Lipase Immobilized Membrane Reactor Applied to Babassu Oil Hydrolysis

Abstract: This work deals with enzymatic hydrolysis of babassu oil by immobilized lipase in membrane reactors of two types: a flat plate nylon membrane and a hollow fiber polyetherimide membrane on which surface commercial lipases were immobilized by adsorption. Experiments conducted in the hollow fiber reactor showed that during the immobilization step enzyme adsorption followed a sigmoid model, with a maximum adsorption equilibrium time of 30 minutes. Concerning the hydrodynamics of the liquid phases, the results indi… Show more

“…The participation of lipases in the worldwide enzyme industry market has grown significantly and it is believed that, in the future, they will acquire importance comparable to that of the peptidases, which currently represent 25 to 40% of industrial enzyme sales (Hasan et al 2006). Lipases act, by definition, at the organic-aqueous interface, catalyzing the hydrolysis of estercarboxylate bonds and releasing fatty acids and organic alcohols (Pereira et al, 2003;Leal et al 2002;Kamimura et al, 1999;Merçon et al 1997). However, as Pottevin showed for the first time in 1906, in water-restricted environments, the reverse reaction (esterification) or even various transesterification reactions can occur Castilho 2008, Castro et al 2000).…”

“…At oil-water interface, it hydrolyzes carboxyl ester bond to release fatty acids and organic alcohols (Pereira et al, 2003;Leal et al, 2002;Kamimura et al, 1999;Merçon et al, 1997). In comparison with the aforementioned processes, lipase catalyzed hydrolysis has distinct advantages of excellent product purity and mild process conditions (normal pressure and nearly ambient temperature).…”

“…There is growing interest in immobilizing lipases on semi-permeable membranes to develop membrane bio-reactors wherein lipases are used as bio-catalyst and semi-permeable membrane as a mean of separation in enzyme membrane bio-reactors [8,[15][16][17]. This study is aimed to immobilize lipase (triacyl glycerol ester hydrolyses) on the laboratory prepared asymmetric membranes (polysulfone and polyether sulfone).…”
