Kinetic Study of Ethyl Hexanoate Synthesis Using Surface Coated Lipase from Candida Rugosa
Kinetics of lipase-catalyzed esterification of hexanoic acid and ethyl alcohol using the solvent-free system, surface coated lipase from Candida rugosa, had been studied. The effect of various parameters such as reaction time, reaction temperature, reaction kinetics, water removal and feasibility of solvent-free system had been focused. Candida Rugosa lipase was more effective than other li...
متن کاملSynthesis and Characteristics of Mesoporous Sol-gels for Lipase Immobilization
Enzyme cost is the major problem for industrial scale application. Immobilization is a promising approach to moderate the enzyme cost factor and increase its stability and activity. In this study, sol-gel method was used to prepare the immobilization platform and entrapped lipase as one of the most used enzyme in dairy processing, cosmetics and pharmaceutical industries. Lipase from Candida rug...
متن کامل[Expression of Candida antarctica lipase B on yeast surface and synthesis of ethyl hexanoate catalyzed by CALB].
Short-chain esters play a significant role in the food industry as flavor and aroma constituents. Candida antarctica lipase B (CALB) is one of the most effective catalysts for organic synthesis. We constructed a CALB-displaying yeast whole-cell biocatalyst and applied it to esterification from caproic acid and ethanol. CALB was fused with the alpha-agglutinin C-terminal and the signal peptide o...
متن کاملOptimization of Lipase Immobilization
Pseudomonas aeruginosa BBRC-10036 was used for lipase production. The organism secreted the enzyme extracellulary. In order to purify the enzyme, precipitation was done first, and then this lipase has been purified by Ion exchange Chromatography leading to 2.3-fold purification and 11.47% recovery. Lipase from P.aeruginosa was entrapped into Ca-alginate gel beads and effect of independent varia...
متن کاملLow-temperature lipase from psychrotrophic Pseudomonas sp. strain KB700A.
We have previously reported that a psychrotrophic bacterium, Pseudomonas sp. strain KB700A, which displays sigmoidal growth even at -5 degrees C, produced a lipase. A genomic DNA library of strain KB700A was introduced into Escherichia coli TG1, and screening on tributyrin-containing agar plates led to the isolation of the lipase gene. Sequence analysis revealed an open reading frame (KB-lip) c...
