  1. 1. Probing Control of Glucose Feeding in Escherichia coli Cultivations

    Author : Mats Åkesson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; control engineering; robotics; Automation; dissolved oxygen; acetate; glucose feeding; robotteknik; Escherichia coli; Process control; fed-batch cultivation; reglerteknik; Biotechnology; Bioteknik;

    Abstract : Production of many proteins can today be made using genetically modified organisms. One of the most frequently used host organisms is the bacterium Escherichia coli. A difficulty encountered in cultivations of E. coli is the accumulation of the metabolic by-product acetate which inhibits cell growth and production of a desired protein. READ MORE

  2. 2. Ethanol from woodCellulase enzyme production

    Author : Zsolt Szengyel; Avdelningen för kemiteknik; []
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 3. Bacterial and fungal growth in soil: The effect of temperature and substrate addition

    Author : Stephanie Reischke; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bacterial growth; Fungal growth; Respiration; Carbon loading; Glucose mineralisation; Temperature adaptation; Temperature sensitivity; Temperature dependence;

    Abstract : Bacteria and fungi are the main agents in decomposition of soil organic matter. Their activity is determined by the availability and quality of substrate, especially its content of carbon, but also nitrogen and phosphorus. Other environmental factors, which affect the activity of the microbial community in soil, are temperature, moisture and pH. READ MORE

  4. 4. Accident-tolerant uranium nitride

    Author : Aneta Herman; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; accident-tolerant fuel; uranium nitride; chromium; glucose; internal sol-gel;

    Abstract : After the nuclear accident at Fukushima-Daiichi in 2011, a search for alternatives to a current fuel-clad standard UO2-Zircaloy was encouraged by government and industry and novel fuel-clad systems were selected. These systems are often referred to as Accident Tolerant systems, because of an improved response to severe accidents. READ MORE

  5. 5. Systems-level investigation of the interaction between glucose metabolism and the Snf1/Mig1 signalling pathway

    Author : Niek Welkenhuysen; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; glucose signalling; microfluidics; Saccharomyces cerevisiae;

    Abstract : Saccharomyces cerevisiae Snf1 and its mammalian homolog, AMPK, are members of a protein kinase family present throughout the Eukaryotic kingdom. AMPK plays an essential role in different cellular processes and is involved in diseases such as diabetes, obesity and cancer. READ MORE
