Resumen:
The separation of xylanase (Xyl) from a fungal extract obtained by submerged fermentation (SmF) was carried out using precipitation with natural polyelectrolytes ɩ-carrageenan (Carr) and chitosan (CHS). Xyl activity determined from the fungal extract at different times was modeled by mixed linear model for longitudinal data considering the factors as fixed effects and the experimental units as random effects. A spline regression was used to model the Xyl activity with knots at days 2 and 3 and interaction between three factors (p
