The vast majority of the industrial use of enzymes is covered from microorganisms. Microorganisms are favoured in industry because of their several advantages for example rapid growth, short life expectancy and simplicity in doing genetic alterations. Microbial enzymes are thus amply provided, very much standardized and promoted by many companies. Among various enzymes, Pectinases hold an exceptional place because of its different uses in various sectors like food, textile and biofuel industries.A total of 25% of total enzyme market is being shared by Pectinase alone.The current study was carried out to evaluate the pectinase activity of the pectinolytic bacteria. 40 Bacterial strains were isolated from different soil samples and screened for Pectinase production. Primary and Secondary screening showed 3 potential isolates I38 , I39 and I40 showing pectin degradation on Vincent’s media. Further, extracellular pectinase was partially purified by ammonium sulphate precipitation and dialysis. Sequential ammonium sulphate saturations from 20-80% i.e. (20, 40, 60 and 80%) showed 60% ammonium sulphate was optimum for precipitation of intracellular enzyme whereas 80% was optimum for extracellular enzyme.
