1. 1. A passage to wastewater nutrient recovery units : Microalgal-Bacterial bioreactors

   Författare :Anbarasan Anbalagan; Jesus Zambrano; Sebastian Schwede; Carl-Fredrik Lindberg; Emma Nehrenheim; Francisco Gabriel Acién Fernández; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microalgae; Bacteria; Carbon; Nitrogen; Light; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : In recent years, the microalgal–bacterial process has been considered to be a very attractive engineering solution for wastewater treatment. However, it has not been widely studied in the context of conventional wastewater treatment design under Swedish conditions. LÄS MER

3. 2. 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

4. 3. Boreal Lake Sediments as Sources and Sinks of Carbon

   Författare :Cristian Gudasz; Tranvik Lars; David Bastviken; Susan Ziegler; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boreal lakes; allochthonous; lake sediments; sediment mineralization; bacterial production; bacterial biomass; carbon cycle; Freshwater ecology; Limnisk ekologi; Limnologi; Limnology;

   Sammanfattning : Inland waters process large amounts of organic carbon, contributing to CO2 and CH4 emissions, as well as storing organic carbon (OC) over geological timescales. Recently, it has been shown that the magnitude of these processes is of global significance. LÄS MER

5. 4. Enzymes for selective decoupling of woody biomass: From fundamentals to industrial potential

   Författare :Jenny Arnling Bååth; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignocellulose; glucuronoyl esterase; polysaccharide acetylation; carbohydrate esterase family 15; woody biomass; materials biorefinery; enzyme accessibility; lignin-carbohydrate bonds; mannanase; galactoglucomannan;

   Sammanfattning : The need for an economy based on renewable materials has resulted in growing interest in the use of woody biomass in a wider field of application. However, the chemical complexity of lignocellulose and the dense structure of wood pose challenges in its processing. LÄS MER

7. 5. Bacterial and fungal growth in soil: The effect of temperature and substrate addition

   Författare :Stephanie Reischke; MEMEG; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bacterial growth; Fungal growth; Respiration; Carbon loading; Glucose mineralisation; Temperature adaptation; Temperature sensitivity; Temperature dependence;

   Sammanfattning : Bacteria and fungi are the main agents in decomposition of soil organic matter. Their activity is determined by the availability and quality of substrate, especially its content of carbon, but also nitrogen and phosphorus. Other environmental factors, which affect the activity of the microbial community in soil, are temperature, moisture and pH. LÄS MER
