  1. 16. Tools and applications to assess yeast physiology and robustness in bioprocesses: Lab-scale methods from single cells to populations

    Författare :Luca Torello Pianale; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scale-up; fluorescence; scale-down; Saccharomyces cerevisiae; biosensors; microfluidics; bioproduction;

    Sammanfattning : Bioprocesses enable the efficient production of valuable chemicals by microorganisms such as the yeast Saccharomyces cerevisiae . Predictable and stochastic perturbations affect microbial performance in an industrial-scale bioreactor. LÄS MER

  3. 17. Effects of high sugar concentrations in production scale bioreactor : a scale-down study of s. cervisiae

    Författare :Stefan George; KTH; []
    Nyckelord :;

    Sammanfattning : Substrate concentration gradients exist in large-scalebioreactors, due to a combination of insufficient mass transferand mixing, and microbial activities. Zones with high substrateconcentration may arise close to a feed point. It is largelyunknown to what extent these gradients influence themicroorganisms and what the microbial response might be.

  4. 18. Bio-based barriers from wood hydrolysates : A pilot-scale approach

    Författare :Soheil Saadatmand; Ulrica Edlund; Youssef Habibi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood hydrolysate; biorefinery; oxygen permeability; multilayer barriers; food packaging.; vedhydrolysat; syrgaspermeabilitet; barriärskikt; livsmedelsförpackning;

    Sammanfattning : Wood hydrolysates (WHs) are liquids extracted from the hydrothermal treatment of wood. They exist as the byproduct of forestry industries such as the dissolving pulp and fiberboard industries. WHs are hemicellulose-based with a large share of lignin in the chemical composition.

  5. 19. Small-Scale Fisheries Governance : Broadening Perspectives on Markets, Relationships and Benefits in Seafood Trade

    Författare :Elizabeth Drury O'Neill; Beatrice Crona; Maricela de la Torre Castro; Stockholms universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sustainability; Social-Ecological System; Value chain approach; Social realm; Gender Roles; Local attributes; Marine ecosystem; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : This licentiate adresses the relative ambiguity surounding benefit flows from small-scale fisheries seafood trade with a specific focus on how they may be impacted by market and social stuctures. Small-scale fishery governenace has previously taken a narrowly approach to sustainability. LÄS MER
