  2. 26. Ethanol from Lignocellulose: Physiological Effects of Inhibitors and Fermentation Strategies

    Author : Mohammad Taherzadeh Esfahani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fermentation; dilute-acid hydrolyzate; ethanol; hydroxymethyl furfural; furfural; acetic acid; lignocellulose; fed-batch; yeast; pantothenate; control; inhibition; HMF;

    Abstract : Fermentative ethanol production from dilute-acid hydrolyzates of wood using the yeast Saccharomyces cerevisiae was investigated. Of known inhibitors in hydrolyzates, acetic acid, furfural and hydroxymethyl furfural (HMF) were found in the highest concentrations (up to about 10 g/l). READ MORE

  4. 27. Ethanol from lignocellulose : physiological effects of inhibitors and fermentation strategies

    Abstract : Fermentative ethanol production from dilute-acid hydrolyzates of wood using the yeast Saccharomyces cerevisiae was investigated. Of known inhibitors in hydrolyzates, acetic acid, furfural and hydroxymethyl furfural (HMF) were found in the highest concentrations (up to about 10 g/l). READ MORE

  5. 28. On Folates in Yeasts -Exploring Yeasts as Vehicles for Biofortification of Folates in Food

    Author : Sofia Hjortmo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; yeast; B vitamin; biofortification; bread; indigenous food; Saccharomyces cerevisiae; folic acid; fermented food; togwa; Folate;

    Abstract : High intake of the B vitamin folate during pregnancy is known to decrease the risk for development of neural tube defects. In addition, a good folate status may prevent the progression of several diseases such as megaloblastic anaemia, cardiovascular disease, cancer and Alzheimer’s disease. READ MORE

  6. 29. Improving flavonoid production in Saccharomyces cerevisiae using synthetic biology tools

    Author : Dany Liu; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metabolic engineering; biosensors; in vivo directed evolution; enzyme scaffolding; yeast;

    Abstract : Flavonoids are plant secondary metabolites and represent one of the largest classes of natural products. Due to their health-beneficial properties, they have found potential applications in foods, beverages, cosmetics, and pharmaceuticals. Currently, their production is based on extraction from plant material. READ MORE

  7. 30. On protein oxidation, lifespan and aging in Saccharomyces cerevisiae

    Author : Hugo Aguilaniu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asymmetric cell division; protein oxidation; yeast; aging; signalling pathways;

    Abstract : In this thesis, we have investigated the physiology of protein oxidation and its possible role in the aging of the yeast Saccharomyces cerevisiae. There are two ways to measure yeast aging. First, they can only divide a finite number of times even when all nutrients necessary for division are provided. This is replicative aging. READ MORE
