This study examines the effect of surfactant-enhanced enzymatic hydrolysis on eucalyptus Kraft pulps produced under high (CPHA) and mild (CPMA) alkali conditions to optimize saccharification sugar yield. Compositional analysis revealed an increase in glucan content, from 40% untreated 70.1% CPHA. Both were hydrolyzed using Cellic® CTec3 HS enzyme (Novozymes). A 22 factorial design maximum conversion (~100%) with loading 10 FPU/g carbohydrate 10% (w/v) solids. Tween 20 significantly boosted CPMA, increasing reducing sugars 42 g/L 65 efficiency 59.6% 92.2% within 6 h. By contrast, 80 PEG 400 showed limited effects CPMA. Surfactants mitigated lignin–enzyme interactions, especially as higher lignin content restricted efficiency. Phenolic hydrolysates that increased release inhibitory compounds, while kept phenolic levels lower. Overall, improved yields even moderate removal during kraft pretreatment, highlighting its potential reduce costs industrial biorefineries. underscores importance optimizing surfactant selection based biomass composition for effective cellulosic recovery.
