  1. 1. Insights into the metabolism of Clostridium thermocellum for cellulosic ethanol production

    Författare :Johannes Yayo; Antonius J. A. van Maris; Richard Sparling; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clostridium thermocellum; ethanol; glucose; fructose; amino acids; pyrophosphate; chaotropicity; thermodynamic driving force; laboratory evolution; chemostats; metabolic engineering; Biotechnology; Bioteknologi;

    Sammanfattning : The societal goal of reaching net-zero CO2 emissions requires development of integrated biorefineries to produce biomass-derived fuels and chemicals. For sustainable second-generation bioethanol production, consolidated bioprocessing with the thermophile Clostridium thermocellum is regarded as a promising concept in view of the microorganism’s native ability to efficiently degrade plant cell wall material.

  3. 2. The Role of Hexose Transport on Glycolytic Flux and Glucose Induced Responses in Saccharomyces cerevisiae

    Författare :Karin Elbing; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glucose signaling; metabolic control; Snf1; glycolysis; Mig1; Hexose transport; Yeast; Saccharomyces cerevisiae;

    Sammanfattning : In the yeast Saccharomyces cerevisiae, glucose is primarily fermented rather than respired. Only in cultivation modes such as chemostats or fed-batches, where the external glucose is kept low, a fully respiratory catabolism is observed. LÄS MER

  4. 3. Life strategies for substrate assimilation by freshwater bacterioplankton

    Författare :Monica Ricão Canelhas; Stefan Bertilsson; Jay T. Lennon; Uppsala universitet; []
    Nyckelord :lake; methane; bacteria; substrate; methanotrophs; pulse; chemostat;

    Sammanfattning : The availability of substrates is one of the most important environmental constraints on the diversity and functioning of microorganisms. Substrate quantity and quality as well as the metabolic features of heterotrophic microorganisms determine the efficiency, speed and type of transformation that can occur in nature. LÄS MER

  5. 4. Analysis and engineering of central metabolism in Clostridium thermocellum

    Författare :Teun Kuil; Antonius J. A. van Maris; Ruud Weusthuis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clostridium thermocellum; biofuels; ethanol; atypical glycolysis; pyrophosphate; phosphofructokinase; thermodynamic driving force; redox cofactor balancing; amino acid secretion; chaotropicity; hexose utilization; laboratory evolution; metabolic engineering; Biotechnology; Bioteknologi;

    Sammanfattning : To mitigate climate change, greenhouse gas emissions must be reduced to net-zero in 2050 requiring a drastic transition in today´s energy sector. To achieve this goal, the use of biofuels produced from lignocellulosic feedstocks, including agricultural and forestry residues, is expected to play an important role. LÄS MER

  7. 5. Acid Tolerance of Streptococcus Mutans Biofilms

    Författare :Jessica Neilands; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acid tolerance; Streptococcus mutans; Biofilms; Acid stress; Fluoride;

    Sammanfattning : Mikrobiologisk forskning har till stor del bedrivits genom att man odlat bakterier i näringslösningar och på agarplattor och sedan studera bakterierna på olika sätt. Detta sätt att odla bakterier överensstämmer inte särskilt bra med hur bakterier växer i verkligenheten. LÄS MER
