Chitosan as a wound dressing starting material: antimicrobial Properties and mode of action
Matica, Mariana Adina; Aachmann, Finn Lillelund; Tøndervik, Anne; Sletta, Håvard; Ostafe, Vasile (Peer reviewed; Journal article, 2019)Fighting bacterial resistance is one of the concerns in modern days, as antibiotics remain the main resource of bacterial control. Data shows that for every antibiotic developed, there is a microorganism that becomes ... -
Identification of a Pivotal Residue for Determining the Block Structure-Forming Properties of Alginate C-5 Epimerases
Stanisci, Annalucia; Tøndervik, Anne; Gaardløs, Margrethe; Lervik, Anders; Skjåk-Bræk, Gudmund; Sletta, Håvard; Aachmann, Finn Lillelund (Peer reviewed; Journal article, 2020)Alginate is a linear copolymer composed of 1→4 linked β-d-mannuronic acid (M) and its epimer α-l-guluronic acid (G). The polysaccharide is first produced as homopolymeric mannuronan and subsequently, at the polymer level, ... -
Molecular insights into alginate β-lactoglobulin A multivalencies—The foundation for their amorphous aggregates and coacervation
Madsen, Mikkel; Prestel, Andreas; Madland, Eva; Westh, Peter; Tøndervik, Anne; Sletta, Håvard; Peters, Günther H. J.; Aachmann, Finn Lillelund; Kragelund, Birthe B.; Svensson, Birte (Peer reviewed; Journal article, 2023)For improved control of biomaterial property design, a better understanding of complex coacervation involving anionic polysaccharides and proteins is needed. Here, we address the initial steps in condensate formation of ... -

Courtade, Gaston; Le, Simone Balzer; Sætrom, Gerd Inger; Brautaset, Trygve; Aachmann, Finn Lillelund (Peer reviewed; Journal article, 2017) -
Overall size of mannuronan C5-Epimerases influences their ability to epimerize modified alginates and alginate gels
Stanisci, Annalucia; Aarstad, Olav Andreas; Tøndervik, Anne; Sletta, Håvard; Dypås, Lene Brattsti; Skjåk-Bræk, Gudmund; Aachmann, Finn Lillelund (Peer reviewed; Journal article, 2018)A family of seven mannuronan C5-epimerases (AlgE1-AlgE7) produced by Azotobacter vinelandii is able to convert β-d-mannuronate (M) to its epimer α-l-guluronate (G) in alginates. Even sharing high sequence homology at the ... -
Variations in the chemical composition of Norwegian cultivated brown algae Saccharina latissima and Alaria esculenta based on deployment and harvest times
Arlov, Øystein; Nøkling-Eide, Katharina; Aarstad, Olav Andreas; Jacobsen, Synnøve Strand; Langeng, Anne-Mari; Borrero Santiago, Ana Rocio; Sæther, Maren; Rustad, Turid; Aachmann, Finn Lillelund; Sletta, Håvard (Peer reviewed; Journal article, 2024)Brown algae exhibit large seasonal variation in their composition based on nutrient and sunlight access, as well as other environmental factors. The continued growth of brown algae cultivation in Europe is dependent on ...
