Packed-bed reactor running on babassu oil and glycerol to produce monoglycerides by enzymatic route using immobilized Burkholderia cepacia lipase

Appl Biochem Biotechnol. 2010 May;161(1-8):372-81. doi: 10.1007/s12010-009-8858-7.

Abstract

The aim of this study was the glycerolysis of babassu oil catalyzed by immobilized lipase from Burkholderia cepacia, in a continuous packed-bed reactor. The best reaction conditions were previously established in batchwise via response surface methodology as a function of glycerol-to-oil molar ratio and reaction temperature. The reactor operated continuously for 22 days at 50 degrees C, and during the first 6 days, no significant decrease on the initial lipase activity was observed. Monoglycerides concentration was in the range from 25 to 33 wt.%. Subsequently, a progressive decrease in the activity was detected, and an inactivation profile described by Arrhenius model estimated values of 50 days and 1.37 x 10(-2) h(-1) the half-life and deactivation coefficient, respectively.
