Abstract: We studied the enzyme kinetics of Tara fiber residues before and after bleaching. By the Lineweaver-Burk double reciprocal plot method, we used the reciprocals of sample concentration and enzymatic reaction rate to plot and construct Michaelis equation. Km value of two substrates were 12.73 mg·mL-1 and 192 mg·mL-1 by calculating, respectively, and the Tara fiber residues was more suitable than the bleached Tara fiber residues. The sample of bleached Tara fiber residues had lower lignin content by FTIR.

Key words: Tara, fiber residues, bleaching, enzyme kinetics, Michaelis equation
