1. Evaluation of bacterial diversity recovered from petroleum samples using different physical matrices
ABSTRACT Unraveling the microbial diversity and its complexity in petroleum reservoir environments has been a challenge throughout the years. Despite the techniques developed in order to improve methodologies involving DNA extraction from crude oil, microbial enrichments using different culture conditions can be applied as a way to increase the recovery of D

2. Caracterização funcional de dois cDNAs homólogos à ciclofilina e à proteína reprimida por auxina (ARP) identificados em bibliotecas subtrativas a para floração em tomateiro
A floração é fundamental no ciclo de vida de uma planta. Este processo é marcado pela conversão do meristema apical vegetativo em reprodutivo, devido a interações entre diversos fatores, tanto internos quanto externos à planta. Diante disso, foram construídas oito bibliotecas subtrativa utilizando ápices meristemáticos induzidos e não induzidos p

3. Triagem, aplicação e engenharia de biocatalisadores para transformações enantio e regiosseletivas / Screening, applying and engineering biocatalysts for enantio and regioselective transformations
Biocatalysts have been widely applied in recent decades for industrial processes yielding high value products under environmentally friendly reaction conditions. The development of biocatalysts often begins with screening to identify enzymes with suitable activities followed by characterization of the enzymes chemo-, regio- and stereoselectivity or stability

4. Molecular identification of methanogenic archaea from Surti buffaloes (bubalus bubalis), reveals more hydrogenotrophic methanogens phylotypes
Methane emissions from ruminant livestock are considered to be one of the more potent forms of greenhouses gases contributing to global warming. Many strategies to reduce emissions are targeting the methanogens that inhabit the rumen, but such an approach can only be successful if it targets all the major groups of ruminant methanogens. Therefore, a thorough

5. Development and validation of SSR markers for Coffea arabica L.
With the objective of developing new SSR markers for Coffea arabica, two enriched genomic libraries with probes (GT)15 and (AGG)10 were constructed. A total of 835 clones were sequenced and 756 presented good quality sequences. Redundant sequences were observed for 113 clones (14.94%). SSRs were found in 287 clones (38%). An estimated size of 417.5Kb of the

7. Differential gene expression, induced by salicylic acid and Fusarium oxysporum f. sp. lycopersici infection, in tomato.
The objective of this work was to determine the transcript profile of tomato plants (Lycopersicon esculentum Mill.), during Fusarium oxysporum f. sp. lycopersici infection and after foliar application of salicylic acid. The suppression subtractive hybridization (SSH) technique was used to generate a cDNA library enriched for transcripts differentially expr

8. Bioprospecção de genes envolvidos na síntese de biossurfactantes a apartir de microbiota de resevatórios de petróleo / Bioprospection of genes involved in the synthesis of biosurfactants from braziliam petroleum reservoirs microbial communities
Bioemulsifiers or biosurfactants are compounds produced by microorganisms which enhance the bioavailability of hydrophobic substances promoting the stabilization of substances with different polarities, like oil-in-water emulsion occurring in petroleum reservoirs. The samples used in this work were collected in the Potiguar Basin (RN, Brazil), and employed a

9. Caracterização de comunidades microbianas relacionadas ao metabolismo de hidrocarbonetos leves presentes em amostras de solo. / Characterization of microbial communities involved in short-chain alkane metabolism in soil samples.
Solos apresentam hidrocarbonetos gasosos em quantidades variáveis e acredita-se que as formações de reservatórios de óleo podem ser detectáveis indiretamente utilizando-se bactérias no solo capazes de degradá-los. O presente estudo teve como objetivo caracterizar comunidades microbianas envolvidas com o metabolismo desses hidrocarbonetos. As amostras

10. Bacterial diversity of the 16S rRNA gene in pyrogenic black carbon of Anthropogenic Dark Earth from the Central and Oriental Amazon / Diversidade bacteriana do gene 16S rRNA em carvão pirogênico de Terra Preta Antropogênica da Amazônia Central e Oriental
Anthropogenic Dark Earth (ADE) has this denomination because it is found at archeological sites, where prehistoric groups lived, and it is considered one of the most fertile soils of the world. In this soil a great amount of material left by indigenous groups was found as ceramic fragments, lithic workmanships, and especially pyrogenic black carbon. Studies

11. Prospecção de genes de interesse biotecnológico : uma abordagem metagenômica
The total number of prokaryotic cells on Earth has been estimated at 4 to 6x1030 and only about 1% of microorganisms present in the environment can be cultivated by standard techniques of cultivation and plating. Therefore, it is a huge biological and genetic pool that can be exploited, for the identification and characterization of genes with biotechnologic

12. Diversidade de bactérias em amostras de água do mar no canal de São Sebastião / Diversity of bacteria in seawater samples at São Sebastião Channel
A diversidade bacteriana pode ser estudada, combinando técnicas convencionais e técnicas que empreguem tecnologias modernas para sua melhor compreensão. O objetivo do trabalho foi analisar a diversidade de bactérias cultiváveis e não cultiváveis em amostras de água do mar coletadas no Canal de São Sebastião no período de agosto/2005 a março/2007.
