1. ENDOPHYTIC FUNGI COMMUNITY IN Eremanthus erythropappus TREE FROM ANTHROPOGENIC AND NATURAL AREAS OF MINAS GERAIS
ABSTRACT It is know that many plants live in symbiosis with microorganisms that can be found on their interior, the endophytes. Environment and tissue type are modulating factors of this community, in which most of these microorganisms produce important antimicrobial molecules and they may be powerful biocontrol agents in agriculture. Thus, the aim of this s

2. Anti-Candida and anti-quorum sensing activity of airborne microorganisms detected by a rapid method
Abstract INTRODUCTION: Introducing new antibiotics to the clinic is critical. METHODS: We adapted a plate method described by Kawaguchi and coworkers in 20131 for detecting inhibitory airborne microorganisms. RESULTS: We obtained 51 microbial colonies antagonist to Chromobacterium violaceum, purified and retested them, and of these, 39 (76.5%) were con

3. Isolados de Dicyma pulvinata em estromas de Microcyclus ulei em seringueira.
Dicyma pulvinata é um eficiente agente de biocontrole de Microcyclus ulei, causador do mal-das-folhas da seringueira. O objetivo deste trabalho foi obter isolados com grande potencial antagônico. Em levantamentos realizados em 14 municípios produtores de borracha, localizados nos Estados do Acre, Amazonas, Bahia, Mato Grosso, Pará e Rondônia, obtiveram-

4. Planejamento, síntese, biotransformação e avaliação farmacológica de novos candidatos a protótipos de fármacos antipsicóticos / Planning, synthesis, biotransformation and pharmacological evaluation of new candidate prototype antipsychotic drugs
In the scope of a research program that aim the design, synthesis and pharmacological evaluation of new lead-compounds, we will describe in this work the design of new N-phenylpiperazines derivatives originally designed from clozapine (27) and LASSBio 579 (40) that shows antagonist profile in dopaminergic receptors. The compound 1-(4-nitrophenyl)-4-((1-pheny

5. Diversidade da comunidade bacteriana endofítica de sementes de soja e o seu potencial biotecnológico / Endophytic bacterial community diversity of soybean seeds and its biotechnological potential
Plant tissues, including seeds, are inhabited by microorganisms called endophytes, whose interaction with the plant can offer advantages to the host. It is known that plants growth promotion is induced by indole acetic acid (IAA) synthesis, phosphate solubilization and nitrogen fixation, among others. The control of phytopathogenic fungi is also related to a

6. Efeito in vitro de Saccharomyces cerevisiae sobre Guignardia citricarpa, agente causal da pinta preta dos citros. / In vitro effect of Saccharomyces cerevisiae on Guignardia citricarpa, causal agent of citrus black spot.
Due to the consumers perception about the impact caused by pesticides utilization over the environment and human health, besides the acquisition of resistance for part of the phytopathogens, the society has exercised pressures that had led to the establishment of governmental politics that restrict the use of fungicides leading agriculturists and researchers

7. Molecular Characterization of the Plasma Membrane H+-ATPase, an Antifungal Target in Cryptococcus neoformans
The Cryptococcus neoformans PMA1 gene, encoding a plasma membrane H+-ATPase, was isolated from a genomic DNA library of serotype A strain ATCC 6352. An open reading frame of 3,380 nucleotides contains six introns and encodes a predicted protein consisting of 998 amino acids with a molecular mass of approximately 108 kDa. Plasma membranes were isolated, and t

8. Cloning of Genes Involved in the Synthesis of Pyrrolnitrin from Pseudomonas fluorescens and Role of Pyrrolnitrin Synthesis in Biological Control of Plant Disease
A soil isolate of Pseudomonas fluorescens (BL915) was shown to be an effective antagonist of Rhizoctonia solani-induced damping-off of cotton. Investigation of the biological basis of this antagonism revealed that the strain produces pyrrolnitrin, a secondary metabolite known to inhibit R. solani and other fungi. Mutants of strain BL915 that did not produce

9. Regulatory RNA as Mediator in GacA/RsmA-Dependent Global Control of Exoproduct Formation in Pseudomonas fluorescens CHA0
In Pseudomonas fluorescens CHA0, an antagonist of root-pathogenic fungi, the GacS/GacA two-component system tightly controls the expression of antifungal secondary metabolites and exoenzymes at a posttranscriptional level, involving the RNA-binding protein and global regulator of secondary metabolism RsmA. This protein was purified from P. fluorescens, and R
