  1. 1. Inferring Ancestry Mitochondrial Origins and Other Deep Branches in the Eukaryote Tree of Life

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ding He; Sandra Baldauf; Siv Andersson; Andrew Roger; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular Phylogeny; Phylogenomics; Mitochondria; Eukaryote tree of life; Biology with specialization in Systematics; Biologi med inriktning mot systematik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : There are ~12 supergroups of complex-celled organisms (eukaryotes), but relationships among them (including the root) remain elusive. For Paper I, I developed a dataset of 37 eukaryotic proteins of bacterial origin (euBac), representing the conservative protein core of the proto-mitochondrion. READ MORE

  2. 2. Image Analysis for Diagnostics of Insulators with Biological Contamination

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Andreas Dernfalk; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; climate chamber; fungi; composite insulators; biological contamination; digital image analysis; Outdoor insulation; algae; leakage current measurements;

    Abstract : Composite insulators have a number of advantages compared to conventional insulators. However, the fact that they are more prone to aging is a major drawback. For instance, biological growths, like algae and fungi, have been found to colonize composite insulators, and possibly effecting the performance of the materials. READ MORE

  3. 3. Microbial Biofilms in the Bioinformatics Era

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kemal Sanli; Göteborgs universitet.; Gothenburg University.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metagenomics; bioinformatics software; microbial biofilms; Next Generation Sequencing; pathway analysis; periphyton; marine biofilms; FANTOM; PACFM; PACFM; Next Generation Sequencing; bioinformatics software; marine biofilms; periphyton; microbial biofilms; pathway analysis; FANTOM;

    Abstract : Adverse effects of anthropogenic impact on the environment have become conspicuous in the past century and among others include the gradual increase in the global CO2 levels, the contamination of air, soil and water by toxic chemicals, and the emergence of antimicrobial resistance among pathogenic microbial species. Microorganisms partake in an extreme diversity of activities in the environment, and hence, constitute the prime candidates to be investigated in understanding of the progression and effects of the aforementioned environmental hazard scenarios.

  4. 4. Gene expression and antibiotic resistance in Escherichia coli from Swedish inland waters

    University dissertation from Örebro : Örebro universitet

    Author : Sirirat Poonlapthawee; Jana Jass; Per-Erik Olsson; Allan Sirsjö; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi;

    Abstract : Extensive use of antibiotics both from human-medicine and veterinary sources are believed to provide selective pressure on bacteria that leads to an increase in antibiotic resistance in environmental waters. Contamination of antibiotic resistant microbes will raise human health risks. READ MORE

  5. 5. Microalgae - future bioresource of the sea?

    University dissertation from Örebro : Örebro universitet

    Author : Martin Olofsson; Catherine Legrand; Jukka Seppälä; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microalgae; algal cultivation; bioresource; bioenergy; CO2 mitigation; multi-species community approach; seasonal variation; Akvatisk ekologi; Aquatic Ecology; Bioteknik; Biotechnology; Environmental technology; Miljöteknik;

    Abstract : Unicellular microalgae are a renewable bioresource that can meet the challenge forfood and energy in a growing world population. Using sunlight, CO2, nutrients,and water, algal cells produce biomass in the form of sugars, proteins and oils, allof which carry commercial value as food, feed and bioenergy. READ MORE
