Effect of pH on the stability (a) of the crude exo-polygalacturonase, produced by Pleurotus ostreatus in submerged (−) or solid-state (…) fermentation and the effect of temperature on the stability (b) of the crude exo-polygalacturonase, produced by Pleurotus ostreatus in submerged [(○)- 30 °C, (∆)- 50 °C, (◊)- 70 °C, (−)] or solid-state [(●)- 30 °C, (▲ )- 50 °C, ()- 70 °C, (…)] fermentation. Data presented were the mean values of the 3 sets of experiments (standard deviation of the relative and residual enzyme activity were within ±8% and ±7 % respectively)
