  1. 1. Nanoporous Aluminum Oxide – A Promising Support for Modular Enzyme Reactors

    Författare :Marcus Kjellander; Gunnar Johansson; Gunnar Henriksson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoporous aluminum oxide; immobilized enzymes; bioreactor; Biokemi; Biochemistry;

    Sammanfattning : Nanoporous alumina is a rather newly characterized material that so far has found limited use in the construction of bioreactors. The material has many advantages compared to conventional immobilization matrices. I have investigated its use in flow-through bioreactors. LÄS MER

  3. 2. Understanding the Influence of Wood Extractives on Off-Gassing during Storage of Wood Pellets

    Författare :Workson Siwale; Jonas Berghel; Gunnar Henriksson; Michael Finell; Stefan Frodeson; Gunnar Johansson; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Off-gassing; Carbon Monoxide; Carbon Dioxide; Methane; Self-heating; Additive Oils; Fatty and Resin Acids; Solid Biofuels; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : Wood pellets have become a solid biomass fuel of choice because they are a standardized product with known quality properties. However, the self-heating and off-gassing tendencies during storage of wood pellets threatens the consistency of the pellets’ quality properties. LÄS MER

  4. 3. Biochemical Study and Technical Applications of Fungal Pectinase
