• A metagenomic study of the microbial communities in four parallel biogas reactors 

      Solli, Linn; Håvelsrud, Othilde Else; Horn, Svein Jarle; Rike, Anne Gunn Larsen (Journal article; Peer reviewed, 2014)
      This study showed that four parallel reactors co-digesting manure and fish waste silage operated stably during a startup phase. Several important Archaea and Bacteria degrading the protein-rich substrate were identified. ...
    • Biogas production from food waste via co-digestion and digestion-effects on performance and microbial ecology 

      Zamanzadeh, Mirzaman; Hagen, Live Heldal; Svensson, Kine; Linjordet, Roar; Horn, Svein Jarle (Journal article; Peer reviewed, 2017-12-15)
      In this work, performance and microbial structure of a digestion (food waste-only) and a co-digestion process (mixture of cow manure and food waste) were studied at mesophilic (37°C) and thermophilic (55°C) temperatures. ...
    • CNash - A novel parameter predicting cake solids of dewatered digestates 

      Svennevik, Oda Marie Kjørlaug; Beck, Greeley; Rus, Ester; Westereng, Bjørge; Higgins, Matthew; Solheim, Odd Egil; Nilsen, Pål Jahre; Horn, Svein Jarle (Journal article; Peer reviewed, 2019-04-23)
      Efficient digestate dewatering is crucial to reduce the volume and transportation cost of solid residues from anaerobic digestion (AD) plants. Large variations in dewatered cake solids have been reported and predictive ...
    • Effects of post anaerobic digestion thermal hydrolysis on dewaterability and moisture distribution in digestates 

      Svennevik, Oda K; Solheim, Odd Egil; Beck, Greeley; Sørland, Geir; Jonassen, Kjell Rune; Rus, Ester; Westereng, Bjørge; Horn, Svein Jarle; Higgins, Matthew J; Nilsen, Pål Jahre (Journal article; Peer reviewed, 2019)
      Organic waste fractions such as sewage sludge, food waste and manure can be stabilized by anaerobic digestion (AD) to produce renewable energy in the form of biogas. Following AD, the digested solid fraction (digestate) ...
    • Microbial biogas production from hydrolysis lignin: Insight into lignin structural changes 

      Mulat, Daniel Girma; Dibdiakova, Janka; Horn, Svein Jarle (Journal article; Peer reviewed, 2018)
      Background: The emerging cellulosic bioethanol industry will generate huge amounts of lignin-rich residues that may be converted into biogas by anaerobic digestion (AD) to increase the output of energy carriers from the ...
    • Starch Rich Chlorella vulgaris: High-Throughput Screening and Up-Scale for Tailored Biomass Production 

      Carnovale, Giorgia; Rosa, Filipa; Shapaval, Volha; Dzurendova, Simona; Kohler, Achim; Wicklund, Trude; Horn, Svein Jarle; Barbosa, Maria J.; Skjånes, Kari (Peer reviewed; Journal article, 2021-09-28)
      The use of microalgal starch has been studied in biorefinery frameworks to produce bioethanol or bioplastics, however, these products are currently not economically viable. Using starch-rich biomass as an ingredient in ...
