    • Highly thermostable carboxylic acid reductases generated by ancestral sequence reconstruction 

      Thomas, Adam; Cutlan, Rhys; Finnigan, William; van der Giezen, Mark; Harmer, Nicholas (Peer reviewed; Journal article, 2019)
      Carboxylic acid reductases (CARs) are biocatalysts of industrial importance. Their properties, especially their poor stability, render them sub-optimal for use in a bioindustrial pipeline. Here, we employed ancestral ...

    • Inflammatorisk tarmsykdom og vurdering av tarmmikrobiota. 

      Vedvik, Victoria (Bachelor thesis, 2023)
      Inflammatorisk tarmsykdom (IBD) er en utbredt sykdom, spesielt i den vestlige verden. IBD klassifiseres normalt under to sykdommer; ulcerøs kolitt (UC) og Crohns sykdom (CD). Årsaken til IBD er ennå ikke kjent, men det er ...
