Novel archaeal thermostable cellulases from an oil reservoir metagenome
Lewin, Anna; Zhou, Jinglie; Pham, Vu Thuy Trang; Haugen, Tone; El Zeiny, Mohamed; Aarstad, Olav Andreas; Liebl, Wolfgang; Wentzel, Alexander; Liles, Mark R. (Peer reviewed; Journal article, 2017)Microbial assemblages were sampled from an offshore deep sub-surface petroleum reservoir 2.5 km below the ocean floor off the coast of Norway, providing conditions of high temperature and pressure, to identify new thermostable ... -
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 ... -
