  1. 1. Design and development of a novel textile based bioreactor: : Ethanol and biogas production as case studies

    Författare :Osagie Alex Osadolor; Christian Larroche; Högskolan i Borås; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; bioethanol; biogas; bioreactor; bioreactor design; techno-economic analysis; membrane stress analysis; mass transfer; hydrodynamics; Resource Recovery; Resursåtervinning;

    Sammanfattning : Bioreactors are designed to provide enabling conditions for the controlled growth of microorganisms, such as good heat and mass transfer, aeration, hydrodynamics, geometry for adequate gas holdup, pH and foaming control, conditions for optimal substrate consumption and product formation, as well as mechanisms for monitoring microbial conditions. Additionally, bioreactors are designed to handle stress that would be exerted on them by the weight of the fermenting media and by the high pressure used for sterilisation. LÄS MER

  2. 2. Material development of a textile bioreactor : All-polyamide composite for the construction of bioreactors

    Författare :Mostafa Jabbari; Mikael Hedenqvist; Högskolan i Borås; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; textile bioreactor; biofuel; coated fabric; all-polyamide composite; polyvinyl chloride PVC ; solvent replacement; Hansen solubility parameters HSPs ; Resource Recovery; Resursåtervinning;

    Sammanfattning : Bioreactors are manufactured from stainless/carbon steel, concrete, glass, etc., which are costly and time-consuming to install. Recently, several research studies have been initiated to find cost-efficient materials for constructing bioreactors, one of which is coated textiles. LÄS MER

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

    Författare :Marcus Kjellander; Gunnar Johansson; Gunnar Henriksson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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

  4. 4. Functionalization of Synthetic Polymers for Membrane Bioreactors

    Författare :Hamidreza Barghi; Högskolan i Borås; []

    Sammanfattning : Membrane bioreactors (MBRs) show great promise for productivity improvement and energy conservation in conventional bioprocesses for wastewater reclamation. In order to attain high productivity in a bioprocess, it is crucial to retain the microorganisms in the bioreactors by preventing wash out. LÄS MER

  5. 5. Engineering and Functionalization of Degradable Scaffolds for Medical Implant Applications

    Författare :Yang Sun; Anna Finne-Wistrand; Ann-Christine Albertsson; Minna Kellomäki; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tissue engineering; nanodiamond; scaffold; bioreactor; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The treatment of bone defects is facing the situation of lacking donations for autotransplantation. As a valid approach, scaffold-based tissue engineering combines the construction of well-defined porous scaffolds with advanced cell culturing technology to guide tissue regeneration. LÄS MER
