The present study aims at exploring the production of pectinolytic enzymes from an easily available and cheaper agro-residue
(dried pineapple residue) fermented by newly isolated mixed culture of Aspergillus fumigatus and Aspergillus sydowii
through solid-state fermentation. The optimum conditions that influence the extraction of pectinases from the fermented
substrate were temperature, pH and incubation period, 35°C, 5.0 and 48h respectively. Among the carbon sources tested for
maximum production of enzymes, 2% starch yielded maximum polygalacturonase (PG), whereas 3% sucrose yielded pectin
lyase (PL) and 3% glucose enhanced production of pectate lyase (PAL).
