Item Cogumelos de ocorrência espontânea como produtos florestais em Bonito-PE(2019-11-25) Lima, Felipe Tavares; Oliveira, Lourinalda Luiza Dantas da Silva Selva de; Lima, Vitor Xavier de; http://lattes.cnpq.br/5855288559616188; http://lattes.cnpq.br/7013867423178814; http://lattes.cnpq.br/0157704339343186Although essential for maintaining life on earth, little is known about fungi. It is estimated that only 10% of macrofungus species are known. The use of mushrooms by human populations dates back thousands of years and continues to this day in over 80 countries. In Brazil, there is little record of use by traditional populations, except for some Amazonian peoples. Today, the demand for this resource has increased due to its nutritional and medicinal properties. The world mushroom market moves 43 billion dollars a year, however, the country has no relevant production in this sector. This is partly due to the high cost of technology to enable the cultivation of species not adapted to the local climate. The exploitation of spontaneously occurring species would lower production costs and could make the sector accessible to family farmers, who produce much of the food in the country, even with limited land available, benefiting them with numerous socio-economic and environmental benefits from diversification. of production. However, little is known about local strains, requiring nutritional and bioactive metabolite assays. The city of Bonito stands out for its policy of protecting forest remnants and for the presence of a solidarity economy network in family agriculture in agroecological transition. The objective of this work was to verify the spontaneous occurrence and potential for use of food and medicinal mushrooms in areas easily accessible by family farmers from Bonito - Pernambuco. For this, a diagnosis was initially made about the perception and openness for the introduction of mushrooms in the productive chains of both family farmers in agroecological transition as well as traditional ones. Then, species were collected, identified and listed in forest fragments and other areas easily accessible by farmers. In the species found was made mycochemical prospecting and nutritional analysis. Twelve species were listed in total, of which eight are cited as edible and medicinal, two as medicinal only and two as edible only. These have been shown to have the metabolite groups typically associated with bioactivity. Three of the mushrooms had their protein, lipid, carbohydrate and ash content quantified, presenting common levels for mushrooms. This has expanded the little known about edible and medicinal mushrooms in the country and especially in the city of Bonito, and it is hoped that the work can be the germ for further studies and for creating new opportunities for income generation in Bonito. coexistence with the forests from these, not only for the city and the farmers where and with whom the work was done, but for all those who live with this underexplored forest resource.Item Abordagem metabonômica no estudo da toxicidade de plantas da família convolvulaceae contendo swainsonina e calisteginas(2019-12-13) Nascimento, Ana Lessa Oliveira do; Souza, Francisco de Assis Leite; http://lattes.cnpq.br/5304030174444186; http://lattes.cnpq.br/1434642356384009The Compulsory Supervised Internship (CSI) was held at the Parisian Institute of Science and Technology of Life and Environment (AgroParisTech). The institute, considered the most important in France on life science research and development, is divided into eight centers across the country, two of which located in Paris, Avenue du Maine Center and Claude Bernard Center, located in the 5th arrondissement of Paris. There are 11 Research Units composed of one or more laboratories and teams of teachers, technicians, doctoral students and master's students, these units can be mixed (those under the supervision of more than one entity) or their own (supervised by the institute itself). More precisely, the CSI was conducted at the Mixed Research Unit (UMR) Systemic Modeling Applied to Ruminants (MoSar), which is administered by AgroParisTech and the National Institute for Agronomic Research (INRA), which is under the Ministry of Research and Ministry of Agriculture. The aim of the internship was to start the formation in metabolomics, showing how the methodology can contribute to the study of plant poisoning, in this case to the group containing swainsonine and / or calystegines, that affect farm animals in Brazil, and to produce a literature review on the subject of the internship. Metabonomics is an important research tool that allows investigating the metabolic pathways affected in a toxicological process. When performed properly and periodically throughout an experiment and with pre-designed protocols, conceived from a biological problem, it is possible to follow the evolution of the intoxication process, identify useful markers for the establishment of pathogenesis and diagnosis, and in the case of global metabolic, that is, one can make discoveries that had not been raised in the initial biological questioning. This is possible thanks to the holistic characteristic of the technique, which makes it possible to visualize and quantify even the most subtle variations in metabolites concentrations. Plants containing swainsonine and calystegines are responsible for numerous cases of animal poisoning in Brazil, mainly goats in the Northeast due to factors related to extensive and semi-extensive breeding, these substances cause a severe neurological syndrome that can lead from decreased productivity to even death of animals, which can cause economic loss to producers, who often have animals as the main source of income, making it very important to clarify the mechanisms involved in establishing this disease in order to find solutions to the problem.
