Immobilised enzymes have the advantage that they can be
reused several times, but their activity eventually decreases due to
many factors, such as desorption, substrate deactivation, and product
inhibition phenomena which has been reported in the literature
when using enzymes for the synthesis of biodiesel. Therefore, we
tried to improve the stability of the immobilised lipase after each
use, and then compared the results obtained in our laboratory.
