  1. 1. Industrial Networks : Purposes and Configurations in the Circular Economy

    Författare :Daniel Berlin; Andreas Feldmann; Cali Nuur; Arni Haldorsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability; Circular Economy; Circular Supply Chain; Supply Chain Management; Industrial Networks; Hållbarhet; Cirkulär ekonomi; Cirkulära försörjningskedjor; Supply chain management; Industriella nätverk; Industrial Economics and Management; Industriell ekonomi och organisation;

    Sammanfattning : Today, it is common knowledge that mitigation of and adaptation to climate change, biodiversity loss, and pollution require sustainability transitions. An essential sustainability transition, for mitigating and adapting to resource depletion, is the shift from unsustainable to sustainable production and consumption patterns. LÄS MER

  3. 2. Short-term adaptation of S. cerevisiae to lignocellulosic inhibitors: Underlying metabolic and physiological changes

    Författare :Marlous van Dijk; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignocellulosic inhibitor tolerance; second generation bioethanol; short-term adaptation; differential gene expression; industrial yeast strains;

    Sammanfattning : The limited tolerance of Saccharomyces cerevisiae (budding yeast) to inhibitors present in lignocellulosic hydrolysates is a major challenge in second-generation bioethanol production. Short-term adaptation of the yeast to lignocellulosic hydrolysates during cell propagation has been shown to improve its tolerance, and thus its performance in lignocellulose fermentation. LÄS MER

  4. 3. Dynamic Adaptation in Industrial IoT Systems

    Författare :An Ngoc Lam; Jerker Delsing; Øystein Haugen; Hartwig Baumgärtel; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomic Computing; Industrial IoT; Self-adaptation; Semantic Interoperability; System of Systems; Cyberfysiska system; Cyber-Physical Systems;

    Sammanfattning : The evolution of the current technological landscape has opened an emergent paradigm that enables interoperability between the digital and physical world, leading to a new generation of industrial systems. This new digitalization era marks the beginning of the fourth industrial revolution, usually referred to as "Industry 4.0". LÄS MER

  5. 4. Physiology of Saccharomyces cerevisiae Producing Recombinant Insulin in Continuous Culture

    Författare :Ali Kazemi Seresht; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; unfolded protein response; Keywords: heterologous protein production; prolonged chemostat; transcriptome; insulin analogue precursor; metabolic adaptation; URA3d; plasmid copy number; promoter truncation; high cell density cultivation; TPI1;

    Sammanfattning : The yeast Saccharomyces cerevisiae has widely been used as a host for the production of heterologous proteins. High-level production of heterologous proteins is likely to impose a metabolic burden on the host cell and can thus affect various aspects of cellular physiology. LÄS MER

  7. 5. Industrial challenges in the use of Saccharomyces cerevisiae for ethanolic fermentation of lignocellulosic biomass

    Författare :Violeta Sanchez Nogue; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; Pentose fermentation; Evolutionary engineering; Acetic acid; pH; Short-term adaptation; Resident yeast; Spent sulphite liquor fermentation; Dekkera bruxellensis; Lactobacillus pentosus.;

    Sammanfattning : The sustainable production of ethanol from lignocellulosic biomass requires the combination of efficient hydrolysis and complete fermentation of all the monomeric sugars present in the raw material. The present work was aimed at tackling some of the major challenges that will be encountered in commercial-scale ethanol production using Baker’s yeast, Saccharomyces cerevisiae, the preferred microorganism for the fermentation step.
