Performance of different immobilized lipases in palm oil biodiesel synthesis
(UNIV ESTADUAL MARINGA, PRO-REITORIA PESQUISA POS-GRADUACAO, 2011)
Performance of different immobilized lipases in palm oil biodiesel synthesis. Optimized conditions for palm oil and ethanol enzymatic biodiesel synthesis were determined with different immobilized lipases SiO(2)-PVA-immobilized ...
Chitosan-immobilized lipases for the catalysis of fatty acid esterifications
(Elsevier Science Inc, 2007-03)
Lipases from Candida rugosa, Pseudomonas fluorescens and Candida antarctica B were immobilized onto chitosan and glutaraldehyde-pretreated chitosan powders. The prepared biocatalysts were assayed in the direct esterification ...
Biodiesel production from alternative raw materials using a heterogeneous low ordered biosilicified enzyme as biocatalyst
(BioMed Central, 2021-03-15)
Background: Cumulative reported evidence has indicated that renewable feedstocks are a promising alternative source to fossil platforms for the production of fuels and chemicals. In that regard, the development of new, ...
Imobilização de lipases pela técnica CLEA para síntese de biodiesel em reator de fluxo em vórtice
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2017-10-30)
Due to the heterogeneity of the vegetable oils used in the synthesis of biodiesel, they can be transformed more quickly using a mixture consisting of lipases with different activities and specificities instead of single ...
Immobilization and stabilization of microbial lipases by multipoint covalent attachment on aldehyde-resin affinity: Application of the biocatalysts in biodiesel synthesis
(ELSEVIER SCIENCE BV, 2011)
Microbial lipase preparations from Thermomyces lanuginosus (TLL) and Pseudomonas fluorescens (PFL) were immobilized by multipoint covalent attachment on Toyopearl AF-amino-650M resin and the most active and thermal stable ...
Síntese enzimática de ésteres catalisada por lipases imobilizadas em diferentes suportes
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2013-03-22)
Lipases are enzymes of great biotechnological relevance. Besides its natural function (hydrolysis of triglycerides), they are capable of catalyzing regio- and enantioselective hydrolysis and synthesis of numerous esters. ...
Estudo da influência de nanopartículas de ouro na atividade de lipase de Pseudomonas fluorescens imobilizada em nanopartículas superparamagnéticas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2020-02-19)
The growing interest in the application of biocatalysts in several industrial sectors made the enzymatic immobilization stand out among the possible strategies to enable the use of these catalysts. This strategy has the ...
Evaluation of immobilized lipases on poly-hydroxybutyrate beads to catalyze biodiesel synthesis
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Five microbial lipase preparations from several sources were immobilized by hydrophobic adsorption on small or large poly-hydroxybutyrate (PHB) beads and the effect of the support particle size on the biocatalyst activity ...
