  1. 6. CRISPRi/a for investigating yeast tolerance to inhibitors in lignocellulosic hydrolysates

    Författare :Ibai Lenitz Etxaburu; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulosic hydrolysates; ChIP-exo; Screening; Biosensor; Formic acid; Competitive growth assay; Yeast; Tolerance; CRISPRi a; Acetic acid;

    Sammanfattning : Saccharomyces cerevisiae has immense potential as a cell factory in various biotechnological processes where biomass from agricultural industry residues is used as feedstock. Nonetheless, the inhibitors released during the pretreatment of the biomass makes lignocellulosic hydrolysates a challenging substrate for microorganisms. LÄS MER

  3. 7. A Molecular view of inital Atmospheric Corrosion : In situ surface studies of zinc based on vibrational spectroscopy

    Författare :Jonas Hedberg; Christofer Leygraf; Geiger Franz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmospheric corrosion; zinc; vibrational spectroscopy; formic acid; acetic acid; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Atmospheric corrosion takes place on most metals as they interact with thesurrounding environment. A degradation of the metal is the common result,which often leads to a shortened lifespan of the material. LÄS MER

  4. 8. Ethanol from Lignocellulose: Physiological Effects of Inhibitors and Fermentation Strategies

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

    Sammanfattning : 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). LÄS MER
