RESUMO -(Plantas medicinais usadas pelas populações indígenas Kaiowá e Guarani na Reserva de Caarapó, Mato Grosso do Sul, Brasil). Estudo etnobotânico realizado com a população indígena Kaiowá/Guarani na Reserva de Caarapó (Mato Grosso do Sul, Brasil) mostrou que 34 espécies vegetais, distribuídas em 22 famílias, têm propriedades medicinais e são utilizadas para o tratamento de diversas patologias. As informações obtidas foram: nome local em Português e em Guarani, indicações terapêuticas, preparação e a parte da planta utilizada. As principais plantas medicinais são usadas pela população indígena no tratamento de gripes e resfriados, dores abdominais, febres, reumatismos e para o tratamento de feridas. Palavras-chave: população Kaiowá/Guarani, etnobotânica, plantas medicinais ABSTRACT -(Medicinal plants used by the Kaiowá and Guarani indigenous populations in the CaarapóReserve, Mato Grosso do Sul, Brazil). This ethnobotanical survey carried out with the Kaiowá and Guarani populations in the Caarapó Reserve (Mato Grosso do Sul, Brazil) showed that 34 plant species of 22 families with medicinal properties, are used for treating diverse pathologies. Local names in Portuguese and Guarani are provided, along with therapeutic indications, modes of preparation, and a description of the plant parts used. These folk-medicine plants have been mostly used for the treatment of influenza, abdominal pain, fever and rheumatism, and for wound healing.

Fermentation parameters for phytase production in column-type bioreactor were monitored using a new data acquisition system. There are a number of studies reporting phytase production in flasks, but a lack of data about microorganism respiration behaviour during phytase production using column bioreactor. The objectives of this work were the monitoration of fermentation parameters during phytase production and its relation with fungal growth and forced air. Phytase production by A. niger FS3 increased with forced air. The O(2) consumption and CO(2) production during solid-state fermentation were monitored by sensors (in the bottom and top of the columns) linked to controllers, recorded by acquisition software and processed by Fersol2(®) software tool. Phytase synthesis was associated with fungal growth. Therefore, phytase could be used to estimate FS3 biomass formed in citric pulp degradation.

The regeneration of transgenic plants of Eucalypt is the largest difficulty for the genetic transformation of this genus; in addition a low rate of transformed plants is reached. The aim of this research was to evaluate acetosyringone (3',5'-Dimethoxy-4'-hydroxyacetophenone) on the co-culture medium during genetic transformation of shoot tips of Eucalyptus saligna via Agrobacterium tumefaciens and to promote the explants selection supposedly transformed. Shoot tip from multiple shoots was used as explants. These explants were pre-cultured during two days before the transformation. Strain EHA105 of A. tumefaciens harboring the plasmid pBI121 was used. The treatments were: 0 and 100 μM acetosyringone added to the co-culture, after co-culture the explants were cultured in multiplication medium supplemented with 250 mg.L-1 Cefotaxime® and each sub-culture the kanamycin levels were increased from 50 to 150 mg.L-1. The transient expression of the uidA gene in shoot tips was evaluated after the end of the co-culture (fifth day) and after seven days of culture on medium containing kanamycin. The presence of 100 µM acetosyringone at the co-culture of shoot tips of Eucalyptus saligna promoted higher transient expression of the uidA gene and retards toxic effects caused by kanamycin.

<p class="Default">As potencialidades de utilização de métodos alternativos no controle de doenças de plantas são incessantemente estudadas e avaliadas por vários pesquisadores no mundo inteiro, com o objetivo de minimizar o impacto ambiental através da utilização de produtos naturais. Este trabalho teve como objetivo traçar o perfil fitoquímico preliminar verificando a atividade antimicrobiana <em>in vitro</em> do extrato hidroalcóolico de <em>Allium sativum</em> L. contra <em>Bipolaris </em>spp., <em>Curvularia lunata</em> e <em>Fusarium subglutinans</em> através do mecanismo de pulverização na Torre de Potter. Observou-se na análise fitoquímica a presença de taninos hidrolisáveis, saponinas e flavonóides. O extrato possuiu atividade antimicrobiana sobre todos os fungos fitopatogênicos testados, com destaque para os fungos <em>Curvularia lunata</em> e <em>Fusarium subglutinans </em>nas concentrações de 40 a 50%, no entanto, o fungo <em>Bipolaris </em>spp. mostrou-se mais resistente com sensibilidade apenas na concentração máxima de 50%.</p><p align="center"><strong><em>Antimicrobial activity and analysis phytochemical preliminary extract vegetable garlic in fungi phytopathogenic control</em></strong></p><p><strong>Abstract</strong><strong>: </strong>The potential use of alternative methods in plant disease control are constantly studied and evaluated by several researchers worldwide with the aim of minimizing the environmental impact through the use of natural products. This study aimed to trace the preliminary phytochemical profile and check the <em>in vitro</em> antimicrobial activity of garlic hydroalcoholic extract in different concentrations against <em>Bipolaris</em> spp., <em>Curvularia lunata</em> and <em>Fusarium subglutinans</em> through the spray mechanism in the Potter Tower. It was observed in the presence of phytochemical analysis hydrolysable tannins, saponins and flavonoids. The extract possessed antimicrobial activity against all pathogenic fungi tested, especially the fungi <em>Curvularia</em> <em>lunata</em> and <em>Fusarium</em> <em>subglutinans</em> in concentrations of 40 to 50%, however, the fungus <em>Bipolaris</em> spp. it proved to be tougher with sensitivity only at the maximum concentration of 50%.</p><p><strong><br /></strong></p>
