  1. 6. Culture-independent methods and high-throughput sequencing applied to evolutionary microbial genomics

    Författare :Anders E. Lind; Thijs JG Ettema; Purificación López-García; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Single cell genomics; metagenomics; amplicon; archaea; haloarchaea; endosymbiosis; ciliate; hydrogenosome; tree reconciliation;

    Sammanfattning : Culture-independent methods allow us to better understand the diversity of microorganisms on earth. By omitting the culturing step, we can gain access to species previously out of our reach.To better capture and understand the diversity of microorganisms, we have developed an alternative to 16S amplicon sequencing.

  3. 7. Unique Solutions to Universal Problems : Studies of the Archaeal Cell

    Författare :Erik A. Pelve; Rolf Bernander; Sonja Verena Albers; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Archaea; Cdv; Cell cycle; Cell division; Cell lysis; Crenarchaea; ESCRT-III; Flow cytometry; Microarray; Microscopy; Nitrosopumilus; SIRV2; Sulfolobus; Thaumarchaea; Transcription; VAP; Virus; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Sammanfattning : Archaea is one of the three domains of life and studies of archaeal biology are important for understanding of life in extreme environments, fundamental biogeochemical processes, the origin of life, the eukaryotic cell and their own, unique biology. This thesis presents four studies of the archaeal cell, using the extremophilic Sulfolobus and ocean living Nitrosopumilus as model systems. LÄS MER

  4. 8. The cell cycle of the hyperthermophilic archaeal genus Sulfolobus

    Författare :Karin Hjort; Patrick Dennis; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; Cell cycle; Sulfolobus; Archaea; Origin; Replication; SIRV2; Mikrobiologi; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar; mikrobiologi; Microbiology;

    Sammanfattning : The third domain of life, Archaea is one of the three main evolutionary lineages together with the Bacteria and the Eukarya domains. The archaea are, despite their prokaryotic cell organisation, more closely related to eukaryotes than to bacteria in terms of the informational pathways (DNA replication, transcription and translation).

  5. 9. 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

  7. 10. Investigations of the microbial diversity and dynamics in activated sludge using molecular methods

    Författare :Johan Fredriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater treatment; 16S rRNA; population dynamics; terminal restriction fragment length polymorphism; microbial ecology; Archaea; activated sludge; Bacteria;

    Sammanfattning : Wastewater treatment is necessary to reduce the health risks and environmental impacts associated with discharge of untreated wastewater. The most common way to treat wastewater in wastewater treatment plants is through the activated sludge process. LÄS MER
