  1. 1. Nucleic acid analysis tools Novel technologies and biomedical applications

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Iván Hernández-Neuta; Mats Nilsson; Frank Bier; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nucleic acid analysis; padlock probes; selector probes; rolling circle amplification; microfluidics; single-molecule detection; digital quantification; fluorescence microscopy; mobile phone microscopy; molecular diagnostics; virology; biokemi; Biochemistry;

    Sammanfattning : Nucleic acids are fundamental molecules of living organisms functioning essentially as the molecular information carriers of life. From how an organism is built to how it responds to external conditions, all of it, can be found in the form of nucleic acid sequences inside every single cell of every life form on earth. LÄS MER

  2. 2. Wild plants can improve their rhizosphere chemistry in acid soils

    Detta är en avhandling från Plant Ecology, Ecology Building, SE-223 62 Lund

    Författare :Marion Schöttelndreier; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; wild plants.; time pattern; soil heterogeneity; rhizotrons; rhizosphere; pH; oxalic acid; nutrient availability; malic acid; hydroponics; citric acid; 14C; biodegradation; acid soils; aluminium toxicity; Soil Science; agricultural hydrology; Lantbrukshydrologi; marklära; Plant biochemistry; Växtbiokemi;

    Sammanfattning : Growth conditions on acid soils may be hampered by low nutrient availability and phytotoxic Al (aluminium) concentrations. In this thesis I present my studies on adaptation mechanisms of wild plants to acid soils in the close root environment, the rhizosphere. LÄS MER

  3. 3. Protein isolation from herring (Clupea harengus) using the pH-shift process - Protein yield, protein isolate quality and removal of food contaminants

    Detta är en avhandling från Plant Ecology, Ecology Building, SE-223 62 Lund

    Författare :Sofia Marmon; [2012]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; precipitation; acid; gelation; in vitro digestion; solubilization; herring; protein; salt solubility; pH; lipids; alkaline; transmission electron microscopy; dioxins;

    Sammanfattning : Herring (Clupea harengus) contain valuable proteins but is difficult to process into high-quality foods due to its small size and high content of bones, heme-proteins and lipids. Herring is among the most abundant fish species in the world, but is currently utilized largely for fish meal and oil production. LÄS MER

  4. 4. Evaluation of Pretreatment and Process Configurations for Combined Ethanol and Biogas Production from Lignocellulosic Biomass

    Detta är en avhandling från Chemical Engineering, Lund University

    Författare :Pia-Maria Bondesson; [2016-10-19]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ethanol; biogas; lignocellulose; steam pretreatment; acid catalyst; acetic acid; phosphoric acid; sulphuric acid; xylose fermentation; co-fermentation; process design; SSCF;

    Sammanfattning : In view of global climate change and the increasing energy demand there is a need for renewable energy resources. This thesis discusses an energy-driven biorefinery concept based on the agricultural residues corn stover and wheat straw. The work is divided into two main parts. LÄS MER

  5. 5. Acid Tolerance of Streptococcus mutans Biofilms

    Detta är en avhandling från Malmö University
