    Sammanfattning : Most free-living bacteria will encounter different environments and it is therefore critical to be able to rapidly adjust to new growth conditions in order to be competitively successful. Responding to changes requires efficient gene regulation in terms of transcription, RNA stability, translation and post-translational modifications. LÄS MER

  3. 2. Growth in Aging Colonies : The Importance of Being Different

    Författare :Marie Wrande; Diarmaid Hughes; Måns Ehrenberg; Mikael Rhen; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : The accumulation of rifampicin resistant (RifR) mutants in aging bacterial colonies has previously been attributed to stress-induced mutagenesis. Mutations giving rise to RifR are located in the rpoB gene, coding for the β subunit of RNA polymerase, RpoB. LÄS MER

  4. 3. Transcription regulation and growth phase transition in hyperthermoacidophilic archaea

    Författare :Kun Wang; Ann-Christin Lindås; Finn Werner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Archaea; Sulfolobus; Transcription regulation; Lrp; TetR; BarR; ChIP-seq; RNA-seq; Transcriptome; growth phase transition; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Organisms from the domain Archaea are ubiquitously represented on our planet and encompass diverse fascinating organisms. The genus Sulfolobus belonging to the phylum Crenarchaeota including hyperthermoacidophilic strains that grow optimally at 65-85°C and pH 2-3. LÄS MER

  5. 4. A Parametric Approach to Yeast Growth Curve Estimation and Standardization

    Författare :Ilona Pylvänäinen; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bioscreen; Chapman-Richards model; growth curve; growth rate; lag time; optical density OD ; Saccharomyces cerevisiae; standardized curve; stationary phase OD increment; summary curve; optical density OD ;

    Sammanfattning : The purpose of this thesis is to contribute to the understanding of yeast growth. It builds upon a dataset consisting of growth curves of 576 Saccharomyces cerevisiae mutants in eight different environments. The data will be a part of a publicly available phenotypic library, PROPHECY, containing growth curves and characteristics of viable S. LÄS MER

  7. 5. Functional Profiling Of Metabolic Regulation In Marine Bacteria

    Författare :Saraladevi Muthusamy; Jarone Pinhassi; Torsten Thomas; Sarala Devi Muthusamy; Institutionen för biologi och miljö (BOM) Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marine microbiology; physiology; heterotrophic bacteria; adaptive strategies; survival; proteomics; growth phase; proteorhodopsin; inorganic sulphur oxidation; anaplerotic CO2 fixation; Miljövetenskap; Environmental Science;

    Sammanfattning : Oceans are powered by active, metabolically diverse microorganisms, which are important in regulating biogeochemical cycles on Earth. Most of the ocean surface is often limited by nutrients, influencing bacterial growth and activities. LÄS MER
