1. OPTIMIZATION OF THE OPERATING CONDITIONS FOR RHAMNOLIPID PRODUCTION USING SLAUGHTERHOUSE-GENERATED INDUSTRIAL FLOAT AS SUBSTRATE
AbstractBiosurfactants have a wide range of applications in emulsions, separations, and solubilization because these chemicals reduce the surface tension and viscosity of solutions. This work studied rhamnolipid production using a batch bioreactor with a working volume of 1.5 liters, Pseudomonas aeruginosa ATCC (American Type Culture Collection) 10145 strain

2. Identificação de genes diferencialmente expressos em feijoeiro envolvidos na resistência ao estresse hídrico / Identification of differentially expressed genes in common bean involved in drought stress resistance
O Brasil é o segundo maior produtor de feijão, sendo a espécie mais cultivada o Phaseolus vulgaris L. Entre as três possíveis safras exploradas no Brasil, aquela que gera a maior produção é a da seca. Por outro lado, como a maioria das lavouras emprega pouca tecnologia, um dos problemas desta cultura é o estresse hídrico, que leva a uma redução n

3. Aproveitamento de efluente gorduroso gerado por abatedouro e frigorífico para produção de biossurfactante
Os surfactantes produzidos por micro-organismos apresentam as mesmas características dos surfactantes sintéticos, sendo capazes de reduzir a tensão superficial em soluções aquosas e em misturas de hidrocarbonetos Neste trabalho estudou-se a produção de biossurfactante por fermentação de gorduras provenientes de flotadores de estação de tratamento

4. Produção e composição dos polissacarídeos extracelulares de Planktothrix agardhii (Cyanobacteria) e suas relações com bactérias no reservatório de Barra Bonita
The organism Planktothrix agardhii belongs to one of the two most abundant genera in the world among the phytoplankton (the other is Microcystis sp.). Nevertheless, the genus Planktothrix is potentially toxic, producing microcystins and anotoxinas, which makes relevant knowledge of the biology of species that produce large biomass, as the case of P. agardhii

5. Caracterização dos componentes extracelulares produzidos em cultura de célula de Rubus fruticosus (amora-preta) durante resposta de hipersensibilidade / Characterization of the extracellular compounds released from Rubus fruticosus (blackberry) cell during a hypersensitive response.
The plant-pathogen interactions trigger a series of signals that are not yet completely understood. One of the mechanisms is the hypersensitive response (HR), which is characterized by cell death in the infection site in order to prevent pathogen proliferation. Our previous studies with different elicitors demonstrated the correlation between the formation o

6. Otimização da Produção e Caracterização de Goma Xantana Empregando Caldo de Cana
Xanthan gum production and its structural characterization under the conditions optimized by experimental design were the main objectives of this study. Several reports point to the sugar cane broth as an excellent raw material for the production of fermentable media, under the microbial species different action (bacteria, yeasts, fungi) in the products bios

7. Caracterização funcional de uma xiloglucano galactosiltransferase de Eucalyptus grandis e uma ramnose sintase de Arabidopsis thaliana: Efeitos sobre a estrutura e composição da parede celular primária / Functional characterization of a xyloglucan galactosyltransferase of Eucalyptus grandis and a rhamnose synthase of Arabidopsis thaliana: Effects upon the structure and composition of the primary cell wall
The plant cell wall has been associated with several important biological functions. It surrounds the plant, protecting it against mechanical injuries, biotic and abiotic stresses. In addition, plant cell walls determine cell shape and growth rates. The main constituents of plant cell walls are: cellulose, hemicellulose, pectine, lignin and proteins, which v

8. Produção de biossurfactante por Pseudomonas Aeruginosa empregando óleo de soja residual
This work has as objective to investigate the production of biosurfactant employing strain of Pseudomonas aeruginosa using as source of carbon residual soybean oil from several foods frying. In the first assay the Pseudomonas aeruginosa were used ATCC 9027, isolated Pseudomonas aeruginosa from Landfarming REDUC (PALR) and a Pseudomonas aeruginosa PACL strain

9. Alteration in the composition of cell wall polysaccharides in Nicotina tabacum by modulating the expression of the uxs gene, coding for UDP-D-glucuronic acid decarboxylase enzyme (EC 4.1.1.35) / Alteração da composição dos polissacarídeos da parede celular de Nicotiana tabacum, pela modulação da expressão do gene uxs que codifica a enzima UDP-D-glucuronato descarboxilase (EC 4.1.1.35)
The plant cell wall is not only an essential structure for plants, but also an extremely important raw material in human economy. The plant cell wall has diverse utilities, for example, papermaking, textile fiber, civil construction. Polysaccharides, such as cellulose, hemicelluloses and pectins, are the major components of the primary plant cell wall (appro

10. PurificaÃÃo e caracterizaÃÃo de antibacterianos de plantas do municÃpio de Lavras, MG. / Purification and identification of antibacterials from Lavras city plants.
Screening of 30 methanol extracts from plants collected in Lavras city (MG) was conducted using the agar diffusion method to identify antibacterial properties against Aeromonas hydrophila ATCC 7966, Bacillus subtilis ATCC 6633, Pseudomonas aeruginosa ATCC 27853 and Staphylococcus aureus ATCC 25923. It was observed that 13 of them presented antibacterial acti

Forty eigth Shiga toxin-producing Escherichia coli (STEC) strains, the majority from human origin, and thirty non-STEC strains carrying eae and belonging to the same serogroups of STEC strains, and isolated between 1976 and 2003 were studied. Phenotypical traits, virulence characteristics and genetic diversity were evaluated. The majority of STEC strains was
