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...
Brazil's large land base is important for global food security but its high dependency on inorganic phosphorus (P) fertilizer crop production (2.2 Tg rising up to 4.6 in 2050) not a sustainable use of critical and price-volatile resource. A new strategic analysis current future P demand/supply concluded that the nation's secondary resources which are produced annually (e.g. livestock manures, sugarcane processing residues) could potentially provide 20% demand by 2050 with further investment...
A plethora of microbial cells is present in every gram soil, and microbes are found extensively plant animal tissues. The mechanisms governed by microorganisms the regulation physiological processes their hosts have been studied light recent findings on microbiomes. In plants, components these microbiomes may form distinct communities, such as those inhabiting rhizosphere, endosphere phyllosphere. each niches, "microbial tissue" established by, responds to, specific selective pressures....
The world demand for phosphate has gradually increased over the last decades, currently achieving alarming levels considering available rock reserves. use of soil microorganisms, such as arbuscular mycorrhizal fungi (AMF), been suggested a promising alternative to improve phosphorus-use efficiency. However, effect source phosphorus on interactions within microbial community remains unclear. Here, we evaluated links between total dry matter content sugarcane and under different sources,...
In this study, the effects of plant genotype, soil type and nutrient use efficiency on composition different bacterial communities associated with rice roots were investigated. Thus, total bacteria, Alpha- Betaproteobacteria, Pseudomonas Actinobacteria studied using PCR, followed by denaturing gradient gel electrophoresis (PCR-DGGE). Rice genotype determined, to a large extent, across cultivars. Several cultivars belonging Oryza sativa ssp. indica tended select similar communities, whereas...
Sewage sludges generation and their disposal have become one of the greatest challenges 21st century. They great microbial diversity that may impact wastewater treatment plant (WWTP) efficiency soil quality whether used as fertilizers. Therefore, this research aimed to characterize community structure 19 sewage from São Paulo, Brazil, well draw relations sludge sources [domestic mixed (domestic+industrial)], biological treatments (redox conditions liming), chemical attributes, using...
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...
Mangrove soils are anaerobic environments rich in sulphate and organic matter. Although the sulphur cycle is one of major actors this ecosystem, little known regarding bacteria communities mangrove soils. We investigated abundance, composition diversity sulphur-oxidizing (SOB) sulphate-reducing (SRB) sediments from three Brazilian communities: two contaminated, with oil (OilMgv) urban waste sludge (AntMgv), pristine (PrsMgv). The community structures were assessed using quantitative...
Beneficial bacteria interact with plants by colonizing the rhizosphere and roots followed further spread through inner tissues, resulting in endophytic colonization. The major factors contributing to these interactions are not always well understood for most bacterial plant species. It is believed that specific functions required colonization, but also from side features needed, such as genotype (cultivar) developmental stage. Via multivariate analysis we present a quantification of roles...
Plant-bacteria interactions result from reciprocal recognition between both species. These are responsible for essential biological processes in plant development and health status. Here, we present a review of the methodologies applied to investigate shifts bacterial communities associated with plants. A description techniques is made initial isolations culture-independent approaches focusing on quantitative Polymerase Chain Reaction real time (qPCR), Denaturing Gradient Gel Electrophoresis...
Pseudomonas putida strain P9 is a novel competent endophyte from potato. causes cultivar-dependent suppression of Phytophthora infestans. Colonization the rhizoplane and endosphere potato plants by its rifampin-resistant derivative P9R was studied. The purposes this work were to follow fate inside growing establish effect on associated microbial communities. effects inoculation studied in two separate experiments. roots transplants three different cultivars dipped suspensions or cells,...
A taxonomic and annotated functional description of microbial life was deduced from 53 Mb metagenomic sequence retrieved a planktonic fraction the Neotropical high Andean (3,973 meters above sea level) acidic hot spring El Coquito (EC). classification unassembled reads using different databases showed proportion Gammaproteobacteria Alphaproteobacteria (in total read affiliation), through affiliation 16S rRNA gene fragments we observed presence Proteobacteria, micro-algae chloroplast...
