   Sammanfattning : The pulp and paper industry is entering a new era. Pulp mills will be transformed to biorefineries that produce not only pulp, but also biofuels and novel products from lignocellulose. This thesis addresses problems connected with the industrial transition to environmental-friendly technologies and the implementation of the biorefinery concept. LÄS MER

3. 2. Industrial applications and properties of oxalate-degrading enzymes

   Författare :Sandra Winestrand; Leif J. Jönsson; Thomas Nilsson; Nils-Olof Nilvebrant; Gudmundur O. Hreggvidsson; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Oxalic acid; oxalate oxidase; oxalate decarboxylase; calcium oxalate; scaling; active packaging; Kemi; Chemistry;

   Sammanfattning : Oxalate-degrading enzymes were investigated with focus on potential applications in the pulp and paper industry and in active packaging. Changes introduced to make the pulp and paper industry more environmentally friendly, such as recirculation of process-water streams and elementary chlorine free bleaching of pulp, have led to increasing problems with precipitation of calcium oxalate.
