2. 1. Antibiotic Resistance in Wastewater : Methicillin-resistant Staphylococcus aureus (MRSA)and antibiotic resistance genes

   Author : Stefan Börjesson; Per-Eric Lindgren; Johanna Ericson Sollid; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MRSA; SCCmec; spa typing; Staphylococcus aureus; methicillin; B-lactam; aminoglycoside; tetracycline; antibiotic; wastewater; wastewater treatment plant; Microbiology; Mikrobiologi;

   Abstract : A large part of the antibiotics consumed ends up in wastewater, and in the wastewater the antibiotics may exert selective pressure for or maintain resistance among microorganisms. Antibiotic resistant bacteria and genes encoding antibiotic resistance are commonly detected in wastewater, often at higher rates and concentrations compared to surface water. READ MORE

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

   Author : Lorenza Ferro; Christiane Funk; Francesco Gentili; Luísa Gouveia; Umeå universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

5. 3. Characterization of Bacterial Biofilms for Wastewater Treatment

   Author : Sofia Andersson; Gunnel Dalhammar; Bo Mattiasson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biofilm; extracellular polymeric substances; exopolysaccharides; interspecies interactions; wastewater treatment; denitrification; phosphorus removal; Microbiology; Mikrobiologi;

   Abstract : Research performed at the Division of Environmental Microbiology has over the last years resulted in the isolation of possible bacterial key-organisms with efficient nutrient removal properties (Comamonas denitrificans, Brachymonas denitrificans, Aeromonas hydrophila). Effective use of these organisms for enhanced nutrient removal in wastewater treatment applications requires the strains to be retained, to proliferate and to maintain biological activity within theprocess.

6. 4. Treatment of domestic wastewater using microbiological processes and hydroponics in Sweden

   Author : Anna Norström; Gunnel Dalhammar; Jörgen Hanaeus; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; biological; hydroponics; microbial composition; nitrogen; organic matter; phosphorus; small scale; theoretical energy requirements; wastewater treatment.; Mikrobiologi; Microbiology; Mikrobiologi;

   Abstract : Conventional end-of-pipe solutions for wastewater treatment have been criticized from a sustainable view-point, in particular regarding recycling of nutrients. The integration of hydroponic cultivation into a wastewater treatment system has been proposed as an ecological alternative, where nutrients can be removed from the wastewater through plant uptake; however, cultivation of plants in a temperate climate, such as Sweden, implies that additional energy is needed during the colder and darker period.

7. 5. Microbial communities in anammox and nitrifying biofilms

   Author : Carolina Suarez; Göteborgs universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; biofilms; AOB; partial nitritation anammox; nitrification; wastewater;

   Abstract : Excess of nitrogen in water bodies causes eutrophication. One important source of nitrogen is the effluent from wastewater treatment plants (WWTPs). Nitrogen in wastewater is most commonly removed by nitrification-denitrification. READ MORE
