RESUMEN
O objetivo desse estudo foi avaliar a atividade antimicrobiana e antioxidante de polpa e casca do fruto de uxi. As amostras foram coletadas na cidade de Parintins - AM. Ao pesquisar a atividade antimicrobiana, as concentrações estudadas não apresentaram inibição do desenvolvimento microbiano, assim como para a atividade antioxidante, onde através dos extratos em DMSO, não houve inibição satisfatória do radical livre pelos métodos DPPH, ABTS e para compostos fenólicos totais. O estudo servirá como base para refinamentos direcionados ao estudo dessa temática.
The aim of this study was to evaluate the antimicrobial and antioxidant activity of uxi fruit pulp and rind. The samples were collected in the city of Parintins - AM. When investigating the antimicrobial activity, the studied concentrations did not show inhibition of microbial development, as well as the antioxidant activity, where through DMSO extracts, there was no satisfactory inhibition of free radical by DPPH, ABTS methods and for total phenolic compounds. The study will serve as a basis for refinements directed to the study of this theme.

RESUMEN
Ganoderma lucidum is a medicinal mushroom traditionally used in China against a wide range of diseases such as cancer and also for its prevention. In this work, commercial Chinese strains G. lucidum were compared to wild Brazilian strains aiming to determine the cultivation potential through the use of Jun-Cao. Six formulations were tested and the strains presented good response to the applied method. In general, the mixture between the grass and wood was well suited for the basidiomycetes, contributing to the preparation of substrates that generated better results in Jun Cao.
RESUMEN
The aim of this work was to analyze the Brazilian and Chinese strains of Ganoderma lucidum with molecular RAPD markers. A similarity matrix was elaborated and the RAPD profiles of G. lucidum strains were also compared to two other Ganoderma spp: G. applanatum and G. lipsiense in order to produce genetic similarity among the species. Based on the primers used, it was possible to determine that the Brazilian strains and Chinese strain CC-22 are alike. The method and the primers selection showed to be appropriate for the genetic identification of G. lucidum strains, enabling them to be improved and used in research, as well as in the world market.
