1. 11. Biogas Production from Lignocellulosic Biomass : Impact of pre-treatment, co-digestion, harvest time and inoculation

   Författare :Chao LI; Bioteknik; []
   Nyckelord :Anaerobic digestion; Lignocellulosic biomass; Pretreatment; Co-digestion; Inoculation;

   Sammanfattning : Biogas or methane production through anaerobic digestion (AD) is gaining increasing attention worldwide due to concerns over global warming, energy security and the need for sustainable waste management. AD of lignocellulosic biomass is one facet that is highly appreciated since the conflict over biomass for food/feed or energy can be avoided. LÄS MER

3. 12. Biofilms in Nitrogen Removal - Bacterial Population Dynamics and Spatial Distribution

   Författare :Robert Almstrand; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AOB; NOB; biofilms; image analysis; FISH; Nitrosomonas; population dynamics; spatial distribution;

   Sammanfattning : Efficient nitrogen removal at wastewater treatment plants (WWTPs) is necessary to avoid eutrophication of recipient waters. The most commonly used approach consists of aerobic nitrification and subsequent anaerobic denitrification resulting in the release of dinitrogen gas into the atmosphere. LÄS MER

4. 13. Nitrifyers in constructed wetlands treating landfill leachates

   Författare :Carina Sundberg; Per-Eric Lindgren; Karin Sundblad-Tonderski; Jenny Stendahl; Hans Brix; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Landfill leachate is produced many years after a landfill site closes. Hence, treatment by “natural methods”, as e.g. constructed wetlands, with low management requirements is attractive. LÄS MER
