  2. 1. Glycolytic flux regulation in Saccharomyces cerevisiae during anaerobic growth and starvation

    Author : Elisabeth Thomsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Saccharomyces; Yeast; Starvation; Energetics; Chemostat; Anaerobic;

    Abstract : The physiology of S. cerevisiae under anaerobic growth conditions is of interest not least during implementation and development of industrial yeast-catalysed ethanol fermentations in order to maintain a productive yeast population. READ MORE

  4. 2. Sediment remediation using activated carbon: amending knowledge gaps

    Author : Robert A. Rämö; Jonas S. Gunnarsson; Agnes M. L. Karlson; Francisco J. A. Nascimento; Barbara Beckingham; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sediment contamination; sediment remediation; sorbent amendment; activated carbon; benthic community; macroinvertebrates; Baltic Sea; Marine Ecotoxicology; marin ekotoxikologi;

    Abstract : Many coastal sediments have accumulated large quantities of contaminants from past anthropogenic activities and now act as a secondary emission source of legacy pollutants to coastal ecosystems. New sediment remediation strategies are needed to address widespread sediment pollution. READ MORE

  5. 3. Metabolic analysis of shikimic acid producing Escherichia coli

    Author : Louise Johansson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Biokemi; metabolism; Chemical technology and engineering; transcriptome analysis; phosphorus-limitation; carbon-limitation; fed-batch; chemostat; batch; fermentation technology; Escherichia coli; shikimic acid; Biotechnology; Bioteknik; Metabolism; Biochemistry; principal component analysis; 2D-fluorescence spectrophotometry; metabolic flux analysis; carbon-rich;

    Abstract : Shikimic acid production using recombinant E.coli has been developed during the past 15 years due to the increased demand of this product, primarily as a starting material for the anti-influensa medicine Tamiflu?. A detailed metabolic analysis of a shikimic acid producing E. READ MORE

  6. 4. Effects of nitrogen deposition on the growth, metabolism and activity of ectomycorrhizal fungi

    Author : Magnus Ellström; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nitrogen deposition; Ectomycorrhizal fungi; Symbiosis; SOM modification; Carbon starvation; Metabolism; Nitrogen leakage; IR-spectroscopy; Mesh bags; Microarray; Axenic growth; Transcriptomics.;

    Abstract : Elevated nitrogen (N) deposition is an environmental problem that can affect plants and microorganisms, which are vital for the terrestrial N and carbon (C) cycles. This thesis has investigated the response of ectomycorrhizal fungi (EMF) to increased N deposition. READ MORE

  7. 5. Stress response regulation and protein aggregate inheritance in Caulobacter crescentus

    Author : Frederic Dominique Schramm; Kristina Jonas; Franz Narberhaus; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stress; protein aggregation; cellular aging; molecular chaperones; heat shock response; DnaK; sigma factor; suppressor genes; DNA replication; starvation; Caulobacter crescentus; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Many stress conditions a cell encounters threaten the continuation of basic biological processes ultimately endangering its survival. Heat shock and antibiotic exposure can lead to a sudden surge of protein un- and misfolding, while nutrient starvation directly causes a lack of energy and molecular building blocks. READ MORE
