      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

      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 ...
