  1. 16. Evaluation of precursor and cofactor engineering strategies influencing fatty acid metabolism in Saccharomyces cerevisiae

    Författare :Alexandra Linda Bergman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; metabolic engineering; fatty acids; oleochemicals; NADPH; Sustainability; phosphoketolase; acetyl-CoA; transcription factor;

    Sammanfattning : If humanity is to reduce the rate of climate change, it is essential that our societies switch to a more sustainable production of fuels and chemicals, which in turn depends on technological development. Oleochemical production via microbial catalysts – such as the yeast Saccharomyces cerevisiae – can use a considerably broader range of renewable substrates compared to the conventional production processes.

  3. 17. Lipid production from lignocellulosic material by oleaginous yeasts

    Författare :Jule Brandenburg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Oleaginous yeasts are a potential lipid source for production of fuels, chemicals and food or feed and use of lignocellulosic biomass as feedstock is considered a sustainable approach. Pre-treatment of lignocellulose is required to release the major carbon sources, glucose, xylose and other sugars for lipid production by oleaginous yeasts, but also releases inhibitory compounds.

  4. 18. Understanding and improving microbial cell factories through Large Scale Data-approaches

    Författare :Daniel Brink; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microbiology; lignocellulose; lignin; D-xylose; Saccharomyces cerevisiae; Pseudomonas putida; bioinformatics; genome assembly; flow cytometry; metabolic engineering; sugar sensing signalling;

    Sammanfattning : Since the advent of high-throughput genome sequencing methods in the mid-2000s, molecular biology has rapidly transitioned towards data-intensive science. Recent technological developments have increased the accessibility of omics experiments by decreasing the cost, while the concurrent design of new algorithms have improved the computational work-flow needed to analyse the large datasets generated.

  5. 19. Combined production of edible mushrooms and biofuels from lignocellulosic residues

    Författare :Feng Chen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Forest residues, wood-processing by-products and other lignocellulosic materials are promising renewable resources for bioconversion to advanced biofuels such as cellulosic ethanol. Increased production of biofuels from lignocellulosic materials would allow reducing environmental problems caused by the use of fossil resources while supporting development of bioeconomy. LÄS MER

  7. 20. Decision-making and decision support connected to biogas use in Sweden

    Författare :Sofia Dahlgren; Stefan Anderberg; Thomas Magnusson; Jonas Ammenberg; Iva Ridjan Skov; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Human activities cause many sustainability challenges in the world, which need to be dealt with. One way to decrease the negative impacts related to those challenges is by replacing currently dominating technologies with better, alternative technologies. LÄS MER
