Lipases are produced extracellular by the bacterial strain Bacillus subtilis in submerged state fermentation was purified from the cell free culture broth by ammonium sulphate precipitation at 70% saturation followed by purification solvent precipitation by acetone and ethanol. DS- PAGE analysis indicated that the enzymes protein molecular mass was 19.4 kDa. The enzyme activity was maximum growth 72 hours of incubation time, with an activity (0.95U/ml). Lipase activity was maximal at 1% concentration of the substrate. Olive oil produced (32.67) units of lipase was the best induces for lipase production enzyme activity. The optimum PH 8 for the activity of lipase.
