  3. 2. The potential of industrial hemp (Cannabis sativa L.) for biogas production

    Detta är en avhandling från Biotechnology, Lund University

    Författare :Emma Kreuger; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biogas; anaerobic digestion; bioenergy; Cannabis sativa L.; hemp; energy crops; biofuel; methane; transportation fuel; renewable energy;

    Sammanfattning : Biofuels are currently produced from agricultural crops, and an increasing use of crops for this application is expected in the EU in the years to come. The dominating crops cultivated in the EU for biofuel production today have a relatively large environmental impact. LÄS MER

  4. 3. Homopolysaccharide metabolism in Lactobacillus reuteri and Pediococcus parvulus

    Detta är en avhandling från Applied Microbiology (LTH)

    Författare :Emma Årsköld; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; virology; bacteriology; Carbohydrate metabolism; Exopolysaccharides; Lactic acid bacteria; Mikrobiologi; bakteriologi; virologi; mykologi; mycology; Microbiology;

    Sammanfattning : This thesis deals with the central carbohydrate metabolism and exopolysaccharide (EPS) formation in two different lactic acid bacteria (LAB): Lactobacillus reuteri and Pediococcus parvulus. LAB are traditionally used as starter cultures in the food industry. In general, LAB harbours one glycolytic pathway converting carbohydrates into lactic acid. LÄS MER

  5. 4. Engineering short-chain carboxylic-acid metabolism in the model microorganism Escherichia coli

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Gustav Sjöberg; Antonius J. A. van Maris; Solange Mussatto; [2020]
