  1. 21. Bacterial Terminal Oxidases. Studies in Bacillus subtilis

    Författare :Lena Winstedt; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mycology; virology; mykologi; bakteriologi; Mikrobiologi; bacteriology; Microbiology; di-copper center; cytochrome oxidase; Enterococcus faecalis; cytochrome bd; Bacillus subtilis; terminal oxidase; virologi;

    Sammanfattning : The final step in aerobic respiratory pathways is catalyzed by terminal oxidases. Bacteria generally have two or more terminal oxidases. Aerobically grown Bacillus subtilis synthesize three terminal oxidases: one cytochrome c oxidase, cytochrome caa3 and two quinol oxidases, cytochrome aa3 and cytochrome bd. LÄS MER

  3. 22. From Sequence to Structure- Characterizing Human and Plant Aquaporins

    Författare :Kristina Nordén; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Aquaporins constitute a class of membrane proteins that create pores through the lipid bilayer of biological membranes, facilitating the passage of water and other small solutes. Nearly all living organisms possess a more or less intricate set up of aquaporin proteins and the importance of these channels has been implicated in many aspects of health and disease. LÄS MER

  4. 23. Organic Materials-based Electrochemical Flow Cells for Energy Applications

    Författare :Penghui Ding; Reverant Crispin; Viktor Gueskine; Mikhail Vagin; Brian Seger; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : To meet the 2015 Paris Agreement requirement of limiting global warming to 1.5 °C, the transition from fossil fuels to renewables (solar and wind) necessitates a rapid change of the energy landscape. LÄS MER

  5. 24. Plant Membrane Proteomics - using isolated membranes and proteins to compare and quantify subproteomes

    Författare :Katja Bernfur; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; quantification; proteomics; metabolic labeling; plasma membrane;

    Sammanfattning : Membrane proteins are particularly important to characterize, since they are involved in cellular processes of utmost importance in control and regulation of cells, such as transport across membranes, signal transduction and photosynthesis. The word "proteome" means all proteins expressed by a e.g. LÄS MER

  7. 25. Valorization of Kraft Lignin by Fractionation and Chemical Modifications for Different Applications

    Författare :Selda Aminzadeh; Mikael Lindström; Hasan Jameel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignin Valorization- LignoBoost Lignin-Clean Flow Black Lignin- Characterization-Chemical modifications-Fractionation-applications; Chemical Engineering; Kemiteknik;

    Sammanfattning : AbstractLignin is one of the most abundant biopolymers. Approximately 70 million tons of technical lignin is generated annually, but only little is used for products other than energy. The complexity of lignin hinders full utilization in high-value products and materials. LÄS MER
