phosphorus (P) is often the limiting nutrient in lacustrine and brackish eco-systems, and enhanced input of P into an aquatic system might therefore negatively impact the environment. Because modern waste water manage-ment have reduced external P input to surface waters, internal P loading from the sediment has become one of the main P sources to aquatic ecosys-tems, in which relatively unknown organic P compounds seem to be more active in P recycling than previously thought.

4. Metabolic analysis of shikimic acid producing Escherichia coli
Abstract : Shikimic acid production using recombinant E.coli has been developed during the past 15 years due to the increased demand of this product, primarily as a starting material for the anti-influensa medicine Tamiflu?. A detailed metabolic analysis of a shikimic acid producing E. READ MORE

5. Wastewater treatment in constructed wetlands : Effects of vegetation, hydraulics and data analysis methods
Abstract : Degradation of water resources has become one of the most pressing global concerns currently facing mankind. Constructed Wetlands (CWs) represent a concept to combat deterioration of water resources by acting as buffers between wastewater and receiving water bodies. READ MORE
