  2. 1. Effect of surface characteristics on cellular adherence and activity

    Author : Marjan Dorkhan; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacteria; microbial biofilm; dental implant; streptococci; oral bacteria; salivary pellicle; early colonizers; titanium oxide; microbial activity; oral keratinocytes; gingival fibroblasts; cell attachment; surface modification; anodic oxidation; anatase;

    Abstract : Ersättning av förlorade tänder med tandimplantat är numera en vanlig behandlingsmetod med generellt goda resultat. Antalet implantatsystem på den internationella marknaden har ökat kraftigt under senare år. READ MORE

  4. 2. Microbial temperature dependences in soil: The belowground feedback to climate change

    Author : Dániel Tájmel; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; soil microbial community; microbial growth; microbial respiration; temperature dependence; climate change;

    Abstract : Since the Industrial Revolution, human activities have elevated atmospheric CO2 concentrations. The consequences of this include rising temperatures, shifts in precipitation patterns, and increased intensity and frequency of extreme weather events, such as heat waves and droughts. READ MORE

  5. 3. Soil salinity as a driver of microbial community structure and functioning

    Author : Kristin Rath; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Soil salinization; Soil Microbiology; soil microbial community; Bacteria; Aerobic; Fungi; Drying-rewetting; Microbial growth; Microbial biomass; Soil respiration; salinity tolerance; Saline soils; Salinity gradient;

    Abstract : Soil salinization is a pressing agricultural problem in many areas of the world, particularly in areas heavily reliant on irrigation agriculture. While the negative effects of salinity on crop plants have been widely studied, its effects on soil microorganisms have received less attention, and the impact of soil salinity on both microbial community structure and functioning is not well understood.

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

  7. 5. Microbial life deep underground : From anaerobic cultures to reconstructed genomes

    Author : George Westmeijer; Mark Dopson; Hans Røy; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Continental deep biosphere; microbial ecology; anaerobic enrichment cultures; Candidatus Desulforudis audaxviator; Thiobacillus denitrificans; flow-cells; Mikrobiologi; Microbiology; Ecology; Ekologi;

    Abstract : The deep biosphere refers to the vast ecosystem of life beneath the Earth’s surface, residing in the fractured bedrock and pores of rocks, largely isolated from solar energy. These fractures enclose an important reservoir of groundwater that contains microorganisms active in processes such as the uptake of inorganic carbon, sulfur cycling, or the degradation of organic matter.
