Abstract-The hemicelluloses were separated from the cottonseed degradation of seed-coat fragments [2]. Cellulase could make
coat and degraded with Pulpzyme HC. The digestion degree the residual seed-coat fragments more accessible to chemicals
value was calculated by the equation depended on the release of and allow the reduction of the hydrogen peroxide consumption
reducing sugars concentration which was determined from DNS in the consecutive chemical bleaching [3]. Xylanases together
fitting curve equation. The optimum enzyme reaction with EDTA have a biobleaching effect increasing the lightness
temperature was 60℃ and pH was . The duration of 80 min
of the seed-coat fragments in the subsequent alkaline treatment
was chose as the most suitable enzymolysis time. The
degradation degree value was % when ml pure [4]. In addition fungal plexes produced by
Pulpzyme HC was
