	  abstract     = {In this paper, naturally immobilized lipase, Carica
papaya lipase, catalyzed biodiesel production from fish oil was
studied. The refined fish oil, extracted from the discarded parts of
fish, was used as a starting material for biodiesel production. The
effects of molar ratio of oil: methanol, lipase dosage, initial water
activity of lipase, temperature and solvent were investigated. It was
found that Carica papaya lipase was suitable for methanolysis of fish
oil to produce methyl ester. The maximum yield of methyl ester
could reach up to 83% with the optimal reaction conditions: oil:
methanol molar ratio of 1: 4, 20% (based on oil) of lipase, initial
water activity of lipase at 0.23 and 20% (based on oil) of tert-butanol
at 40oC after 18 h of reaction time. There was negligible loss in
lipase activity even after repeated use for 30 cycles.},
