Abstract
Fremgangsmåte for enzymatisk behandling av trecellulosematerialer, særlig cellulosetremasser. Materialet bringes i kontakt med et enzympreparat med en vesentlig glukuronidaseaktivitet for å fjerne metallioner fra massen, for å endre massens overflateladning og for å gjøre materialet mer egnet for enzymbehandling.Process for enzymatic treatment of wood cellulose materials, especially cellulose wood pulp. The material is contacted with an enzyme preparation with a substantial glucuronidase activity to remove metal ions from the pulp, to change the surface charge of the pulp and to make the material more suitable for enzyme processing.
