High Concentration Bio Enzyme Stonefree Enzyme For Jeans Washing Cellulase Powder Product Description Stonezyme SF is formulated with new generation neutral cellulase. Cellulose is a glucose polymer linked with β-1,4-glycosidic bonds. Cellulase system consists of three major components:endoglucanase (endo-1,4-β-D-glucanase or EG), cellobiohydrolases (exo-1,4-β-D-glucanases, or CX, or CBH), and β-glucosidases (1,4-β-D-glucosidase; BG; BGL). As illustrate in the below diagram,
