2. 11. Antibiotic sensitivity and horizontal gene transfer in Escherichia coli - A genome-wide perspective

   Author : Martin Palm; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; antibiotics; antibiotic resistance; Escherichia coli; heavy metals; bacterial conjugation; pangenome; sub-inhibitory;

   Abstract : Since their discovery in the early 20th century, antibiotics have truly revolutionized human medicine. They have allowed us to treat diseases that were previously untreatable and have become a staple of modern medicine. However, along with the human use of antibiotics pathogens resistant to antibiotics emerged. READ MORE

4. 12. Enhancement of Volatile Fatty Acid Production from Dairy Wastewater

   Author : Merve Atasoy; Zeynep Cetecioglu; Juan Lema; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Volatile fatty acid; mixed culture fermentation; pure culture; bioaugmentation; bacterial community; Flyktiga fettsyror; jäsning med blandkultur; renkultur; bioaugmentering; bakteriesamhälle; Chemical Engineering; Kemiteknik;

   Abstract : Resource recovery from waste-streams is a highly promising approach to meet with urbanization and modernization consequences. Rapid human population growth, expanding industrialization and excessive consumption of resources lead to increasing demand for raw materials and energy sources, and an escalation of greenhouse gas emission.

5. 13. Extent and limitations of functional redundancy among bacterial communities towards dissolved organic matter

   Author : Martin Andersson; Eva Lindström; Stuart Jones; Uppsala universitet; []
   Keywords : Dissolved organic matter; BCC; biodiversity; functional redundancy; Mikrobiologi; Microbiology;

   Abstract : One of the key processes in the carbon cycle on our planet is the degradation of dissolved organic matter (DOM) in aquatic environments. The use of organic matter by bacteria links energy from DOM to higher trophic levels of the ecosystem when bacteria are consumed by other organisms. This is referred to as the microbial loop.

6. 14. Monitoring anti-infectives and antibiotic resistance genes : with focus on analytical method development, effects of antibiotics and national perspectives

   Author : Ghazanfar Ali Khan; Jerker Fick; Klaus Kümmerer; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; method development; on-line solid phase extraction liquid chromatography mass spectrometry SPE LC-MS MS ; antibiotics; anti-infectives; constructed wetlands CWs ; denatured gradient gel electrophoresis DGGE ; percentage removal efficiency PRE ; shannon index; antibiotic resistance genes ARGs ; real-time polymerase chain reaction RT-PCR ; drug formulation facilities DFF ; wastewater; epidemiology; pandemic; influenza; compliance;

   Abstract : Antibiotics are biologically active and are globally used in humans and animal medicine for treatment and in sub-therapeutic amounts as growth promoters in animal husbandry, aquaculture and agriculture. After excretion, inappropriate disposal and discharge from drug production facilities they enter into water bodies either as intact drugs, metabolites or transformed products. READ MORE

7. 15. The influence of soil structure on microbial processes in microfluidic models

   Author : Carlos Arellano; MEMEG; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The way microbes behave in nature can vary widely depending on the spatial characteristics of the habitats they are located in. The spatial structure of the microbial environment can determine whether and to which extent processes such as organic matter degradation, and synergistic or antagonistic microbial processes occur.
