  1. 1. Phylogenetic characterization of microbial mats and isolation of Thermus spp. and sulfur-oxidizing bacteria from Icelandic hot springs

    Author : Sigurlaug Skirnisdottir; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biochemical technology; hot springs; thermophiles; microbial diversity; SSU rRNA; sulfur-oxidizers; Thermus; Biotechnology; Bioteknik; Biochemistry; Biokemi; Metabolism; Biokemisk teknik;

    Abstract : Until recently, the only way to describe microbial communities was by cultivation. This is a major obstacle because typically only a small fraction of the microbes can be cultivated by standard techniques. However, the use of rRNA and molecular phylogenetic techniques has allowed us to bypass this limitation. READ MORE

  2. 2. When bioelectrochemical systems meet extremophiles, possibilities and challenges

    Author : Gaofeng Ni; Mark Dopson; Bert Hamelers; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acidophiles; psychrophiles; haloalkaliphiles; bioelectrochemical systems; microbial sulfur metabolism; 16S rRNA gene amplicon sequencing; metagenomics; metatranscriptomics; Mikrobiologi; Microbiology;

    Abstract : Extremophiles are microorganisms live and thrive in extreme environments that are harsh and hostile to most forms of life on earth (e.g. low pH, low temperature, high pH and high salinity). They have developed strategies to obtain nutrients and conserve energy to sustain life under these adverse conditions. READ MORE

  3. 3. Robustness quantification in yeast: A methodology to study phenotypic, evolutionary, and genomic aspects of microbial robustness

    Author : Cecilia Trivellin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; bioproduction; Saccharomyces cerevisiae; adaptive laboratory evolution; High-throughput; fluctuating conditions; perturbations;

    Abstract : Bioprocesses contribute to the shift towards a more sustainable economy. In bioprocesses, valuable chemicals can be generated from renewable resources while, at the same time, reducing carbon emissions. A major hurdle in bringing bio-based products to market is the time and cost involved in designing efficient cell factories. READ MORE

  4. 4. Functional Profiling Of Metabolic Regulation In Marine Bacteria

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

    Abstract : 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. READ MORE
