Utilizing a novel fungal enzymatic cocktail as an eco-friendly alternative for cellulose pulp biobleaching

Enzyme cocktails can alter the lignin and hemicellulose content in wood cell walls, improving bleaching process during pulp production offsetting need for toxic chemicals. In this study, brown was biobleached with a mixture of crude fungal extracts rich xylanase laccase, respectively produced from Aspergillus tamarii Kita Trametes versicolor on waste materials. The optimal conditions biobleaching were laccase (1 to 2 v/v), at temperature 36 °C pH 5.5. treated cellulose showed reduction Kappa number by 1.83 points, representing an efficiency 20.3%. addition, brightness increased 4.65 points comparison control. Hence, studies involving application standardized cocktail hydrolysis lignocellulosic residues, e.g., barley residue sugarcane bagasse, led formation 85 g/L 25 reducing sugars, respectively. Moreover, caused greater deinking recycled paper pulp.
