Item Environmental impact of pollutants and the potential contribution to phytoremediation(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) SILVA, Simone da; LEITE, Jandecy CabralThis chapter revisited an experiment that evaluated elicitors for the germination of Vigna unguiculata (Cowpea Beans): the plant extract of Euphorbia tirucalli, the ultra-diluted and dynamized solution of Sulfur 5CH, and the two in combination. In 2017, significant seed engorgement and ammonia-like odor exudation suggested involvement of the sodium/potassium pump, thiol group detoxifying enzymes, and nitrogenous oxidative stress pathways. Given recent literature linking thiol groups to mercury phytoremediation, the study discusses E. tirucalli as a potential hyperaccumulator, considering mechanisms such as phytoextraction and phytovolatilization of pollutants.Item Investigation of the antifungal action of natural products on seeds of Euterpe oleraceae: Bioproduct Potential(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) SILVA, Simone da; LEITE, Jandecy CabralAçaí seeds (Euterpe oleraceae) are used in handicrafts by urban indigenous Sateré-Mawé in Rio de Janeiro, Brazil. However, fungal contamination compromises their conservation, leading to losses of approximately 47% of the purchased seeds. This study tested the antifungal activity of aqueous extracts from Bixa orellana (Annatto), Punica granatum (Pomegranate), Tagetes erecta (Marigold), and Euphorbia tirucalli (Firestick) on açaí seeds. Only E. tirucalli showed significant antifungal action (21.75%) at the tested concentration, indicating potential for seed preservation. Based on these findings, further trials will be conducted within the One Health perspective.
