  2. 1. Microbial communities : descriptors of environmental change in marine ecosystems

    Author : Li Zhao; Agneta Andersson; Xiao-Ru Wang; Alexander Eiler; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In northern marginal seas, like the northern Baltic Sea, climate change will lead to many alterations, for example increased inflows of nutrients and dissolved organic matter (DOM). Nutrients and DOM are fundamental drivers shaping marine microbial communities, including both bacterial and phytoplankton populations. READ MORE

  4. 2. Microbial Biofilms in the Bioinformatics Era

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

    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.

    Abstract : Many factors can influence the rate of microbial degradation of organic contaminants in aquifers. Some of these factors, e.g. READ MORE

  6. 4. Microbe-mineral interactions in soil : Investigation of biogenic chelators, microenvironments and weathering processes

    Author : Engy Ahmed; Sara Holmström; Roger Finlay; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Podzol; Biotite; Apatite; Oligoclase; Microbial attachment; Siderophores; Soil microorganisms; geokemi; Geochemistry;

    Abstract : The interplay between geology and biology has shaped the Earth during billions of years. Microbe-mineral interactions are prime examples of this interplay and underscore the importance of microorganisms in making Earth a suitable environment for all forms of life. READ MORE

    Abstract : Carbon dioxide (CO2) emissions from human activities are driving climate change, but the pending crisis could be mitigated by a circular carbon economy where released CO2 is recycled into commodity chemicals. Autotrophic microbes can make a contribution by producing chemicals, such as biofuels, from CO2 and renewable energy. READ MORE
