1. Media preferences, micro-morphometric analysis, and cardinal growth temperature determination for Phytophthora infestans sensu lato isolated from different hosts in Colombia
Resumo Durante os últimos anos Phytophthora infestans sensu lato causou epidemias na Colômbia em lavouras de frutos andinos, como Solanum quitoense e Solanum betaceum. Estabelecimento de procedimentos experimentais novos ou modificados para estudar este patógeno é um assunto obrigatório para os cientistas. Doze isolados de Phytophthora spp. obtidos de

2. Cultura de anteras e partenogênese in situ e in vitro de genótipos de laranja doce (Citrus sinensis Osbeck.) / Anther culture and in vitro and in situ parthenogenesis of sweet orange (Citrus sinensis Osbeck.) genotypes
The production of completely homozygous lines in citrus breeding program is hard, and double-haploid plantlets (completely homozygous lines) can be used to improve these breeding programs. However, many factors are associated with the success of the regeneration of haploid or double-haploid plants. The aim of this study was the induction and regeneration of

3. Produção, otimização e caracterização bioquímica de fitase produzida por Burkholderia sp / Production, optimization and biochemical characterization of phytase produced by Burkholderia sp
O ácido fítico é a principal fonte de armazenamento de fósforo em cereais e legumes, sendo que sua forma sal é denominada fitato. O fitato não é digerido pelo trato gastrointestinal de animais monogástricos e, na alimentação humana, o fitato é considerado um fator antinutricional devido à sua capacidade quelante para vários metais e por ligar-se

4. Natural products from endophytic fungi found in association with Asteraceae species and antibiotic assay in the "Caenorhabditis elegans" infection model / Produtos naturais de fungos endofíticos associados a espécies de Asteraceae e ensaio antibiótico no modelo de infecção em "Caenorhabditis elegans"
The search for small bioactive molecules from under-explored natural sources that possess specific ecological interaction in their respective habitat has been emphasized as strategic for the discovery of bioactive compounds. Endophytic microorganisms are still relatively under-explored sources of natural products. These microorganisms live inside the host pl

5. Obtenção e caracterização filogenética de consórcio de bactérias púrpuras não-sulforosas consumidoras de ácidos orgânicos visando a produção de hidrogênio em reator anaeróbio de batelada / Obtaintion and phylogenetic characterization of consortium of phototrophic purple non-sulfur bacteria for hydrogen production from organic acids in the anaerobic batch reactor
The aim of this work was enrich a mixture of granular sludge of an up flow anaerobic sludge blanket (UASB) under anoxygenic phototrophic conditions. The techniques of molecular biology identified 17 operational taxonomic units (UTO) in the microbial consortium among the sequences analised, which were similar to Rhodobacter, genus widely cited in studies of h

6. Sobre o azul do mar: virtualidades reais e realidades virtuais / About the blue of the sea: real virtualities and virtual realities
The objective of this thesis is to discuss vision as a sociohistoric meaning-making process. Thus, contrary to the traditional approach to vision, which deals with it as a transparent and non-interpretative object, we look at it as a social practice through which we make sense of and in the world using our senses and body. For this discussion we counterpose

7. Processos de comunicação na mídia política: os comportamentos comunicacionais no cenário das campanhas eleitorais veiculadas no sistema televisivo reconciliação com a natureza -
This thesis is dedicated to investigate the source of electoral behavior, one being rational, logical and ideological and the other manifested mainly in the television, toward the seduction of the voter rather than his honest belief. To explain how such behavior, which sometimes seem to escape of what we call rationality, this research argues that elections

8. Biotyping of industrial yeasts by the Killer system. / Biotipagem de leveduras industriais através do sistema Killer.
Agriculture is an important sector in the economy of Brazil. The sugar cane occupies 9% of the cultivated area in this country. The most important products from the sugar cane industry are sugar and alcohol, the latest produced by fermentative process by yeasts. During the fermentation the yeast population changes due to the interferences coming from the sug

9. Do corpo-mÃquina ao corpo-informaÃÃo: o pÃs-humano como horizonte biotecnolÃgico
This research analyses the ways of problematization of the relations between body and new technologies put into practice by the media and academic field discoursive production. It is about thinking how the relation body and technology has become an issue, which discoursive practices, related with a variety of coexistent and lateral practices, has made this i

10. Caracterização anatômica da organogênese in vitro e transformação genética via Agrobacterium tumefaciens em Citrus sp. / Anatomical analysis of in vitro organogenesis and Agrobacterium tumefaciens-mediated transformation in Citrus sp.
Genetic transformation has been more frequently associated with conventional genetic breeding programs of different species. It allows for the introduction of exogenous gene(s) into the plant genome, with the possibility of altering specific characteristics. Thus, it can be an important tool for Citrus conventional breeding programs, which present several li

11. Cervical lymphadenitis caused by a fastidious mycobacterium closely related to Mycobacterium genavense in an apparently immunocompetent woman: diagnosis by culture-free microbiological methods.
Fastidious mycobacteria usually infect immunocompromised hosts (human immunodeficiency virus-infected or otherwise immunosuppressed patients). We here describe severe lymphadenitis, caused by a fastidious mycobacterium closely related to Mycobacterium genavense, in an apparently immunocompetent woman, whose brother had died from an unidentified mycobacterial

12. Cultivation of Pathogenic and Opportunistic Free-Living Amebas
Free-living amebas are widely distributed in soil and water, particularly members of the genera Acanthamoeba and Naegleria. Since the early 1960s, they have been recognized as opportunistic human pathogens, capable of causing infections of the central nervous system (CNS) in both immunocompetent and immunocompromised hosts. Naegleria is the causal agent of a
