  1. 21. Anaerobic Digestion – Microbial Ecology, Improved Operational Design and Process Monitoring

    Författare :Marika Murto; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; monitoring; UASB; Biotechnology; Bioteknik; methanogens; fluorescence in situ hybridisation; FISH; co-digestion; biogas; biofilm; aqueous two phase system; anaerobic digestion; 16S rDNA; alkalinity;

    Sammanfattning : The implementation of anaerobic digestion is important in the concept of sustainable development, especially regarding the environmental benefits. Biogas is produced when organic matter is degraded by microorganisms under oxygen-free (anaerobic) conditions. LÄS MER

  3. 22. Aqueous Block Copolymer Systems. Self-association, Phase Behaviour and Partitioning of Biomolecules

    Författare :Mårten Svensson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; block copolymer self-association partitioning phase behaviour; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The phase and partitioning behaviour of aqueous block copolymer systems has been studied. The block copolymers used in this work were built up of three blocks. The middle block was poly(propylene oxide) (PPO) and hydrophobic. The two outer blocks constisted of poly(ethylene oxide) (PEO) chains and less hydrophobic. LÄS MER

  4. 23. Phosphatidylinositol 4-kinases in plasma membranes and Affinity partitioning of liposomes: a model system for membrane purification

    Författare :Lars Ekblad; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; metabolism; Biokemi;

    Sammanfattning : Polyphosphoinositides, the different phosphorylated variants of the phospholipid phosphatidylinositol (PtdIns), are used in a wide array of intracellular mechanisms in eukaryotic cells. The phosphorylation of PtdIns at carbon D4, catalyzed by phosphatidylinositol 4-kinase, is an important step in the synthesis of several of these molecules. LÄS MER

  5. 24. A comparative study on sugar beet root (Na⁺+K⁺)MgATPases isolated by different methods

    Författare :Göran Wingstrand; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Msiribrane bound (Na+ + K+)MgATPases from homogenates of young sugar beet roots were prepared either by differential centrifugations or by an aqueous two-phase system. The properties of the MgATPases were deter- mined in the preparations. Potassium [K (° Rb )] uptake into roots of intact sugar beets was also studied. LÄS MER

  7. 25. A model for membrane organization and protein sorting in the cyanobacterium Synechocystis sp. PCC 6803

    Författare :Tatiana Pisareva; Birgitta Norling; Colin Robinson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; biokemi;

    Sammanfattning : Cyanobacteria constitute a unique group of eubacteria, possessing outer and plasma membranes as well as internal thylakoid membranes, the site for both photosynthesis and respiration. The combination of sucrose density centrifugation and two-phase partitioning methods leads to purification of different membranes from the cyanobacterium Synechocystis sp. LÄS MER
