In this study, 40°C was observed to be the optimum temperature for the production of pectinase
by Bacillus licheniformis. This result is in agreement with pectinase production by Bacillus circulans isolated from dump yards of vegetable wastes which also had the optimum temperature of 40°C (Raju and Divakar, 2013). However, it was observed that the enzyme production decreased as the temperature was
increased to 45°C. About 40% of the enzyme produced was lost at 45ºC as compared to the production at 40ºC.This may be an indication that temperature above 40°C is not suitable for pectinase production by Bacillus
licheniformis
