  1. 1. Polymer Displacement and Supermacroporous Cryogels - Two New Tools in Chromatographic Separation of Biomolecules and Bioparticles

    Författare :Pär Arvidsson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biopolymers; Polymerteknik; Biochemical technology; Polymer technology; IMAC; dye-affinity; affinity chromatography; viable cells; cell chromatography; non-clarified cell homogenate; cryogel; Polymer displacement; supermacroporous; Biokemisk teknik;

    Sammanfattning : Production of protein is often accompanied with difficulties due to the large amounts of different biological material resulting from fermentation. This makes purification necessary and affinity chromatography is usually involved as being biospecific, although suffering from limitations as low recovery due to ineffective elution and inability to handle particulate materials.

  3. 2. Sampling, sample treatment, assay and real time monitoring of biotechnological processes using an integrated flow-injection system

    Författare :Mohammad Mazlomi; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioprocess; Sampling; Sample treatment; On-line monitoring; Real time monitoring; Flow injection; Immunoassay; Fermentation;

    Sammanfattning : Microorganisms can be used for production of pharmaceutical substances. With the introduction of gene technology, it is possible to transfer information from one organism to the other, thereby making the receiving organism capable of producing substances that it did not so before. This development is very important for e.g. LÄS MER

  4. 3. CALIBRATION OF CHROMATOGRAPHY MODELS

    Författare :Patrik Persson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; film mass transfer resistance; Kemiteknik och kemisk teknologi; sorption kinetics; external volume; monolithic bed; shallow bed; packed bed; capillary model; detailed model; computer simulation; parameter estimation; diffusion; model calibration; Chromatography; modelling; proteins; Chemical technology and engineering;

    Sammanfattning : AbstractThis thesis is devoted to calibration of mathematical chromatography models. Chromatography models include unknown parameters that must be determined before the models can be applied to optimization or scale-up of a chromatography process. LÄS MER

  5. 4. Production, Purification and Characterization of Antimicrobial Biomolecules from Potential Probiotic Lactic Acid Bacteria

    Författare :Sahar Deraz; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactobacillus; Bioteknik; Biotechnology; Livsmedelsteknik; Food and drink technology; bacteriocin purification.; inhibitory activity; Bacteriocin; antimicrobial protein;

    Sammanfattning : Development and optimization of the production of lactic acid bacteria (LAB) and their attendant 'natural' inhibitors as biopreservatives to control undesirable bacteria currently remains a primary focus of several laboratories involved in research concerning food safety and quality. Strategies utilized to study incorporation of biopreservatives into food include either direct use of LAB-strains or use of a biopreservative preparation in the form of previously fermented product or use of semipurified, purified, or chemically synthesized bacteriocins.

  7. 5. Bacteriophages and cryogels: A new efficient tool in bioseparation

    Författare :Wim Noppe; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biopanning; Cryogel; Phage Display Technology; Chromato-panning;

    Sammanfattning : Abstract Due to developments in the last decades in the field of protein production, new technologies for bio-separation have evolved. Especially in the field of affinity chromatography, the search for new ligands is of great interest. Besides the antibodies used as affinity ligands, synthetic ligands were introduced. LÄS MER
