  1. 21. Reactors and biosensors for improved microbial degradation of acetonitrile

    Författare :Kristina Håkansson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Bioteknik; denitrification; nitrification; on-line analysis and control; Clark electrode; biosensor; biofilm process; acetonitrile; microbial degradation;

    Sammanfattning : Biodegradation is becoming an attractive mode of operation for eliminating toxic chemicals released from industrial processes or already present in the environment. One needs, however, not only to identify organisms capable of degrading such chemicals, but also to address the issue of whether these chemicals, after being degraded, will be toxic to the degrading organisms if present in high concentrations.

  3. 22. Instrumentation, Control and Automation in Anaerobic Digestion

    Författare :Jing Liu; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; ICA; automation; control; monitoring; biosensor; instrumentation; anaerobic digestion; biogas;

    Sammanfattning : Anaerobic digestion (AD) is a biochemical process in nature. It has been used to decompose organic waste in order to reduce environmental pollution, and to destroy pathogenic microorganisms for the protection of human and animal health. The process itself produces methane, which can then be used as an energy source. LÄS MER

  4. 23. Phospholipid membranes in biosensor applications : Stability, activity and kinetics of reconstituted proteins and glycolipids in supported membranes

    Författare :Inga Gustafson; Gertrud Puu; Sven Lindskog; Peter Konradsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Phospholipid films; Liposomes; Membrane proteins; Glycolipids; Ellipsometry; Langmuir Blodgett LB ; Surface plasmon resonance SPR ; Resonant mirror RM ; Atomic force microscopy AFM ; Biosensors; Biokemi; Biochemistry; Biokemi; Biochemistry; biokemi;

    Sammanfattning : In this study the formation of supported membranes onto planar solid supports has been investigated. The stability and activity of reconstituted membrane receptors has been studied. The potential use of such preparations in biosensor applications is discussed.The lipid films were made by the Langmuir Blodgett and by the liposome fusion techniques. LÄS MER

  5. 24. Protein-based capacitive biosensors for the detection of heavy-metal ions

    Författare :Alessia Mortari; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy metal ions; protein; electrode; Biosensor; capacitance;

    Sammanfattning : Some metal ions, such as copper and zinc, are essential nutrients and catalysts in biochemical reactions. Other metal ions, e.g. cadmium and mercury, are highly toxic elements. LÄS MER

  7. 25. Characterisation of starch: development of analytical methods

    Författare :Gunilla Nilsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; substitution pattern; microdialysis; HPAEC-PAD; NMR; biosensor; IMER; potato amylopectin starch; amylose; amylopectin; chain length; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Starch, comprised of amylose and amylopectin, is a very complex biopolymer. Different methods are therefore needed for the investigation of the molecular structures of amylose and amylopectin. In this thesis analytical methods have been developed and various techniques were combined for the characterisation of starch. LÄS MER
