| Summary: | The ability of Candida cylindracea lipase produced using palm oil mill effluent (POME)
as a basal medium to catal yze the esterification reaction for butyl butyrate formation was investi-gated. Butyric acid and n-butanol were used as substrates at different molar ratios. Different con-version yields were observed according to the affinity of the produced lipase toward the substrates.
The n -butanol to butyric acid molar ratio of 8 and lipase concentration of 75 U/mg gave the highest
butyl butyrate formation of 63.33% based on the statistical optimization using face centered central
composite design (FCCCD) after 12 h reaction. The esterification potential of the POME based
lipase when compared with the commercial lipase from the same strain using the optimum levels
was found to show a similar pattern. It can be concluded therefore that the produced lipase pos-sesses appropriate characteristics to be used as a biocatalyst in the esterification reactions for butyl
butyrate formation |
