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 Carlos; 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...
AVALIAÇÃO TOXICOLÓGICA E EFEITO HEPATOPROTECTOR DE COMPLEXOS PROTEÍNA-POLISSACÁ...
Ribeiro, R; Caldeira, A Teresa; Candeias, M F; Sampaio, J; Karmali, A; Arteiro, José; Martins, M RosárioAs propriedades medicinais de vários cogumelos são amplamente conhecidas, no entanto, apenas nas últimas décadas, foi possível isolar e caracterizar alguns metabolitos biologicamente activos. Os efeitos terapêuticos de alguns fungos, tais como o Trametes versicolor, são maioritariamente atribuídos ao seu conteúdo em polissacáridos. O objectivo deste trabalho é estudar as propriedades hepatoprotectoras dos compl...
A Distributed Web-based Water Quality Diagnosis and Simulation System in Lakes ...
Neves, José; Machado, José; Cortez, Paulo; Arteiro, José; Vicente, HenriqueOver the last few years Connectionistic Networks, also referred to as Parallel Distributed Processing Systems or Neural Networks (NNs), have been in the center of a renewed and increasing interest. Indeed, the application of NNs in different arenas such as forecasting, machine vision or speech recognition are examples of their widely use in problem solving. The advent of environments for creating and using soft...

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 using...
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 ...
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 ...
Ecological Mining - A Case Study on Dam Water Quality
Santos, Manuel F.; Cortez, Paulo; Quintela, Hélder; Neves, José; Vicente, Henrique; Arteiro, JoséThe automatic assessment of barrage water quality is very restricted due to the distances, the number of biochemical parameters to be considered and the financial resources spent to obtain their values. To this scenario should be added the latency times between the sampling moment and the outcome of the laboratory analyses. Although the idea of considering sensors for remote acquisition of data is not new, ther...
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...
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.
