    Sammanfattning : Better utilization of renewable sources of energy and recovery of resources from waste streams are important challenges for researchers. Bioelectrochemical systems (BESs) are new technologies which e.g. could be used to produce green energy from waste sources or store renewable electricity as chemical fuels. LÄS MER

  2. 2. Enzyme Immobilization in Mesoporous Silica

    Sammanfattning : Catalysts are widely used in many industries for production of chemicals, pharmaceuticals, fuels and energy. There is a need for more sustainable production processes, with reduced energy and raw material consumption together with a reduction in waste and toxic by-products. LÄS MER

  3. 3. Multidimensional engineering for the production of fatty acid derivatives in Saccharomyces cerevisiae

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Yating Hu; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metabolic engineering; fatty acid derivatives; protein engineering; Saccharomyces cerevisiae; tolerance; transporter;

    Sammanfattning : Saccharomyces cerevisiae , also known as budding yeast, has been important for human society since ancient time due to its use during bread making and beer brewing, but it has also made important contribution to scientific studies as model eukaryote. The ease of genetic modification and the robustness and tolerance towards harsh conditions have established yeast as one of the most popular chassis in industrial-scale production of various compounds.

  4. 4. Sanitisation of faecal sludge by ammonia

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Jörgen Fidjeland; Sveriges lantbruksuniversitet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Faecal sludge contains valuable plant nutrients and can be used as a fertiliser in agriculture, instead of being emitted as a pollutant. As this involves a risk of pathogen transmission, it is crucial to inactivate the pathogens in faecal sludge. One treatment alternative is ammonia sanitisation, as uncharged ammonia (NH₃) inactivates pathogens. LÄS MER

  5. 5. Ethanol from woodCellulase enzyme production

    Detta är en avhandling från Department of Chemical Engineering, Lund University

    Författare :Zsolt Szengyel; Lunds universitet.; Lund University.; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; FPA measurement; acetic acid; furfural; non-volatile; volatile; inhibition; pH; carbon source; liquid; solid; softwood; hardwood; cellulases; production; Kemiteknik och kemisk teknologi; Biotechnology; Bioteknik;

    Sammanfattning : Conversion of biomass to liquid fuels, such as ethanol, has been investigated during the past decades. First due to the oil crisis of the 1970s and lately because of concerns about greenhouse effect, ethanol has been found to be a suitable substitute for gasoline in transportation. LÄS MER
