1. 1. Characterization of respiratory physiology in Lactococcus lactis for high-yield production of high-performance starter cultures

   Författare :Anna Johanson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; batch cultivations; lag phase; haemin haem; respiration-permissive conditions; aerobic growth; Lactic acid bacteria; acidification activity; continuous cultivations; starter culture production;

   Sammanfattning : Fermented food products are consumed world-wide, every day, and the demand is growing as intake increases. Lactococcus lactis is a lactic acid bacterium commonly used as a starter culture to produce fermented dairy products. LÄS MER

3. 2. Engineering cytosolic acetyl-CoA metabolism in Saccharomyces cerevisiae

   Författare :Yiming Zhang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reverse engineering; flavodoxin; genomic DNA sequencing; ferredoxin; histone deacetylase; adaptive evolution; ferredoxin flavodoxin NADP reductase; pyruvate decarboxylase; citrate synthase; hexose transporter; yeast; mitochondria; aerobic growth; metabolic engineering.; acetyl-CoA; central carbon metabolism;

   Sammanfattning : A Saccharomyces cerevisiae strain carrying deletions in all three pyruvate decarboxylase genes (also called Pdc negative yeast) represents a non-ethanol producing platform strain for biochemical production. However, it cannot grow on glucose as the sole carbon source due to the lack of cytosolic acetyl-CoA for lipid biosynthesis. LÄS MER

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

   Författare :Kristin Rath; MEMEG; []
   Nyckelord :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;

   Sammanfattning : 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.

5. 4. Cardiorespiratory function of euryhaline teleosts - Regulatory mechanisms, effects of warming and costs of osmoregulation

   Författare :Daniel Morgenroth; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; salinity; temperature; cardiac; vascular; gastrointestinal; acclimation; growth;

   Sammanfattning : Teleost fishes have colonized almost every aquatic habitat on earth and exhibit adaptations that allow them to thrive in environments with very diverse physico-chemical properties. One fundamental environmental variable in aquatic ecosystems is salinity, as most fish species are only able to tolerate a narrow range of salinities. LÄS MER

7. 5. Removal of Micropollutants from Wastewater in Aerobic Granular Sludge and Activated Sludge Systems

   Författare :Cecilia Burzio; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater; Pharmaceuticals; Aerobic Granular Sludge; Microbial Community; Organic Micropollutants; Biofilm; Transformation; Sorption;

   Sammanfattning : The presence of organic substances in the aquatic environment, such as pharmaceutically active compounds, antibiotics, and personal care products, has become a worldwide issue of increasing environmental concern. As they are present at nano- to microgram per liter concentrations, they are defined as organic micropollutants (OMPs). LÄS MER
