  1. 1. Polyelectrolytes and Polycomplexes in Biotechnology

    Detta är en avhandling från Department of Biotechnology, Center for Chemistry and Chemical Engineering, P.O. Box 124, S-221 00 Lund, Sweden

    Författare :Maria Dainiak; Lunds universitet.; Lund University.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; affinity precipitation; expanded bed adsorption.; Fab fragments; monoclonal antibodies; glyceraldehyde-3-phosphate dehydrogenase; misfolded protein; chaperone; poly N-ethyl-4-vinylpyridinium bromide ; poly methacrylic acid ; poly acrylic acid ; Key words: polyelectrolyte; polyelectrolyte complexes; Biotechnology; Bioteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : Polyelectrolytes and polyelectrolyte complexes (PECs) are characterized by many useful properties that endow them with high potential in different areas of biotechnology. This thesis describes the development and analyses of some new systems and methods utilizing poly(acrylic acid) (PAA), poly(methacrylic acid) (PMA), poly (N-ethyl-4-vinylpyridinium bromide) (PEVP) and PMA-PEVP complexes.

  2. 2. Algal-Bacterial Photobioreactors for the Degradation of Toxic Organic Pollutants

    Detta är en avhandling från Biotechnology (LTH), Lund University

    Författare :Raul Munoz; Lunds universitet.; Lund University.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biotechnology; Bioteknik; symbiosis.; nutrient removal; heavy metals removal; Algal-bacterial systems photobioreactors; toxic organic pollutants;

    Sammanfattning : The aerobic biodegradation of toxic organic volatile contaminants is always limited by the low aqueous solubility of O2. Therefore, intensive bubbling or surface aeration is required to supply the bacterial community with sufficient O2 to carry out pollutant mineralization. This can cause the hazardous volatilization of toxic volatile contaminants. LÄS MER

  3. 3. Asymmetrical Flow Field-Flow Fractionation in the Application to Biological Macromolecules

    Detta är en avhandling från Cecilia Arfvidsson, Department of Technical Analytical Chemistry, Center for Chemistry and Chemical Engineering

    Författare :Cecilia Arfvidsson; Lunds universitet.; Lund University.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; Bioteknik; Biotechnology; biotechnology; recombinant protein production; molecular weight; Escherichia coli; ribosomes; glutenin; asymmetrical flow field-flow fractionation; multiangle light scattering;

    Sammanfattning : Asymmetrical flow field-flow fractionation (AsFlFFF) is especially useful in the application to biological macromolecules due to the absence of a stationary phase in the separation channel. As a result no upper exclusion limit occurs and low shear forces affect the sample components. LÄS MER

  4. 4. Separation of Glycoproteins using Shielding Boronate Affinity Chromatography

    Detta är en avhandling från Biotechnology (LTH)

    Författare :YuCai Li; Lunds universitet.; Lund University.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN; MEDICINE; boronate; affinity chromatography; chymotrypsin; haemoglobin; mistletoe lectin; neoglycoprotein; glycosylation; shielding; Biotechnology; Bioteknik; Pharmaceutical and related technologies; Läkemedelsteknik och relaterad teknik;

    Sammanfattning : Glycoproteins, a class of biomolecules, exhibit a variety of biological activities and therefore are of importance in modern biotechnology and pharmaceutical industry. Pure glycoproteins are needed for structural and functional studies. However, the separation of glycoproteins has been a problem until now due to their structural complexity. LÄS MER

  5. 5. EVALUATION OF BIOLOGICAL STRATEGIES TO ENHANCE HYDROLYSIS DURING ANAEROBIC DIGESTION OF COMPLEX WASTE

    Detta är en avhandling från Biotechnology (LTH)

    Författare :Dores Cirne; Lunds universitet.; Lund University.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; kontroll av utsläpp; Miljöteknik; Biotechnology; bioaugmentation; enzyme addition; Environmental technology; pollution control; FISH; cellulose; inhibition; lipids; Clostridium lundense; hydrolysis; complex substrate; Anaerobic digestion; renewable energy; Bioteknik; LCFA;

    Sammanfattning : Anaerobic digestion (AD) offers considerable potential in the production of energy from renewable sources, and is being increasingly recognised as a sustainable technology for the treatment of waste. The production of energy from waste such as municipal solid waste (MSW), lipid-rich waste, and agricultural biomass and waste may play an important role in the production of renewable energy given the huge amounts of these types of waste generated annually.
