Abstract
Bacterial pectinase enzyme is very much important at industrial level for different processes This present study focus on bacterial pectinase. Pectinase producing bacterial spp.is screen out from soil. About seven cultures of bacterial spp. were isolated from farmland soil sample using pectin agar plates. The selected isolates showed the zone of hydrolysis to confirmed the production of pectinase from the isolates. Among them the culture S4 showed prominent zone of hydrolysis surrounding the colony. Pectinase activity of each isolate were checked at an interval of 24 hrsusing DNSA method to access the enzyme efficiency produced by respective isolates. Keeping the ideal growth conditions the highest pectinase activity obtained among isolates was 11.43 U/ ml, by culture S4.Optimum condition for pectinase production was found at 72hrs. incubation period, 37˚C temperature and alkaline pH of 10 could be the optimum cultural conditions for bacterial strain S4. Bacterial strain S4 gave 40.85 U/ml partially purified enzyme.
