  1. 11. The Filzig protein affects embryonic cuticle and taenidia organization in Drosophila

    Magister-uppsats, Institutionen för vård och natur

    Författare :Mengistu Tadese Geberemedhin; [2011]
    Nyckelord :apica extracellular matrix; transmembrane proteins; cuticle; taenidia; chitin;

    Sammanfattning : Abstract The surface of multicellular organisms is covered with epithelial cells that provide a barrier to the external environment. As part of this barrier function, most epithelia produce apical extracellular matrices (aECMs). LÄS MER

  3. 12. Composition and Application Potentials of Scandinavian Tunicates

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Masoumeh Hassanzadeh; [2011]
    Nyckelord :Tunicate; Ciona intestinalis; Clavelina lepadiformis; Cellulose whiskers; biofuel;

    Sammanfattning : Marine ecosystems can be a promising reservoir of various kinds of chemical components, applicable as pharmaceutical materials, food, cosmetics, nutraceuticals, and others for different industry. As an example, Tunicates, a group of marine animals, have been attracted a lot of attention in medical application, food market, water pollution issues, and Cellulose nanomaterial production due to their consisting of chemical compounds such as cellulose, amino-sugars, and proteins or protein-polysaccharide complexes e.

  5. 14. Extraction of chitosan from Fungal cell wall by Sulfuric acid Studying the effect of Deacetylation degree and temperature on recovery chitosan

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Mehdi Gholizadeh Aghdam; [2010]
    Nyckelord :r.pulusilus; m.indicus; extraction; recovery; chitosan; fungal cell wall; sulfuric acid; deacetylation degree; temperature;

    Sammanfattning : The goal of this project is extraction of chitosan optimally by surveys of temperature changesalong with 1% Sulfuric acid utilization. Microbial chitosan is isolated as a bio-componentfrom cell wall of two kinds of Zygomycetes by some extraction methods. This projectcompares ability of two type Fungi (R. pulusilus and M. LÄS MER

  7. 15. Production of ethanol and biomass from orange peel waste by Mucor indicus

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Päivi Ylitervo; [2009]
    Nyckelord :orange peel waste; mucor indicus; ethanol; chitosan; acid hydrolysis; enzymatic hydrolysis;

    Sammanfattning : For the citrus processing industry the disposal of fresh peels has become a major concern for manyfactories. Orange peels are the major solid by-product. Dried orange peels have a high content ofpectin, cellulose and hemicellulose, which make it suitable as fermentation substrate when hydrolyzed. LÄS MER
