  1. 1. Perspectives on the Biological Role of Human Prostasomes

    Författare :Lena Carlsson; Outi Hovatta; Uppsala universitet; []
    Nyckelord :Medical sciences; Prostasomes; cryopreservation; human spermatozoa; sperm motility; anti- prostasome antibodies; PC-3 cells; Bacillus megaterium; antibacterial; antisperm antibodies; complement activation; sperm agglutination; infertility; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

    Sammanfattning : Prostasomes are extracellularly occurring organelles which are secreted in human semen by the prostate gland. Prostasomes have several known biological activities, but their physiological function is still unclear. In this thesis some new aspects were studied on the biological role of the prostasomes.

  3. 2. Microbial biopolymer production from waste streams

    Författare :Kasra Khatami Mashhadi; Zeynep Cetecioglu; Anders F. Andersson; Maria Reis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioaugmentation; Burkholderia cepacia; Cupriavidus necator; Mixed microbial cultures; Polyhydroxyalkanoates; Volatile fatty acids; Bioaugmentering; Burkholderia cepacia; Cupriavidus necator; Blandade mikrobiella kulturer; Polyhydroxyalkanoater; Flyktiga fettsyror; Chemical Engineering; Kemiteknik;

    Sammanfattning : Burgeoning concerns on the adverse environmental impacts of fossil-derived products are propelling the pursuit of material production from sustainable resources. Resource recovery from waste is a key component of meeting the environmental sustainability agendas set by the United Nations. LÄS MER

  4. 3. Rhizobacteria associated to Vitis vinifera and their effect on the control of Xiphinema index, Meloidogyne ethiopica and Vitis growth

    Författare :Erwin Aballay; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Plant-parasitic nematodes are one of the most important pests affecting the growth of vineyards due to the destruction of new roots. Several species are associated with this problem, the most important being the ectoparasite Xiphinema index and the endoparasite Meloidogyne ethiopica. LÄS MER

  5. 4. Physiological effects of conditioned medium and passage number on Spodoptera frugiperda Sf9 serum free cultures

    Författare :Ingrid Svensson; Lena Häggström; Mats Martinelle; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Spodoptera frugiperda Sf9; insect cell cultures; conditioned medium; cell cycle phase dynamics; proteolytic activity; antibacterial activity; recombinant protein production; Bioteknik; Bioengineering; Bioteknik;

    Sammanfattning : The aim of this study was to better understand the role of conditioned medium (CM) in Spodoptera frugiperda Sf9 insect cell proliferation and recombinant protein production using the baculovirus expression system. CM was found to stimulate cell proliferation. LÄS MER

  7. 5. Exploring Saccharomyces cerevisiae’s responses to acetic acid and other inhibitors found in lignocellulosic hydrolysates

    Författare :Maurizio Mormino; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; acetic acid biosensor; formic acid; CRISPRi screening; acetic acid; Saccharomyces cerevisiae; lignocellulosic inhibitor tolerance; differential gene expression;

    Sammanfattning : The limited tolerance of the budding yeast Saccharomyces cerevisiae to lignocellulosic hydrolysate inhibitors is a key challenge to its use in biorefinery cell factories. Considerable resources have been invested in the isolation of yeast strains with better tolerance towards the inhibitors released during lignocellulose hydrolysis, such as acetic acid. LÄS MER
