Molecular evaluation of some Amanita ponderosa and fungal strains living in ass...
Salvador, C; Martins, M Rosário; Arteiro, J M; Caldeira, A TeresaAmanita ponderosa are wild edible mushrooms that grow only in some microclimates, particularly those in the southwestern part of the Iberian Peninsula. Due to the vast diversity of mushrooms in nature, as well as nutrient variability, which is highly dependent on soil type and environmental conditions, it is essential to be able to characterize fungal microbiota that lives in association with mushrooms and to d...
Culturas de fungos basidiomicetos em resíduos agroindustriais para produção de ...
Salvador, C; Candeias, M F; Martins, M Rosário; Caldeira, A TeresaSeveral agro-industrial residues (beet wastes, tomato pomace, sunflower straw, wheat straw and rice peel) were used to develop liquid cultures of Basidiomycetes, allowing the production of innovative protein-polysaccharide compounds (Arteiro, et al. 2012, Salvador, et al. 2012). These complexes show no toxicity in Artemia salina after 24 hours of incubation and caused no hepatotoxicity in in vivo assays using W...
Protein–polysaccharides of Trametes versicolor: production
Arteiro, J M; Martins, M R; Salvador, C; Candeias, M F; Karmali, A; Caldeira, A TeresaAbstract Extracellular- (E-PPS) and intracellular-protein– polysaccharides (I-PPS) complexes were produced by Trametes versicolor in submerged cultures with different carbon sources. The highest extracellular-(EPS) and intracellular- polysaccharide (IPS) concentration in the complexes was obtained with tomato pomace culture. DPPH radical scavenging for E-PPS and I-PPS produced by liter of culture was equivallen...
Immobilization of amidase in polymeric matrixes
Vieira, R; Quaresma, R; Salvador, C; Martins, M; Arteiro, J; Castanheiro, J; Caldeira, AThe catalytic activity of amidase immobilized in alginate and PVA matrixes were studied in the acetamide hydrolyse. It was observed that the recovery (immobilized cells activity / free cells activity x100) of PVA membrane (20% w/w)+ cells is highest.
Actividade biológica de complexos proteína-polissacárido produzidos em culturas...
Caldeira, A T; Martins, M R; Candeias, MF; Salvador, C; Heber, M; Semedo, C; Karmali, A; Arteiro, J MTrametes versicolor é um fungo utilizado como fonte alimentar e com propriedades medicinais conhecidas [1,2]. Em trabalhos anteriores avaliámos a produtividade de complexos proteína-polissacárido intra e extracelular (IPS e EPS) em culturas de T. versicolor utilizando várias fontes de carbono. Concluímos ser esta produção máxima no 14º dia de cultura e ser o repiso de tomate a fonte de carbono mais eficaz na qu...
Molecular biomarkers and inorganic profile to characterize Amanita ponderosa mu...
Martins, M R; Salvador, C; Arteiro, J M; Caldeira, A TAmanita ponderosa are wild mushroom eatable, very appreciated in gastronomy, with high exportation potential, that grow spontaneously in some microclimates, particularly in Alentejo and Andalusia. Due to the symbiotic relation, mushrooms can accumulate high concentrations of some metals, consequently is important to estimate the trace metal contents to assessing exposure risks. Although some species of genera A...
