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...
Protein-bound polysaccharides from Amanita ponderosa cultures: characterisation...
Nunes, Patricia; Salvador, Catia; Arteiro, J. M.; Martins, M. Rosário; Caldeira, A. TeresaIn recent years, protein-polysaccharide complexes extracted from mushrooms have received great attention from the scientific community, due to their medicinal properties, namely antioxidant, antitumor, antimicrobial, immunomodulatory, antiatherogenic and hypoglycaemic properties [1, 2]. The southern of Portugal, due to its Mediterranean climate and flora diversity, is a region with a high prevalence of wild edi...
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...
Pleurotus ostreatus in the biological treatment of olive oil mill wastes
Antunes, D; Pereira, A; Caldeira, A Teresa; Marques sa Silva, J R; Arteiro, J MOlive oil mill wastes (OMW) constitute an important environmental problem due to the large amount of phenolic compounds and the high toxicity they present. The aim of this work was to characterize the OMW and to develop a biological treatment that promotes a new approach of OMW management. P. ostreatus cultures performed with OMW showed a fungal biomass enhancement as well as medium clarification. A 50%-74% tot...
Redução de compostos fenólicos de resíduos de lagares de azeite utilizando cult...
Pereira, A.; Antunes, D.; Caldeira, A.Teresa; Marques da Silva, José Rafael; Arteiro, J. M.In this study, C. versicolor cultures were performed during 20 days with different RLA (olive mill wastes)subtracts, 50%, 75% and 100%. During this assay, samples were collected in regular time intervals, cell growth were evaluated and broth decolorization was observed. The organic matter and total phenolic compounds level in the culture broth showed a decrease in all RLA ratios. 50% and 75% RLA presented high ...
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. Rosário; Salvador, Cátia; Arteiro, J. M.; Caldeira, A. TeresaAmanita ponderosa strains are wild mushroom eatable species, very appreciated in gastronomy, with a high exportation potential that grow spontaneously in some microclimates, particularly in Alentejo and Andaluzia. Additionally, its mineral and organic composition, depend on the fungal strain and their ecosystem. Moreover, due to symbiotic relation between mushrooms and some plants in its habitats, mushrooms can...

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...
