  1. 1. Cell cycle analysis of archaea

    Författare :Andrzej Poplawski; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; mikrobiologi; Microbiology;

    Sammanfattning : In my thesis, the cell cycle analysis of archaea and hyperthermophilic organisms is presented for the first time. Crenarchaea from the genus Sulfolobus were used as a model system. Plow cytometry and light microscopy were applied to investigate the timing and coordination of different cell cycle events. LÄS MER

  3. 2. Studies on endoribonuclease RNase E and its role in RNA turnover

    Författare :Björn Sohlberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Gene regulation RNA processing mRNA stability endoribonucleases RNase E AUUUA-motifs Archaea;

    Sammanfattning : RNA turnover is an important level of regulation of gene expression, by which a cell can rapidly adjust to changes in its environment. The turnover of RNA is done by an efficient but not well understood mechanism. LÄS MER

  4. 3. Poly (3-hydroxybutyrate) from a moderate halophile: production and modification for new applications

    Författare :Marlene Munoz; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biopolymers; polyhydroxyalkanoates; polyhydroxybutyrate; moderate halophile; Halomonas boliviensis; fermentation; recovery; thermally induced phase separation; scaffolds; covalent modification; hydrophobic ion pairing; polyethylenemine; lysozyme.;

    Sammanfattning : Polyhydroxybutyrate (PHB) is a homopolymer belonging to the family of biopolyesters, polyhydroxyalkanoates (PHA) produced by different bacteria and archaea as intracellular granules often under conditions of metabolic stress due to a limited supply of essential nutrients. The properties of the PHAs are similar to those of polyethylene and polypropylene and can hence replace these fossil based polymers in a large variety of applications. LÄS MER

  5. 4. Exploration of microbial diversity and evolution through cultivation independent phylogenomics

    Författare :Joran Martijn; Thijs J.G. Ettema; Andrew Roger; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cultivation independent genomics; metagenomics; single-cell genomics; metagenomic binning; phylogenetics; phylogenomics; phylogenetic artefacts; comparative genomics; gene tree-species tree reconciliation; rRNA amplicon sequencing; Tara Oceans; origin of mitochondria; Alphaproteobacteria; Rickettsiales; Haloarchaea; endosymbiosis; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Our understanding of microbial evolution is largely dependent on available genomic data of diverse organisms. Yet, genome-sequencing efforts have mostly ignored the diverse uncultivable majority in favor of cultivable and sociologically relevant organisms. LÄS MER
