Rapid and high yields of synthesis of butyl acetate catalyzed by Novozym 435: Reaction optimization by response surface methodology
Andréa B. Martins,Natália G. Graebin,André Soibelmann Glock Lorenzoni,Roberto Fernandez-Lafuente,Marco Antônio Záchia Ayub,Rafael C. Rodrigues +5 more
TL;DR: In this paper, the authors described the optimization of the esterification reaction of butyl acetate synthesis catalyzed by Candida antarctica lipase B (Novozym 435).
Journal ArticleDOI
Immobilization of lipase B from Candida antarctica on porous styrene-divinylbenzene beads improves butyl acetate synthesis.
Natália G. Graebin,Andréa B. Martins,André Soibelmann Glock Lorenzoni,Cristina Garcia-Galan,Roberto Fernandez-Lafuente,Marco Antônio Záchia Ayub,Rafael C. Rodrigues +6 more
TL;DR: MCI‐CALB has shown to be a very promising biocatalyst for the esterification of small‐molecule acids and alcohols and could be reused for six consecutive cycles without any washings and keeping around 70% of its initial activity.
Journal ArticleDOI
Immobilization and stabilization of different β-glucosidases using the glutaraldehyde chemistry: Optimal protocol depends on the enzyme
Diandra de Andrades,Natália G. Graebin,Marina Kimiko Kadowaki,Marco Antônio Záchia Ayub,Roberto Fernandez-Lafuente,Rafael C. Rodrigues +5 more
TL;DR: The enzyme from A. niger, immobilized on MANAE-agarose at pH 9 and subsequently treated with glutaraldehyde, produced the highest stabilization (approximately 560 times more stable than soluble enzyme at 60 °C).
Journal ArticleDOI
Immobilization of Glycoside Hydrolase Families GH1, GH13, and GH70: State of the Art and Perspectives
Natália G. Graebin,Jéssie da Natividade Schöffer,Diandra de Andrades,Plinho Francisco Hertz,Marco Antônio Záchia Ayub,Rafael C. Rodrigues +5 more
TL;DR: The state of the art of enzyme immobilization of families GH1, GH13, and GH70 is reviewed, with special attention on the enzymes β-glucosidase, α-amylase, cyclodextrin glycosyltransferase, and dextransucrase.
Journal ArticleDOI
Optimization of pineapple flavour synthesis by esterification catalysed by immobilized lipase from Rhizomucor miehei
André Soibelmann Glock Lorenzoni,Natália G. Graebin,Andréa B. Martins,Roberto Fernandez-Lafuente,Marco Antônio Záchia Ayub,Rafael C. Rodrigues +5 more
TL;DR: In this article, the synthesis of pineapple flavour (butyl butyrate) catalysed by lipase from Rhizomucor miehei has been optimized using central composite design and response surface methodology.
