In this study, biodiesel production were investigated by enzymatic catalysts using various oils. In case of enzymatic process optimal conditions such as temperature, agitation speed, water contents and enzyme concentration were determined to be 45℃, 250rpm, 10% of water and 20% of immobilized lipases. Jatropha oil, Fried oil, and Dark oil were used as substrates for biodiesel production. Jatropha and Fried oil showed more than 90 % conversion rate within 4 h. However, convertible fatty acid in the dark oil was 58 %. So, conversion from dark oil to biodiesel reached just 50 % after 4 h.
