Production and Recovery of Exo-polygalacturonase from Umbu (Spondias tuberosa) Residue

The objective of the present work was to produce exo-polygalacturonase by solid-state fermentation of the dehydrated peels of umbu (Spondias tuberosa) using Aspergillus niger CCT 0916 and then, using a biphasic aqueous system, recover the enzyme. The peels were dehydrated at 55 °C to obtain the dried residue and then used to produce the exo-polygalacturonase using Aspergillus niger CCT 0916 and solid-state fermentation. During the 72 h...
