Effect of operating variables on the hydrolysis rate of palm oil by lipase

Lipase-catalyzed Hydrolysis of Linseed Oil : Optimization Using Response Surface Methodology

“…2 c . When the substrate ratio was 3, the hydrolysis rate decreased, which may be attributed to substrate inhibition of enzyme at higher oil concentration, besides, the product change the polarity of reaction medium that influenced the active conformation of the lipase 24,25 . The hydrolysis ratio increased with the increasing of enzyme load 0.25-1.00 until a maximum was obtained, and then maintained constant with the increasing of enzyme load Fig.…”

Seed lipases: sources, applications and properties - a review

“…In the enzymatic process, lipases can be used as biocatalysts to promote the exchange of triacylglycerols, showing greater efficiency and leaving no residues (Xu, 2000). However, several studies have indicated that such processes are very expensive due to the high cost of purifying the microbial enzymes (de Castro et al, 2004;Noor et al, 2003). Seed lipases present certain advantages since they do not necessarily have to be purified in order to perform this and other processes (Caro et al, 2000).…”

Saponification ofJatropha curcasSeed Oil: Optimization by D-Optimal Design

“…showed increas in the percentage of FFA, which has the highest value of FFA% at 1.75 M ethanolic KOH (102.2%) and has been chosen for the optimum conditions as can be seen in Table 2. A different observation was reported by other researchers for saponification of various vegetable using C. rugosa lipase [13][14][15]. Increase in enzyme concentration did not give any significant changes in the reaction rate [15].…”
