Modelling Molecular and Inorganic Data of Amanita ponderosa Mushrooms using Art...
Salvador, Cátia; Martins, M. Rosário; Vicente, Henrique; Neves, José; Arteiro, José; Caldeira, A. TeresaAbstract Wild edible mushrooms Amanita ponderosa Malenc¸on and Heim are very appreciated in gastronomy, with high export potential. This species grows in some microclimates, namely in the southwest of the Iberian Peninsula. The results obtained demonstrate that A. ponderosa mushrooms showed different inorganic composition according to their habitat and the molecular data, obtained by M13-PCR, allowed to disting...
Prediction of bioactive compounds activity against wood contaminant fungi using...
Vicente, Henrique; Roseiro, José; Arteiro, José; Neves, José; Caldeira, A. TeresaBiopesticides based on natural endophytic bacteria to control plant diseases are an ecological alternative to the chemical treatments. Bacillus species produce a wide variety of metabolites with biological activity like iturinic lipopeptides. This work addresses the production of biopesticides based on natural endophytic bacteria, isolated from Quercus suber. Artificial Neural Networks were used to maximize the...
Estudo do Comportamento Ambiental do Azoto em Zonas de Intensa Actividade Pecuária
Garcia, Jorge; Vicente, Henrique; Arteiro, JoséO ciclo do azoto é um dos ciclos biogeoquímicos mais complexos, cuja compreensão apresenta elevada dificuldade, devido às inúmeras formas que o azoto pode tomar. A cada forma corresponde um composto com características próprias e diferentes poten-ciais de reacção e, em consequência, com diversas formas de interacção com o meio, possibilitando aos seres vivos modos distintos de utilização. O azoto, na sua forma ...

Salvador, Cátia; Martins, M. Rosário; Vicente, Henrique; Neves, José; Arteiro, José; Caldeira, A. TeresaAmanita ponderosa are wild mushroom eatable, growing spontaneously in some Mediterranean microclimates, namely in Alentejo and Andaluzia, in the Iberian Peninsula, due to its Mediterranean characteristics. The aim of this study was to evaluate inorganic composition of mycorrhizal Amanita ponderosa collected from different regions of the southwest of the Iberian Peninsula and to access molecular biomarkers usin...
Combined use of LC–ESI-MS and antifungal tests for rapid identification of bioa...
Caldeira, A. Teresa; Arteiro, José; Coelho, Ana; Roseiro, JoséThe strain Bacillus amyloliquefaciens CCMI 1051 used in this study has been isolated in our laboratory from healthy Quercus suber in the south of Portugal and shows high levels of antagonistic properties against filamentous fungi that attack forest products industry due to the production of bioactive peptides. A combined use of LC–ESI-MS and antifungal tests allowed a rapid identification of lipopeptides as act...
Production of Bioactive Compounds Against Wood Contaminant Fungi: An Artificial...
Caldeira, A. Teresa; Roseiro, José; Arteiro, José; Neves, José; Vicente, HenriqueA strain of Bacillus amiloliquefaciens was examined for antifungal activity against wood surface contaminant fungi, blue stain fungi and phytopathogenic fungi. The bacterium was grown in liquid culture media in batch or continuous culture, with different dilution rates, in order to study cell development and the production of metabolites with antifungal activity. The bacterium inhibited the growth of fifteen fu...
An artificial intelligence approach to Bacillus amyloliquefaciens CCMI 1051 cul...
Caldeira, A. Teresa; Arteiro, José; Roseiro, José; Neves, José; Vicente, HenriqueThe combined effect of incubation time (IT) and aspartic acid concentration (AA) on the predicted biomass concentration (BC), Bacillus sporulation (BS) and anti-fungal activity of compounds (AFA) produced by Bacillus amyloliquefaciens CCMI 1051, was studied using Artificial Neural Networks (ANNs). The values predicted by ANN were in good agreement with experimental results, and were better than those obtained w...
A Data Mining Approach to Characterize Amanita ponderosa Mushrooms Using Inorga...
Martins, M. Rosário; Salvador, Cátia; Vicente, Henrique; Neves, José; Arteiro, José; Caldeira, A. TeresaWild eatable mushrooms Amanita ponderosa are very appreciated in gastronomy, showing high export potential. This specie grows spontaneously in some microclimates, namely in the southwest of the Iberian Peninsula. The aim of this study is to find inorganic and molecular markers that allow to characterize the wild A. ponderosa strains collected from different geographical locations in the Iberian Peninsula. Molec...
Aroma Compounds Prevision using Artificial Neural Networks Influence of Newly I...
Caldeira, A. Teresa; Martins, M. Rosário; Cabrita, Maria João; Ambrósio, Cristina; Arteiro, José; Neves, José; Vicente, HenriqueCommercial yeasts strains of Saccharomyces cerevisae are frequently used in white wine production as starters in fermentation process, however, these strains can affect the wine characteristics. The aim of this study was to evaluate the effect of three strains of Saccharomyces spp. (var. 1, 2 and 3) on wine aroma compounds produced in microvinification assays. Microvinification assays were carried out with Viti...
Phylogenetic and Inorganic Profile of Mediterranean Mycorrhizal Amanita pondero...
Salvador, Cátia; Martins, M. Rosário; Vicente, Henrique; Neves, José; Arteiro, José; Caldeira, A. TeresaAmanita ponderosa are wild edible mushrooms, growing in some Mediterranean microclimates, namely in Alentejo and Andaluzia, in the Iberian Peninsula. The nutritional values of these fungi make them highly exportable. Due to the wide diversity of mushrooms in nature, it is essential to differentiate and to identify the various edible species. Mushrooms can accumulate high concentrations of some elements, namely ...
