Title (EN) NOVEL ENZYME PREPARATIONS AND METHODS FOR THEIR PRODUCTION
(FR) NOUVELLES PREPARATIONS D'ENZYMES ET PROCEDES DE PRODUCTION
Abstract:
(EN) Enzyme preparations enriched in hemicellulase-, pectin-, and/or lignin-degrading enzymes are described which are also partially or completely deficient in cellulase degrading activity. Such preparations may be utilized in a crude, umpurified form and are especially useful in the production of pulp and paper.
(FR) L'invention décrit des préparations enzymatiques enrichies en enzymes dégradant l'hémicellulase, la pectine et/ou la lignine et qui sont également partiellement ou totalement déficientes dans la dégradation de la cellulase. On peut utiliser ces préparations sous forme brute et non purifiée et elles sont particulièrement efficaces pour la production de la pulpe et du papier.
