Determination of Various Parameters of Crude and Partially Purified Dialysed Pectinase Enzyme Produced from Aspergillus Niger Using Pineapple Peels

Authors(3) :-B. Leelamani, Dr. D. Sailaja, Dr. K. Kamala

The agricultural wastes generated from pineapple (Ananas cosmosus) represents about 35% of the entire fruit. These wastes can be converted to most useful products such as pectin. Pectin was extracted from pineapple peels with a percentage yield of 8.33% at pH 2.2 and temperature of 70° C. Three pectinolytic fungi: Aspergillus niger, Aspergillus fumigatus and Aspergillus flavus were isolated from natural sources and tested for their pectinolytic activity. In submerged fermentation system containing pineapple pectin broth, Aspergillus niger was inoculated and incubated for 4 days. The crude enzyme pectinase was harvested after fermentation by filteration process. Crude enzyme obtained from Aspergillus niger was precipitated with 80% ammonium sulphate saturation. The dialysis is carried out according to Dixon and Webb (1964) for 12 hours to obtain partially purified enzyme. Then the protein concentration and activities of the crude and dialyzed pectinase enzymes were compared.
