Simplified, high yielding extraction of xylan/xylo-oligosaccharides from palmar...
Coelho, Diogo; Costa, Diogo Félix; Barroca, Mário; Cunha, Sara Alexandra; Pintado, Maria Manuela; Abreu, Helena; Martins, Margarida; Collins, TonyThe complex plant cell wall heteropolysaccharide xylan, and its breakdown products xylo-oligosaccharides and xylose, are value-added compounds with a plethora of potential applications in diverse areas. They are nonetheless currently poorly exploited, with a major bottleneck being the unavailability of efficient, low-cost, high-yield production processes. The major objective of the present study is to identify ...

Integrated transcriptomics and proteomics analysis reveals muscle metabolism ef...
Ribeiro, David Miguel; Coelho, Diogo; Costa, Mónica; Carvalho, Daniela; Leclercq, Céline C.; Renaut, Jenny; Freire, João; Almeida, AndréSeaweeds, including the green Ulva lactuca, can potentially reduce competition between feed, food, and fuel. They can also contribute to the improved development of weaned piglets. However, their indigestible polysaccharides of the cell wall pose a challenge. This can be addressed through carbohydrase supplementation, such as the recombinant ulvan lyase. The objective of our study was to assess the muscle metab...
roteiro para a gestão dos fluxos gerados na atividade agropecuária
Nunes, Rui; Ligeiro, Carolina; Menino, Regina; Branco, Maria Amélia Castelo; Duarte, Elizabeth D'Almeida; Fragoso, Rita do Amaral; Silva, InêsA grande dimensão dos custos económicos e ambientais decorrente da intensificação dos sistemas agrícolas, pecuários e agroindustriais, torna imperiosa a procura de soluções que valorizem os seus efluentes e coprodutos, visando tanto a redução da sua toxicidade como o desenvolvimento sustentável de novos processos e de novos produtos. No Âmbito do Programa de Desenvolvimento Rural 2020, Medida 1. Promoção para a...
Effect of Dietary Laminaria digitata with Carbohydrases on Broiler Production P...
Costa, Mónica M.; Pestana, José M.; Osório, Diogo; Alfaia, Cristina M.; Martins, Cátia F.; Mourato, Miguel; Gueifão, Sandra; Rego, Andreia M.Simple Summary: Seaweeds represent promising alternatives to unsustainable conventional feed sources, such as cereals, incorporated in poultry diets. Brown macroalgae (e.g., Laminaria digitata) correspond to the largest cultured algal biomass worldwide and are rich in bioactive polysaccharides, minerals, and antioxidant pigments. However, their utilization as feed ingredients is limited due to the presence of a...
Influence of Feeding Weaned Piglets with Laminaria digitata on the Quality and ...
Ribeiro, David; Alfaia, Cristina; Pestana, José; Carvalho, Daniela; Costa, Mónica; Martins, Cátia; Lemos, José; Mourato, Miguel; Gueifão, SandraLaminaria digitata is a novel feedstuff that can be used in pig diets to replace conventional feedstuffs. However, its resilient cell wall can prevent the monogastric digestive system from accessing intracellular nutrients. Carbohydrate-active enzyme (CAZyme) supplementation is a putative solution for this problem, degrading the cell wall during digestion. The objective of this work was to evaluate the effect o...
Effect of dietary incorporation of Chlorella vulgaris and CAZyme supplementatio...
Ribeiro, David M.; Coelho, Diogo; Osório, Hugo; Martins, Cátia; Freire, João; Almeida, João; Moreira, Olga; Almeida, André; Prates, José A.M.The combination of several factors, including an increase in world population and living standards in developing countries and world dependency on conventional crop imports drive a search for alternative feedstuffs for poultry and pig diets. This would reduce the environmental impact associated with the foreseeable increase in the demand for animal products. One of such alternatives are microalgae, a diverse gr...
Impact of Chlorella vulgaris as feed ingredient and carbohydrases on the health...
Coelho, Diogo; Alfaia, Cristina; Lopes, Paula Alexandra; Pestana, José M.; Costa, Monica M.; Pinto, Rui M.; Almeida, Joao M.; Moreira, OlgaThe implication of high dietary level of Chlorella vulgaris, individually and supplemented with two carbohydrase mixtures, on pigs' health and liver metabolism was assessed in this study. Forty crossbred (Large White × Landrace sows crossed with Pietrain boars) entire male pigs were randomly allocated to the following feeding treatments (n = 10): cereal-soybean meal basal diet (control); basal diet with 5% C. v...
Improving the nutritional value of microalgae for feeding pigs through the use ...
Coelho, DiogoThe pig industry will face new challenges due to the increase demand for pork, concerning the negative environmental impact and the low content in the beneficial n-3 polyunsaturated fatty acids (PUFA) of pork. Microalgae exhibit a well-balanced nutritional composition, including in n-3 PUFA, and its production has a low environmental impact. Thus, microalgae could be a suitable alternative to traditional feedst...
