Solvent-free ethyl oleate synthesis mediated by lipase from Candida antarctica B adsorbed on polypropylene powder
(Elsevier Science, 2005-10)
The enzymatic synthesis of ethyl oleate by direct esterification of oleic acid and ethanol in solvent-free media has been studied. Native lipase from Candida antarctica B and Candida antarctica B lipase adsorbed on powdered ...
Biocatalytic benefits of immobilized Fusarium sp. (GFC) lipase from solid state fermentation on free lipase from submerged fermentation
(2020-05-01)
Lipases are promising tools for the synthesis of high value-added compounds and have traditionally been obtained from submerged fermentation processes (SmF). However, solid-state fermentation (SSF) allows linking the ...
Effect of several reaction parameters in the solvent-free ethyl oleate synthesis using Candida rugosa lipase immobilised on polypropylene
(Elsevier Science Sa, 2005-08)
Lipase from Candida rugosa was immobilised onto polypropylene powder by physical adsorption. The immobilised catalyst (CR/PP) was used in the enzymatic synthesis of ethyl oleate in solvent-free medium. The influence of the ...
Ethyl Oleate Synthesis Using Candida rugosa Lipase in a Solvent-Free System. Role of Hydrophobic Interactions
(American Chemical Society, 2004-09)
The solvent-free esterification reaction of a commercial oleic acid and ethanol was selected as the test reaction for Candida rugosa lipase immobilized on polypropylene (PP) at 318 K (initial molar ratio 1:1). Adding of ...
Synthesis and thermophysical properties of two new protic long-chain ionic liquids with the oleate anion
(2010-12)
This work reports the synthesis of 2-hydroxy ethylammonium oleate and bis(2-hydroxy
ethyl)ammonium oleate ionic liquids, which have a long aliphatic chain as well as the study of some of their physical properties, in ...
Immobilization of CALB on activated chitosan: Application to enzymatic synthesis in supercritical and near-critical carbon dioxide
(Elsevier, 2017-03)
Enzymatic synthesis of fatty acid ethyl esters in supercritical and near-critical carbon dioxide using lipase B from Candida antarctica (CALB) immobilized onto chitosan is here investigated. The objective was to evaluate ...
Interfacial activation and bioimprinting of Candida rugosa lipase immobilized on polypropylene: Effect on the enzymatic activity in solvent-free ethyl oleate synthesis
(Elsevier Science Inc, 2005-02)
Lipase from Candida rugosa adsorbed on polypropylene powder (CR/PP) was subjected to activation pre-treatments in order to enhance its activity in solvent-free ethyl oleate synthesis. The lipase activation achieved upon ...
Computational approach to solvent-free synthesis of ethyl oleate using Candida rugosa and Candida antarctica B lipases. I. Interfacial activation and substrate (ethanol, oleic acid) adsorption
(American Chemical Society, 2004-11)
This paper presents the results of a MM2 study of the adsorption of oleic acid and ethanol/water in the tunnel and active-site models of lipases from Candida rugosa and Candida antarctica B. The role of an interface polar/no ...
Synthesis and thermophysical properties of two new protic long-chain ionic liquids with the oleate anion
