Lipases are enzymes of great biotechnological relevance. Besides its natural function (hydrolysis of triglycerides), they are capable of catalyzing regio- and enantioselective hydrolysis and synthesis of numerous esters. Pseudomonas fluorescens lipase (LPF) was immobilized on different supports and with different methods and was applied on the synthesis of compounds of industrial interest. The efficiency of these syntheses with the biocatalyst PFL-octyl-silica, PFL-XAD 7 HP and PFL-polystyrene were used on the production of ethylic biodiesel from babassu oil. The best yield (100% within 24 h) was obtained with PFL immobilized on octyl-silica (PFL-octyl-silica). This derivative and commercial immobilized lipases (Candida antarctica lipase, C...
