1. Role of Rhizobia in Suppressing the Root Diseases of Soybean Under Soil Amendment
RESUMO: Os rizóbios são bactérias que vivem no solo, caracterizadas pela capacidade única de colonizar as raízes das culturas de leguminosas, onde formam nódulos de fixação de nitrogênio. Foram acumuladas diversas evidências com o objetivo de identificar os benefícios associados ao uso de rizóbios como agentes de controle biológico contra patóg

2. Nitrogen-fixing bacteria and arbuscular mycorrhizal fungi in Piptadenia gonoacantha (Mart.) Macbr.
Abstract The family Leguminosae comprises approximately 20,000 species that mostly form symbioses with arbuscular mycorrhizal fungi (AMF) and nitrogen-fixing bacteria (NFB). This study is aimed at investigating and confirming the dependence on nodulation and biological nitrogen fixation in the specie Piptadenia gonoacantha (Mart.) Macbr., which belongs to th

3. Symbiotic effectiveness of Bradyrhizobium ingae in promoting growth of Inga edulis Mart. seedlings
ABSTRACT Inga edulis Mart. is a leguminous tree adapted to acidic and low-fertility soils that establishes symbioses with nitrogen (N)-fixing bacteria. The identification of effective bacteria in biological N fixation may bolster the use of I. edulis in degraded or modified areas and agroforestry systems. Therefore, the aims of this study were evaluation of

4. Bacterial strains from floodplain soils perform different plant-growth promoting processes and enhance cowpea growth
ABSTRACT Certain nodulating nitrogen-fixing bacteria in legumes and other nodule endophytes perform different plant-growth promoting processes. The objective of this study was to evaluate 26 bacterial strains isolated from cowpea nodules grown in floodplain soils in the Brazilian savannas, regarding performance of plant-growth promoting processes and ability

5. Diversidade de bactérias diazotróficas e fixação biológica do nitrogênio na Mata Atlântica / Diversity of diazotrophic bacteria and biological nitrogen fixation in Brazilian Atlantic Rainforest
O presente trabalho estudou as relações entre as taxas de fixação biológica de nitrogênio (FBN), a composição e a diversidade da comunidade de bactérias diazotróficas de vida livre em três compartimentos: solo sob a copa, filosfera e dermosfera de diferentes espécies arbóreas, sendo que dermosfera foi avaliada em apenas duas espécies. As planta

6. Diversidade e potencial biotecnológico de Pseudomonas spp. de sedimentos de manguezais. / Diversity and biotechnological potential of Pseudomonas spp. from mangrove sediments.
Os manguezais estão localizados na interface entre o continente e o oceano em regiões intertropicais, possuindo condições ambientais únicas. O objetivo deste trabalho foi avaliar a diversidade e o potencial biotecnológico da comunidade de Pseudomonas spp. em sedimentos de manguezais com diferentes estágios de preservação, no Estado de São Paulo. A

7. Multilocus sequence analysis (MLSA) of Bradyrhizobium strains: revealing high diversity of tropical diazotrophic symbiotic bacteria
Symbiotic association of several genera of bacteria collectively called as rhizobia and plants belonging to the family Leguminosae (=Fabaceae) results in the process of biological nitrogen fixation, playing a key role in global N cycling, and also bringing relevant contributions to the agriculture. Bradyrhizobium is considered as the ancestral of all nitroge

8. Solubilização de fosfato por fungos do solo e eficiência de sua inoculação em caupi e milho / Phosphate solubilization by soil fungi and their efficiency in corn and cowpea inoculation
The process of biological nitrogen fixation in leguminous is achieved by bacteria forming nodules possessing the nitrogenase enzyme that are able to catalyze the reduction of molecular nitrogen to ammonia which is assimilated by the plants. Despite the high diversity of the Kingdom Fungi, reports on the solubilization on phosphates by fungi have been restric

9. Reserva nitrogenada no genero Beijerinckia isolada da rizosfera de cana-de-açúcar. / Nitrogen reserve in the genus Beijerinckia isolated from sugarcane rhizosphere.
Beijerinckia sp. bacteria free-living nitrogen-fixing, commonly found in tropical lateritic soils. The cyanophycin produced by cyanobacteria is the only intracellular nitrogen reserve described to date. This study aimed to verify the intracellular buildup of nitrogen associated with Biological Nitrogen Fixation in five Beijerinckia isolated from the rhizosph

10. Density and diversity of diazotrophic bacteria isolated from Amazonian soils using N-free semi-solid media
Non-symbiotic diazotrophic bacteria are amongst the most important functional groups of soil-dwelling microorganisms. These bacteria contribute to plant growth predominantly through biological N2 fixation. Here, we evaluated the density and diversity of non-symbiotic diazotrophic bacteria in soils taken from diverse land use systems (LUS) in Amazonia using n

11. The nematicidal effect of some bacterial biofertilizers on Meloidogyne incognita in sandy soil
In a greenhouse experiment, the nematicidal effect of some bacterial biofertilizers including the nitrogen fixing bacteria (NFB) Paenibacillus polymyxa (four strains), the phosphate solubilizing bacteria (PSB) Bacillus megaterium (three strains) and the potassium solubilizing bacteria (KSB) B. circulans (three strains) were evaluated individually on tomato p

12. Mapping QTLs for traits associated with biological nitrogen fixation (BNF) in soybeans / Mapeamento de QTLs para caracteres relacionados com a fixação biológica de nitrogênio (FBN) em soja
Soybeans [Glycine max (L.) Merrill] is a crop with high protein content (about 40%) in the seeds. As a result, the crop demands high nitrogen (N) inputs, which can be supplied by the process of biological nitrogen fixation (BNF), through the symbiosis with bacteria of the genus Bradyrhizobium. In Brazil the BNF allows to fulfill all the demand for N; therefo
