1. 1. Polyelectrolytes and Polycomplexes in Biotechnology

   Detta är en avhandling från Department of Biotechnology, Lund University

   Författare :Maria Dainiak; Lunds universitet.; Lund University.; [2001]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; expanded bed adsorption.; affinity precipitation; 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.

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

   Detta är en avhandling från Biotechnology, Lund University

   Författare :Raul Munoz; Lunds universitet.; Lund University.; [2005]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; 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

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

   Detta är en avhandling från Biotechnology, Lund University

   Författare :Dores Cirne; Lunds universitet.; Lund University.; [2006]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; kontroll av utsläpp; 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.

5. 4. Solar-based physicochemical-biological processes for the treatment of toxic and recalcitrant effluents

   Detta är en avhandling från Biotechnology, Lund University

   Författare :Tamer Essam; Lunds universitet.; Lund University.; [2006]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; combined process; biodegradaiton; phenolics; phenol; Advanced Oxidation Processes; Photodegradation; photolysis;

   Sammanfattning : Wastewater treatment is a worldwide necessity that is even more crucial to countries deprived from abundant fresh water sources or unable to afford advanced and costly processes. With this perspective, this thesis was conducted within an Egyptian-Swedish research collaboration that aimed to develop solar-based (as free renewable energy source available locally) process for hazardous wastewater treatment.

   Sammanfattning : 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.
