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