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 ... -
Culture adaptation for enhanced biogas production from birch wood applying stable carbon isotope analysis to monitor changes in the microbial community
Hashemi, Behnam; Solli, Linn; Lien, Kristian Myklebust; Lamb, Jacob Joseph; Horn, Svein Jarle (Peer reviewed; Journal article, 2023-05-06)Birch wood is a potential feedstock for biogas production in Northern Europe; however, the lignocellulosic matrix is recalcitrant preventing efficient conversion to methane. To improve digestibility, birch wood was thermally ... -
Developing a biogas centralised circular bioeconomy using agricultural residues - Challenges and opportunities
Feng, Lu; Aryal, Nabin; Li, Yeqing; Horn, Svein Jarle; James Ward, Alastair (Peer reviewed; Journal article, 2023-04-10)Anaerobic digestion (AD) can be used as a stand-alone process or integrated as part of a larger biorefining process to produce biofuels, biochemicals and fertiliser, and has the potential to play a central role in the ... -
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) ... -
Metabolic pathways for biosynthesis and degradation of starch in Tetraselmis chui during nitrogen deprivation and recovery
Carnovale, Giorgia; Lama, Carmen; Torres, Sonia; Rosa, Filipa; Mantecon, Lalia; Horn, Svein Jarle; Skjånes, Kari; Infante, Carlos (Peer reviewed; Journal article, 2022-04-29)Tetraselmis chui is known to accumulate starch when subjected to stress. This phenomenon is widely studied for the purpose of industrial production and process development. Yet, knowledge about the metabolic pathways ... -
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 ... -
Starch-Rich Microalgae as an Active Ingredient in Beer Brewing
Carnovale, Giorgia; Leivers, Shaun Allan; Rosa, Filipa; Norli, Hans Ragnar; Hortemo, Edvard; Wicklund, Trude; Horn, Svein Jarle; Skjånes, Kari (Peer reviewed; Journal article, 2022-05-17)Microalgal biomass is widely studied for its possible application in food and human nutrition due to its multiple potential health benefits, and to address raising sustainability concerns. An interesting field whereby to ... -
