Abstract

In debarking the bark is removed from wood along the cambial layer. Pretreatment with pectinases improves the efficiency of mechanical debarking measured as reduction of energy consumption in a laboratory scale debarker. The effects of different pectinases vary significantly depending on the side activities of the enzyme preparations The main carbohydrate components identified in spruce cambium were galacturonic acid, glucose, galactose, arabinose and xylose Purified polygalacturonases solubilized galacturonic acid from isolated cambium, but neutral sugars, especially glucose were not solubilized as efficiently as by the commercial pectinase preparation shown to be effective in the preteatments.
