**2.2 Evaluation of deinking**

The TAPPI T-205-OM-81 standard was applied to the samples collected in the tailings stream (deinked fiber), for each experimental variation of **Table 1**. According to the mentioned standard, the quantified characteristics are whiteness, reflectance, opacity, and tonality.

#### **2.3 Molecular coupling**

The method of genetic algorithms coupled to local search or Lamarckian (AUTODOCK 3.0) was used to identify the geometry between the cellulose fragments (ligand) and the cellulase enzyme (substrate).
