  2. 16. Ethanol production by recombinant and natural xylose-utilising yeasts

    Author : Anna Eliasson; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignocellulose; electron transport; redox balance; Pichia stipitis; Saccharomyces cerevisiae; ethanol; xylose; physiology; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : The xylose-fermenting capacity of recombinant Saccharomyces cerevisiae carrying XYL1 and XYL2 from Pichia stipitis, which encode xylose reductase (XR) and xylitol dehydrogenase (XDH), respectively, is poor due to high xylitol formation. Whereas, P. READ MORE

  4. 17. Physiological Engineering of Xylose Utilisation by Recombinant Saccharomyces cerevisiae

    Author : Nina Quednau Meinander; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein burden; physiology; fed-batch fermentation; chemostat; recombinant Saccharomyces cerevisiae; ethanol; xylose; xylitol; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Xylitol production by recombinant, XYL1-expressing Saccharomyces cerevisiae was investigated in fed-batch fermentation using different cosubstrates for growth, and generation of reduced cofactors and maintenance energy. Xylose was converted into xylitol with 1:1 yield. READ MORE

  5. 18. Maxillofacial cone beam computed tomography (CBCT) : aspetcs on optimisation

    Author : Ayman Al-Okshi; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CBCT; OPTIMISATION; DOSAGE;

    Abstract : Inom odontologisk såväl som inom medicinsk radiologi sker en snabb utveckling av nya tekniker. Nya metoder för att kunna diagnosticera och följa sjukdomsförlopp över tid introduceras. Cone-Beam Computed Tomography (CBCT) är en sådan ny teknik, som introducerades inom odontologin under sent 1990-tal. READ MORE

  6. 19. Improving the Response of Saccharomyces cerevisiae to Lignocellulosic Hydrolysate Inhibitors in Ethanolic Fermentation

    Author : Joao Almeida; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; furfural; ethanol; fermentation; phenolics; furaldehyde; HMF; ADH1; xylose reductase; tolerance; Saccharomyces cerevisiae; Lignocellulosic hydrolysate inhibitors; ADH6;

    Abstract : The production of ethanol based on lignocellulosic biomass requires the fermentation of a hydrolysate containing hexose and pentose sugars in an inhibitory environment. In fact, the lignocellulosic hydrolysate obtained from pretreatment and hydrolysis of the raw material contains a variety of inhibitory compounds, including (i) the furaldehydes 5-hydroxymethyl-2-furaldehyde (HMF) and 2-furaldehyde (furfural), (ii) weak acids (e.

  7. 20. Assembling the Historic Environment: Heritage in the Digital Making

    Author : William Illsley; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; historic environment; critical heritage studies; authorised heritage; heritage politics; digitality;

    Abstract : The historic environment is a formulation of the cultural past as experienced and documented in space. Traditional approaches to the historic environment tend to favour conservational and preservational paradigms, such as heritage stewardship or the dynamics of cultural resource management in relation to national policies.
