1H, 13C and 15N backbone and side-chain assignment of a carbohydrate binding module from a xylanase from Roseburia intestinalis
Madland, Eva; Kitaoku, Yoshihito; Sætrom, Gerd Inger; Leth, Maria Louise; Ejby, Morten; Hachem, Maher Abou; Aachmann, Finn Lillelund (Journal article; Peer reviewed, 2018)The N-terminal domain (residues 28–165) from the glycoside hydrolase family 10 from Roseburia intestinalis (RiCBMx), has been isotopically labeled and recombinantly expressed in Escherichia coli. Here we report 1H, 13C and ... -
A novel expression system for lytic polysaccharide monooxygenases
Courtade, Gaston; Le, Simone Balzer; Sætrom, Gerd Inger; Brautaset, Trygve; Aachmann, Finn Lillelund (Journal article; Peer reviewed, 2017)Lytic polysaccharide monooxygenases (LPMOs) are key enzymatic players of lignocellulosic biomass degradation processes. As such, they have been introduced in cellulolytic cocktails for more efficient and less expensive ... -
Biosynthesis and Function of Long Guluronic Acid-Blocks in Alginate Produced by Azotobacter vinelandii
Aarstad, Olav Andreas; Stanisci, Annalucia; Sætrom, Gerd Inger; Tøndervik, Anne; Sletta, Håvard; Aachmann, Finn Lillelund; Skjåk-Bræk, Gudmund (Journal article; Peer reviewed, 2019)With the present accessibility of algal raw material, microbial alginates as a source for strong gelling material are evaluated as an alternative for advanced applications. Recently, we have shown that alginate from algal ... -
Functional characterisation of AlgE1-MS and AlgE1-AR, two variants of the alginate modifying enzyme AlgE1
Sollerud, Kari Fuying Platou (Master thesis, 2023)Alginat er en linær polysakkarid bestående av to C-5 epimerer: \ce{\beta-D-mannuronat} (M) og \ce{\alpha-L-guluronat} (G). Disse er bundet sammen med $1\rightarrow4$ glykosidbindinger. Alginat kan komme i mange størrelser ... -
Graphene oxide in zinc alginate films: Antibacterial activity, cytotoxicity, zinc release, water sorption/diffusion, wettability and opacity
Frigols, Belen; Marti, Miguel; Salesa, Beatriz; Hernandez-Oliver, Carolina; Aarstad, Olav Andreas; Ulset, Ann-Sissel Teialeret; Sætrom, Gerd Inger; Aachmann, Finn Lillelund; Serrano-Aroca, Angel (Peer reviewed; Journal article, 2019)Alginate is considered an exceptional biomaterial due to its hydrophilicity, biocompatibility, biodegradability, nontoxicity and low-cost in comparison with other biopolymers. We have recently demonstrated that the ... -
Karakterisering av norsk viltvoksende og kultivert Palmaria palmata
Bye, Anne Olea (Bachelor thesis, 2023)Tarearten Palmaria Palmata (P. palmata) er én av flere tarearter som vokser langs kysten i Norge. Verden er stadig på jakt etter nye matressurser, og med verdens nest lengste kystlinje har Norge et stort potensial for ... -
Preparation of 4-deoxy-L-erythro-5-hexoseulose uronic acid (DEH) and guluronic acid-rich alginate using a unique exo-alginate lyase from Thalassotalea crassostreae
Wang, Damao; Aarstad, Olav Andreas; Li, Jing; McKee, Lauren S.; Sætrom, Gerd Inger; Vyas, Anisha; Srivastava, Vaibhav; Aachmann, Finn Lillelund; Bulone, Vincent; Hsieh, Yves S. Y. (Journal article; Peer reviewed, 2018)Marine multicellular algae are considered promising crops for the production of sustainable biofuels and commodity chemicals. However, their commercial exploitation is currently limited by a lack of appropriate and efficient ... -
Sequential extraction and fractionation of four polysaccharides from cultivated brown algae Saccharina latissima and Alaria esculenta
Sandberg Birgersson, Paulina Anna Teresia; Oftebro, Maren; Strand, Wenche Iren; Aarstad, Olav Andreas; Sætrom, Gerd Inger; Sletta, Håvard; Arlov, Øystein; Aachmann, Finn Lillelund (Journal article; Peer reviewed, 2023)Norway has a well-established seaweed industry based on extraction of alginates from wild harvested brown algae, Laminaria hyperborea (LH). However, further expansion of wild harvest is limited, and cultivated seaweed can ...
