Interspecific variation of the bacterial community structure in the Phyllosphere of the three major plant components of mangrove forests. Repositório Alice
DIAS, A. C. F.; TAKETANI, R. G.; ANDREOTE, F. D.; LUVIZOTTO, D. M.; SILVA, J. L. da; NASCIMENTO, R. dos S.; MELO, I. S. de.
ABSTRACT: Mangrove forests encompass a group of trees species that inhabit the intertidal zones, where soil is characterized by the high salinity and low availability of oxygen. The phyllosphere of these trees represent the habitat provided on the aboveground parts of plants, supporting in a global scale, a large and complex microbial community. The structure of phyllosphere communities reflects immigration, survival and growth of microbial colonizers, which is influenced by numerous environmental factors in addition to leaf physical and chemical properties. Here, a combination of culture-base methods with PCR-DGGE was applied to test whether local or plant specific factors shape the bacterial community of the phyllosphere from three plant species...

Isolation and enzyme bioprospection of endophytic bacteria associated with plants of Brazilian mangrove ecosystem. Repositório Alice
CASTRO, R. A.; QUECINE, M. C.; LACAVA, P. T.; BATISTA, B. D.; LUVIZOTTO, D. M.; MARCON, J.; FERREIRA, A.; MELO, I. S. de; AZEVEDO, J. L..
Abstract: The mangrove ecosystem is a coastal tropical biome located in the transition zone between land and sea that is characterized by periodic flooding, which confers unique and specific environmental conditions on this biome. In these ecosystems, the vegetation is dominated by a particular group of plant species that provide a unique environment harboring diverse groups of microorganisms, including the endophytic microorganisms that are the focus of this study. Because of their intimate association with plants, endophytic microorganisms could be explored for biotechnologically significant products, such as enzymes, proteins, antibiotics and others. Here, we isolated endophytic microorganisms from two mangrove species, Rhizophora mangle and Avicennia...

The microbiome of brazilian mangrove sediments as revealed by metagenomics. Repositório Alice
ANDREOTE, F. D.; JIMENEZ, D. J.; CHAVES, D.; DIAS, A. C. F.; LUVIZOTTO, D. M.; DINI-ANDREOTE, F.; FASANELLA, C. C.; VARON LOPEZ, M.; BAENA, S.; TAKETANI, R. G.; MELO, I. S. de.
ABSTRACT: Here we embark in a deep metagenomic survey that revealed the taxonomic and potential metabolic pathways aspects of mangrove sediment microbiology. The extraction of DNA from sediment samples and the direct application of pyrosequencing resulted in approximately 215 Mb of data from four distinct mangrove areas (BrMgv01 to 04) in Brazil. The taxonomic approaches applied revealed the dominance of Deltaproteobacteria and Gammaproteobacteria in the samples. Paired statistical analysis showed higher proportions of specific taxonomic groups in each dataset. The metabolic reconstruction indicated the possible occurrence of processes modulated by the prevailing conditions found in mangrove sediments. In terms of carbon cycling, the sequences indicated...
