Abstract
Foreliggende oppfinnelse vedrører en fremgangsmåte for enzymatisk avsverting av avfallspapir innbefattende kopiert papir og blekkstråletrykt papir trykt med ikke-mekanisk og ikke-dispergerbart blekk ved bruk av cellefri kultur supernatant av Vibrio alginolyticus eller immobiliserte celler av samme bakterie med aksesjonsnummerNIO/DI/32 og deponert ved ARS Patent Culture Collection, USA, under nummer NRRL-B-3063 8. Oppfinnelsen vedrører videre avfarging av kontoravfallspapirmasse innen 72 timer etter kontakt av nevnte enzymer fra nevnte bakterie i massen med 3-12 % konsistens i sjøvann. Avfargingen erholdes ved bruk av ekstracellulære enzymer produsert av bakterien NIO/DI/32 dyrket i næringskraft supplert med stivelse eller Tween-80.The present invention relates to a process for the enzymatic deinking of waste paper including copied paper and inkjet printed paper printed with non-mechanical and non-dispersible ink using cell-free culture supernatant of Vibrio alginolyticus or immobilized cells of the same bacterium with accession number NIO / DI / 32 ARS Patent Culture Collection, USA, under number NRRL-B-3063 8. The invention further relates to the decolorization of office waste pulp within 72 hours after contact of said enzymes from said bacterium in the pulp with 3-12% consistency in seawater. The decolorization is obtained using extracellular enzymes produced by the bacterium NIO / DI / 32 grown in nutrient power supplemented with starch or Tween-80.
