Abstract

The objective of the research was to produce, isolate and characterise lipase from Aspergillus niger, and therefore inducted it by using palm oil. The lipase enzyme was produced through a batch fermentation process in a 1.4 liters-fermentor. Fermentation was carried out at room temperature, initial pH of 7, the stirring speed of 250 rpm, aeration rate of 1 vvm, and inducer concentration of 3%-m/v palm oil/ml. Enzymes was characterised at several temperature and pH variations. The lipase showed the optimum performance at pH of 7 and temperature of 30 °C with the activity of 1.5 U / ml. Isolation of lipase yielded a 4-times-increase in its activity by using 90% ammonium sulfate.
