  1. 1. Improving the Response of Saccharomyces cerevisiae to Lignocellulosic Hydrolysate Inhibitors in Ethanolic Fermentation

    Författare :Joao Almeida; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; furfural; ethanol; fermentation; phenolics; furaldehyde; HMF; ADH1; xylose reductase; tolerance; Saccharomyces cerevisiae; Lignocellulosic hydrolysate inhibitors; ADH6;

    Sammanfattning : The production of ethanol based on lignocellulosic biomass requires the fermentation of a hydrolysate containing hexose and pentose sugars in an inhibitory environment. In fact, the lignocellulosic hydrolysate obtained from pretreatment and hydrolysis of the raw material contains a variety of inhibitory compounds, including (i) the furaldehydes 5-hydroxymethyl-2-furaldehyde (HMF) and 2-furaldehyde (furfural), (ii) weak acids (e.

  3. 2. Identification and characterization of novel mammalian alcohol dehydrogenases

    Författare :Patrik Strömberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The vertebrate medium chain alcohol dehydrogenases are dimeric zinc metalloenzymes that catalyze the reversible oxidation/reduction of alcohols/aldehydes using NAD+/NADH as coenzyme. In mammals, six classes of ADH have been defined (ADH1-ADH6) whereof five have been identified in humans. LÄS MER

  4. 3. Monitoring of Cellular Dynamics with Focus on Electrochemical Detection Techniques

    Författare :Arto Heiskanen; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microfluidic system; Microchip; PC12; Saccharomyces cerevisiae; Electrochemical impedance spectroscopy; Cell adhesion; Amperometry; Exocytosis; Redox environment; Cell-based assay;

    Sammanfattning : This thesis presents work in two main areas of focus, the development of electroanalytical techniques to monitor the dynamics of cellular processes as well as design and fabrication of microelectrode chips for electrochemical detection as well as a prototype microfluidic system to be used for cell analysis and culturing. The electrochemically monitored cellular parameters were the cellular redox environment (CRE), cell adhesion and exocytosis. LÄS MER

  5. 4. Efficient Conversion of Lignocellulose Hydrolysates- Yeast Tolerance and Redox Metabolism

    Författare :Tobias Modig; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metabolism; Biokemi; metabolism; hyperosmotic stress; Biochemistry; S. cerevisiae; anaerobic growth; inhibitor tolerance; furfural; lignocellulose; HMF; Biotechnology; Bioteknik;

    Sammanfattning : The fermentation of lignocellulose hydrolysates by Saccharomyces cerevisiae for ethanol production was investigated. An important problem for the successful conversion of these hydrolysates is that they often are inhibitory. LÄS MER

  7. 5. Improving Ethanol Production from Lignocellulose Hydrolyzates: Fed-batch Fermentation, Yeast Cultivation and Strain Development for Increased Tolerance

    Författare :Anneli Petersson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Saccharomyces cerevisiae; fed-batch control; Ethanol production; dilute acid hydrolyzate;

    Sammanfattning : Ethanol production by the yeast Saccharomyces cerevisiae from dilute acid lignocellulose hydrolyzate was studied with the aim to improve fuel ethanol production. Specifically, the problem of inhibition was addressed. LÄS MER
