A C4-oxidizing lytic polysaccharide monooxygenase cleaving both cellulose and cello-oligosaccharides
Isaksen, Trine; Westereng, Bjørge; Aachmann, Finn Lillelund; Agger, Jane; Kracher, Daniel; Kittl, Roman; Ludwig, R.; Haltrich, Dietmar; Eijsink, Vincent; Horn, Svein Jarle (Journal article; Peer reviewed, 2014)Lignocellulosic biomass is a renewable resource that significantly can substitute fossil resources for the production of fuels, chemicals, and materials. Efficient saccharification of this biomass to fermentable sugars ... -
Bioenergy from brown seaweeds
Horn, Svein Jarle (Dr. ingeniøravhandling, 0809-103X; 2000:105, Doctoral thesis, 2000)Brown seaweeds lack lignin and have a low cellulose content. Thus, seaweeds should be an easier material for biological degradation than land plants. However, seaweeds have a complex composition, and complete degradation ... -
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)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 ... -
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) ... -
Potential role of sulfide precipitates in direct interspecies electron transfer facilitation during anaerobic digestion of fish waste
Hashemi, Seyedbehnam; Horn, Svein Jarle; Lamb, Jacob Joseph; Lien, Kristian Myklebust (Peer reviewed; Journal article, 2022)Fish waste (FW) contains large amounts of protein and is a challenging feedstock for biogas production due to possible H₂S and ammonia generation. Adding FeCl3 to an anaerobic digester can precipitate H₂S. Mackinawite and ... -
Production, characterization, and application of an alginate lyase, AMOR_PL7A, from hot vents in the Arctic mid-ocean ridge
Vuoristo, Kiira; Fredriksen, Lasse; Oftebro, Maren; Arntzen, Magnus Øverlie; Aarstad, Olav Andreas; Stokke, Runar; Steen, Ida Helene; Hansen, Line Degn; Schüller, Reidar Barfod; Aachmann, Finn Lillelund; Horn, Svein Jarle; Eijsink, Vincent (Peer reviewed; Journal article, 2019)Enzymatic depolymerization of seaweed polysaccharides is gaining interest for the production of functional oligosaccharides and fermentable sugars. We describe a thermostable alginate lyase belonging to Polysaccharide Lyase ... -
Stimulating biogas production from steam-exploded birch wood using Fenton reaction and fungal pretreatment
Hashemi, Seyedbehnam; Solli, Linn; Aasen, Roald; Lamb, Jacob Joseph; Horn, Svein Jarle; Lien, Kristian Myklebust (Peer reviewed; Journal article, 2022)Delignification of steam-exploded birch wood (SEBW) was stimulated using a pretreatment method including Fenton reaction (FR) and fungi. SEBW was employed as a substrate to optimize the Fe(III) and Fe(II) dosage in FR. ... -
Visible light-exposed lignin facilitates cellulose solubilization by lytic polysaccharide monooxygenases
Kommedal, Eirik; Angeltveit, Camilla Fløien; Klau, Leesa Jane; Ayuso-Fernandez, Ivan; Arstad, Bjørnar; Antonsen, Simen; Stenstrøm, Yngve; Ekeberg, Dag; Gírio, Francisco; Carvalheiro, Florbela; Horn, Svein Jarle; Aachmann, Finn Lillelund; Eijsink, Vincent (Peer reviewed; Journal article, 2023)Lytic polysaccharide monooxygenases (LPMOs) catalyze oxidative cleavage of crystalline polysaccharides such as cellulose and are crucial for the conversion of plant biomass in Nature and in industrial applications.
