  1. 1. Continuous Ethanol Production from Dilute-acid Hydrolyzates: Detoxification and Fermentation Strategy

    Författare :Ronny Purwadi; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HMF; serial bioreactor; immobilization; overliming; furfural; ethanol; continuous cultivation; S. cerevisiae; flocculating yeast; continuous detoxification; dilute-acid hydrolyzate;

    Sammanfattning : The production of fuel ethanol from cellulosic biomass is of growing interest around the world. Lignocellulosic residuals can be used to produce transportation fuel, with the overall process having little net production of greenhouse gases. LÄS MER

  3. 2. Ethanol Production from Lignocellulosic Materials: Potential of Continuous Cultivation, Immobilisation, and Zygomycetous Fungi

    Författare :Ria Millati; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; continuous cultivation; galactose; Rhizopus; xylose; Rhizomucor; S cerevisiae; Mucor; M indicus; glucose; immobilisation; detoxification; arabinose; mannose; overliming; ethanol; dilute-acid hydrolysate;

    Sammanfattning : This thesis deals with the production of bio-ethanol, a sustainable alternative to fossil fuels, from dilute-acid lignocellulosic hydrolysate in a continuous immobilised cell system and fermentation of the hydrolysate by a zygomycete organism, M. indicus. LÄS MER

  4. 3. Overliming and continuous cultivation of dilute-acid hydrolyzates by immobilized Baker's yeast, S. cerevisiae

  5. 4. Influence of strain, feed profile and cultivation technique on the lipid structure and membrane function in Escherichia coli

    Författare :Atefeh Shokri; KTH; []
    Nyckelord :Escherichia coli; phospholipid and fatty acid regulation. fed-batch; continuous cultivation; leakage; protein transport;

    Sammanfattning : The phospholipid and fatty acids content of the Escherichiacoli membrane were investigated during changes of feed rate,cultivation technique and host strains.During continuous cultivation it was shown that the leakageof periplasmic protein to the medium had an optimum at 0.3 h-1,resulting in transport of 20% of the total recombinant product.

  7. 5. 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
