Hydrolyse enzymatique de pâtes de papaterie. Dosage des sucres obtenus en fonction des traitements mécaniques

Wood pulps (from hard wood and softwood) and waste papels wele hydrolysed by an enzymatic
saccharification process. Sugars products were analysed by gaz chromatography. Typs of pulps,
mechanical treatment and enzymes have been investigated. Mechanical treatment (refining and
bearing do not significately affect copper number, degree of polymerisation and pentosan content'
Enzymic digestibiîity is enhanced during bearing. This increase digesdbility is apparently not related to the destruction of cellulose super molecular structure.
