  1. 1. Biotechnological treatment of chlorophenol-contaminated water

    Författare :Hamid Zilouei; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Bioteknik; kontroll av utsläpp; Miljöteknik; pollution control; Environmental technology; Cell-based biosensor; Fluorescence in situ hybridization; Bacterial community; Two-liquid phase partitioning bioreactor; Photolysis pretreatment; Biomonitoring; Fixed-biofilm reactors; Toxic organic pollutant; Biodegradation;

    Sammanfattning : Widespread presence of toxic and persistent pollutants in the environment, even at low concentrations, causes risks of adverse effects to human health and the ecosystem. Biological methods for treatment of water streams and removal of persistent pollutants are of great interest due to their simplicity, low cost, and mild operational conditions without harmful by-products.

  3. 2. 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.

  4. 3. Microfluidic biosensor systems for cardiotoxicity assaying

    Författare :Gunnar Bergström; Carl-Fredrik Mandenius; Nate Robinson; Staffan Nilsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Toxicity screening is an important part of pharmaceutical development and early detection of toxic side effects provide the opportunity for early redesign or termination of unfeasible projects. Today toxicity testing is relying on experiments on animals. LÄS MER

  5. 4. QCM-based sensing using biological and biomimetic interfaces

    Författare :Louise Elmlund; Ian Nicholls; Teodor Aastrup; Jesper Wiklander; Kristina Nilsson-Ekdahl; Håkan Andersson; Susanne Wikman; Alessandra Maria Bossi; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quartz crystal microbalance; molecularly imprinted polymers; phage display; interactions; artificial receptors; recognition; selectivity; Kemi; Chemistry;

    Sammanfattning : The objective of this thesis was to explore novel approaches for studying molecular recognition at biological and biomimetic surfaces using the quartz crystal microbalance (QCM) biosensor technique. The first two papers focused on the synthesis and study of biotin selective polymer films prepared using the molecularly imprinted polymer (MIP) technique. LÄS MER

  7. 5. Exploring the SPR methodology for monitoring of critical attributes in toxicity testing and bioproduction

    Författare :Gunnar Bergström; Carl-Fredrik Mandenius; Bengt Danielsson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Analysis of biological components is central in bioprocess monitoring, process control, product quality control and cell based toxicity assaying. One of these themes that is pursued in this thesis is the use of biosensors for monitoring of molecular markers, exploiting the natural selectivity of biomolecules. LÄS MER
