Abstract Pectin rich wastes and waste dump yard soils were screened and eighty pectinolytic fungal isolates were obtained by enrichment culturing and ruthenium red plate assay. Eight isolates with higher zones of pectin hydrolysis were selected and tested for polygalacturonase production. One isolate identified as Aspergillus awamori MTCC 9166 with highest polygalacturonase activity was tested for utilization of raw pectins for enzyme production. Polygalacturonase production was high in raw pectin sources like Orange peel (16.8 U/ml) Jack fruit rind (38 U/ml) Carrot peel (36U/ml) and Beet root peel (24U/ml). Selected Aspergillus awamori MTCC 9166 was found to be having good polygalacturonase, xylanase, cellulase and weak amylase and protease activities. This isolate with multi-enzyme production could have application for enzymes production and degradation of fruit and vegetable waste in the process of urban waste disposal.
