  1. 1. Polyelectrolytes and Polycomplexes in Biotechnology

    University dissertation from Department of Biotechnology, Lund University

    Author : Maria Dainiak; Lunds universitet.; Lund University.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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;

    Abstract : 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

    University dissertation from Biotechnology, Lund University

    Author : Raul Munoz; Lunds universitet.; Lund University.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Bioteknik; symbiosis.; nutrient removal; heavy metals removal; Algal-bacterial systems photobioreactors; toxic organic pollutants;

    Abstract : 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. READ MORE

  3. 3. Primary Recovery of Biologically Active Compounds Using Macroporous Monolithic Hydrogels

    University dissertation from Biotechnology, Lund University

    Author : Amro Hanora; Lunds universitet.; Lund University.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; macroporous; Downstream processing; Biologically active compounds; Biotechnology; Läkemedelsteknik och relaterad teknik; Pharmaceutical and related technologies; Polymerteknik; biopolymers; Biokemisk teknik; Polymer technology; Makromolekylär kemi; Biochemical technology; Affinity chromatography; Ion exchange chromatography; Expanded bed adsorption chromatography.; Macromolecular chemistry; High through put screening; lactica acids; Endotoxin; Plasmid DNA; Cryogel columns; Bioteknik;

    Abstract : The completion of sequencing of human and other mammalian genomes opens a new era for drug development. New approaches have been proposed for tackling diseases such as development of small molecule therapies based on understanding of human genome and proteome, new proteinous based therapies, where the therapeutic protein can inhibit or modify a certain metabolic pathway or DNA-based therapies delivering a gene into the cell (e.

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

    University dissertation from Biotechnology, Lund University

    Author : Dores Cirne; Lunds universitet.; Lund University.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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;

    Abstract : 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.

  5. 5. Thermostable Xylanases from Rhodothermus marinus

    University dissertation from Biotechnology, Lund University

    Author : Leif Dahlberg; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; application; characterization; xylanolytic bacteria; thermophile; thermostability; purification; thermostable xylanase; xylosidase; Rhodothermus marinus; xylanase; gene sequence; Biotechnology; Bioteknik;

    Abstract : Abstract Hot springs in Iceland can serve as sources of thermophilic, xylanolytic bacteria secreting very thermostable xylanolytic enzymes. The aerobic, thermophilic bacteria Rhodothermus marinus secretes multiple xylanases and xylosidases. One of the xylanases was purified to electrophoretic homogeneity and was characterized. READ MORE
