Journal ArticleDOI
Directed immobilization of CGTase: The effect of the enzyme orientation on the enzyme activity and its use in packed-bed reactor for continuous production of cyclodextrins
Jéssie da Natividade Schöffer,Carla Roberta Matte,Douglas Santana Charqueiro,Eliana Weber de Menezes,Tania Maria Haas Costa,Edilson Valmir Benvenutti,Rafael C. Rodrigues,Plinho Francisco Hertz +7 more
TL;DR: Two different approaches were assessed in order to direct the immobilization of a cyclodextrin glycosyltransferase on functionalized silica support, one by amino groups using glutaraldehyde activation and other by disulfide bond through the Cys on the enzyme surface (Si-SH-CGTase).
Journal ArticleDOI
Effects of oxygen volumetric mass transfer coefficient and pH on lipase production by Staphylococcus warneri EX17
TL;DR: The relationship between cell growth and lipase production was found to be associated with growth by the Luedeking-Piret model.
Journal ArticleDOI

Journal ArticleDOI
Ultrasound-assisted transesterification of soybean oil using combi-lipase biocatalysts
Vitória Olave de Freitas,Carla Roberta Matte,Jakeline K. Poppe,Rafael C. Rodrigues,Marco Antônio Záchia Ayub +4 more
TL;DR: In this paper, the authors applied ultrasonic technology for the transesterification of soybean oil catalyzed by a mixture of lipases (combi-lipase: 75 % Novozym 435, 10 % Lipozyme TL-IM, and 15 % RM-IM), verifying the effects of ultrasonic amplitude, pulse conditions, the ethanol:oil molar ratio, enzyme concentration, and the influence of solvent (tert-butanol on the reaction.
Journal ArticleDOI
Microbial Enzymes as Substitutes of Chemical Additives in Baking Wheat Flour—Part II: Combined Effects of Nine Enzymes on Dough Rheology
TL;DR: In this article, the combined effects of nine commercial enzymes were studied on the rheological properties of dough wheat flour, and it was demonstrated that it is possible to perform the complete substitution of chemical oxidants by enzymes in order to adequately improve rheology parameters of a weak flour, making it suitable for a bakery.
