  1. 11. Characterization of respiratory physiology in Lactococcus lactis for high-yield production of high-performance starter cultures

    Författare :Anna Johanson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; batch cultivations; lag phase; haemin haem; respiration-permissive conditions; aerobic growth; Lactic acid bacteria; acidification activity; continuous cultivations; starter culture production;

    Sammanfattning : Fermented food products are consumed world-wide, every day, and the demand is growing as intake increases. Lactococcus lactis is a lactic acid bacterium commonly used as a starter culture to produce fermented dairy products. LÄS MER

  3. 12. Hydrogen Production by Caldicellulosiruptor species: The Organism and the Metabolism

    Författare :Ahmad Zeidan; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Extreme thermophile; Caldicellulosiruptor; Biohydrogen; Co-culture; Coexistence; Hydrogen tolerance; Genome-scale reconstruction; In silico; Flux balance analysis;

    Sammanfattning : Hydrogen holds a great promise as an efficient and clean future energy carrier due to its high energy density and lack of pollutant generation. Anaerobic degradation of organic substrates by heterotrophic microorganisms enables the production of hydrogen from a wide spectrum of agricultural feedstock and waste products. LÄS MER

  4. 13. Genetic engineering of Yarrowia lipolytica for the sustainable production of food oils

    Författare :Oliver Konzock; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; triacyclglycerols; RNA-seq; tolerance; cocoa butter; hydrolysate; yeast; desaturase; filamentation;

    Sammanfattning : The human population and its demand for food oils is constantly growing. However, increasing food oil production currently requires the deforestation of mostly tropical rainforests to allow the plantation of oil crops. LÄS MER

  5. 14. Possibilities to use industrial oxidic by-products as neutralising agent in bioleaching and the effect of chloride on biooxidation

    Författare :Chandra Sekhar Gahan; S. Subramanian; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : The cost for neutralisation is the second largest cost in a bioleaching operation for which, possibilities to replace generally used lime/limestone was tested. Industrial oxidic by-products generated form Swedish industries were investigated for neutralising capacities by chemical leaching with sulphuric acid at pH 1. LÄS MER

  7. 15. Systems Biology of Yeast Lipid Metabolism

    Författare :Pramote Chumnanpuen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Transcriptome; Integrated analysis; Lipidome.; Inositol-choline; Opi1; Yeast lipid metabolism; high throughput techniques; Ino4; TORC1; Snf1; Ino2;

    Sammanfattning : Lipid metabolism plays an important role in the development of many different life-style related diseases, such as type 2 diabetes and atherosclerosis, and understanding the molecular mechanisms behind regulation of lipid biosynthesis and degradation may lead to development of new therapies. In this project we undertook a global study of lipid metabolism in the eukaryotic model organism Saccharomyces cerevisiae. LÄS MER
