Abstract:

Tese de Doutoramento em Ciências Veterinárias na especialidade Produção Animal<br>The biodegradation of plant cell wall (PCW) carbohydrates is performed by microbial enzymes that are generally referred to as CAZymes. In animal nutrition, it is now well established that the monogastric animals produce a limited repertoire of CAZymes and as such cannot use efficiently some dietary ingredients that sometimes display antinutritional properties. The dietary supplementation with exogenous CAZymes improves the nutritive value of diets and increases animal’s performance. In particular, this study demo

Abstract:

As feruloil esterases são enzimas relevantes para o processo de hidrólise de materiais lignocelulósicos oriundos de gramíneas. Estas enzimas são tradicionalmente determinadas com o emprego de substratos sintéticos de baixa massa molar. Entretanto, as atividades determinadas a partir desses ensaios não se correlacionam adequadamente com a ação das enzimas em substratos complexos e insolúveis como os materiais lignocelulósicos. Neste sentido, o presente trabalho visou desenvolver um método apropriado para medir a atividade de feruloil esterases utilizando um material lignocelulósico como substra

Abstract:

A parede celular das plantas inclui componentes polissacarídeos complexos, e a sacarificação destes polímeros necessita da ação de conjuntos de enzimas que atuem em sinergia. Enzimas podem formar complexos multi-enzimáticos que possuem mais de uma atividade catalítica derivada de domínios distintos de uma mesma cadeia polipeptídica. O objetivo deste trabalho foi construir uma enzima bifuncional com os domínios catalíticos: acetilxilano esterase (Axe) e feruloil esterase (Fae) para desconstrução de material lignocelulósico de cana-de-açúcar. Para isso, dois diferentes domínios catalíticos: acet

Abstract:

Feruloyl esterases (FAEs, EC 3.1.1.73) represent a subclass of carboxylic acid esterases that under normal conditions catalyze the hydrolysis of the ester bond between hydroxycinnamic acids (ferulic acid, sinapic acid, caffeic acid, p-coumaric acid) and arabinose residues in plant cell walls. Based on their specificity towards monoferulates and diferulates, substitutions on the phenolic ring and on their amino acid sequence identity, they have been classified into four types (A-D). The use of FAEs as accessory enzymes for the degradation of lignocellulosic biomass and their synergism with othe

Abstract:

Feruloyl esterases (E.C. 3.1.1.73), a subclass of the carboxylic acid esterases (E.C. 3.1.1.1), are able to hydrolyse the ester bond between the hydroxycinnamic acids and sugars present in the plant cell walls, and have been classified as Types A or B based on their substrate specificity for aromatic moieties. They constitute an interesting group of enzymes that have the potential for use over a broad range of applications in the agri-food industries. In order to expand the range of available enzymes, we have examined the production of feruloyl esterases by the filamentous fungi Talaromyces sl

A further objective was to investigate a possible co-operative effect with other selected lignocellulolytic enzymes on substrates relevant to industry. In a comprehensive review, feruloyl esterases from various micro-organisms were compared both functionally and with regard to their primary structure, where applicable.

Abstract:

Growth of <i>Penicillium pinophilum</i> in solid state culture on oat straw and wheat bran mixtures was found suitable for the production of xylan-degrading enzymes. An extracellular phenolic acid esterase and a xylanase were purified to homogeneity by a combination of anion-exchange and hydrophobic interaction chromatography. The physicochemical properties and the mode of action of the esterase on various xylan polysaccharides were investigated. The esterase had an apparent molecular mass of 57 kDa by SDS-PAGE and an isoelectric pH of 4.6. The enzyme released ferulic and ρ-coumaric acid from

MetS is a cluster of metabolic disturbances, including abdominal obesity, atherogenic dyslipidemia, elevated blood pressure, insulin resistance and the presence of a proinflammatory and prothrombotic state. Currently, there is no successful therapeutic intervention for the prevention and treatment of this disorder. Chronic systemic inflammation and hypercholesterolemia are two important therapeutic targets of MetS. The goal of this work is to develop a novel microencapsulated ferulic acid-producing pro

Les féruloyl estérases sont responsables de l’hydrolyse de liaisons ester entre l’acide férulique et les chaînes de xylane ou de pectine. En clivant ces liaisons, elles favorisent une dégradation complète de la paroi végétale. L'importance de ces enzymes nous a conduit à rechercher si D.

Abstract:

Lignocellulosic biomass is an abundant renewable resource targeted for biofuel production. Cellulose and hemicellulose from biomass both contain fermentable sugars and other moieties that can be converted to biofuels or other commodity chemicals. Enzymatic hydrolysis of these biopolymers is a critical step in the liberation of sugars for fermentation into desired products. In nature, anaerobic microbes produce protein nanostructures called cellulosomes that efficiently degrade cellulose substrates by combining multiple enzyme activities onto a scaffolding protein.
