Here we embark in a deep metagenomic survey that revealed the taxonomic and potential metabolic pathways aspects of mangrove sediment microbiology. The extraction DNA from samples direct application pyrosequencing resulted approximately 215 Mb data four distinct areas (BrMgv01 to 04) Brazil. approaches applied dominance Deltaproteobacteria Gammaproteobacteria samples. Paired statistical analysis showed higher proportions specific groups each dataset. reconstruction indicated possible...
We used the T-RFLP technique combined with Ion Torrent (PGM) sequencing of 16S rRNA and multivariate analysis to study structure bulk soil rhizosphere bacterial communities a cactus, Cereus jamacaru, from Brazilian Caatinga biome, which is unique Brazil. The availability water shapes communities, resulting in different patterns during rainy dry seasons. Taxonomic approaches statistical revealed that phylum Actinobacteria strongly correlated season, while samples season exhibited strong...
The processes of land conversion and agricultural intensification are a significant cause biodiversity loss, with consequent negative effects both on the environment sustainability food production.The anthrosols associated pre-Colombian settlements in Amazonian region examples how anthropogenic activities may sustain native populations against harsh tropical environments for human establishment, even without previous intentionality anthropic soil formation. In case study (Model...
Root-knot nematodes (Meloidogyne spp.) threaten global agricultural production. Bacteria that inhabit the nematode egg mass have not been well explored. Using a metataxonomic approach based on sequencing 16S rRNA gene of bacteria communities associated with Meloidogyne exigua masses, we found significant differences in bacterial composition and diversity masses symptomatic coffee plants compared to asymptomatic ones, for first time field conditions. The families Pseudomonadaceae,...
Bacterial communities associated with sponges are influenced by environmental factors; however, some degree of genetic influence the host on microbiome is also expected. In this work, 16S rRNA gene amplicon sequencing revealed diverse bacterial phylotypes based phylogenies three tropical (Aplysina fulva, Aiolochroia crassa and Chondrosia collectrix). Despite their sympatric occurrence, studied presented different compositions that differed from those observed in seawater. However, lower...
The study of the ecology soil microbial communities at relevant spatial scales is primordial in wide Amazon region due to current land use changes. In this study, diversity Archaea domain (community structure) and ammonia-oxidizing (richness community composition) were investigated using molecular biology-based techniques different land-use systems western Amazonia, Brazil. Soil samples collected two periods with high precipitation (March 2008 January 2009) from Inceptisols under primary...
The mangrove ecosystem is an unexplored source for biotechnological applications. In this unique environment, endemic bacteria have the ability to thrive in harsh environmental conditions (salinity and anaerobiosis), act degradation of organic matter, promoting nutrient cycles. Thus, study aimed assess cellulolytic activities bacterial groups present sediment from a located Ilha do Cardoso (SP, Brazil). To optimize isolation bacteria, enrichments two types culture media (tryptone broth...
Abstract Leaf decomposition is the primary process in release of nutrients dynamic mangrove habitat, supporting ecosystem food webs. On most environments, fungi are an essential part this process. However, due to peculiarities forests, group currently neglected. Thus, study tests hypothesis that fungal communities display a specific succession pattern different species and differences their ecological role. A molecular approach was employed investigate dynamics community during three common...
An analysis of the effect an oil spill on mangrove sediments was carried out by contamination mesocosms derived from two different mangroves, one with a history and pristine. The association between N(2) fixers hydrocarbon degradation assessed using quantitative PCR (qPCR) for genes rrs nifH, nifH clone library sequencing total petroleum (TPH) quantification gas chromatography. TPH showed that microbial communities both mangroves were able to degrade hydrocarbons added; however, whereas...
Summary Semiarid environments are characterized by the uneven spread of rain throughout year. This leads to establishment a biota that can go through long periods without rain. In order understand dynamics rhizosphere microbial communities across these contrasting seasons in C aatinga, we used I on T orrent platform sequence metagenome native leguminous plant ( M imosa tenuiflora ). The annotation indicated most abundant groups detected were Actinobacteria and Proteobacteria, dominant...
Mangrove forests encompass a group of trees species that inhabit the intertidal zones, where soil is characterized by high salinity and low availability oxygen. The phyllosphere these represent habitat provided on aboveground parts plants, supporting in global scale, large complex microbial community. structure communities reflects immigration, survival growth colonizers, which influenced numerous environmental factors addition to leaf physical chemical properties. Here, combination...
