1. Impact of phosphate solubilizing bacteria on wheat (Triticum aestivum ) in the presence of pesticides
Resumo Três bactérias solubilizantes de fosfato foram isoladas e identificadas por seqüenciamento de rRNA 16S como Pseudomonas putida, Pseudomonas sp e Pseudomonas fulva. As estirpes foram submetidas a testes bioquímicos de plantas e todos os atributos PGPR foram verificados na presença de pesticidas (clorpirifos e piriproxifeno). O índice de solubili

2. Dissolving mechanism of strain P17 on insoluble phosphorus of yellow-brown soil
Strain P17 was a bacterial strain identified as Bacillus megaterium isolated from ground accumulating phosphate rock powder. The fermentation broth of strain P17 and the yellow-brown soil from Nanjing Agricultural University garden were collected to conduct this study. The simulation of fixed insoluble phosphorous forms after applying calcium superphosphate

3. 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

4. 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

5. Indicadores biológicos associados ao ciclo do fósforo em solos de cerrado utilizando plantio direto e plantio convencional.
RESUMO: O objetivo deste trabalho foi avaliar a influência do plantio direto, do preparo convencional do solo e de plantas de cobertura sobre indicadores biológicos associados ao ciclo do fósforo (P). O trabalho foi realizado em três áreas adjacentes, num Latossolo Vermelho-Amarelo, distribuídas da seguinte maneira: área I, dois anos de experimentaç�

6. Isolamento e caracterização de bactérias diazotróficas em arroz silvestre (Oriza glumaepatula Steud) no Estado de Roraima
Species of wild rice are colonized by diazotrophic bacterias, however, little is known about the colonization in Oryza glumaepatula (Steud). This study aimed isolate and characterize diazotrophic bacterias of the wild rice from forest and cerrado areas in the Amazon biome. Samples of wild plants were collected for bacterial isolation, and semi-solid medium w

7. Solubilization of phosphorus by endofhytic bacteria / Solubilização de fósforo por bactérias endofíticas
Soil microorganisms directly affect fertility and plant yield. Among these, inorganic phosphate solubilizers enhance phosphorus availability, and may increase phosphorus fertilizers efficiency. This work aimed to select inorganic phosphorus solubilizing bacteria as potential plant growth promoters. On the first stage, previously obtained isolates, from leave

8. FixaÃÃo biolÃgica de nitrogÃnio e solubilizaÃÃo de fosfatos por bactÃrias isoladas de nÃdulos de caupi [Vigna unguiculata (L.) Walp.] / Biological nitrogen fixation and phosphate solubilization by bacteria isolated from cowpea nodules [Vigna unguiculata (L.) Walp.]
The biological nitrogen fixation and solubilization of insoluble inorganic phosphates are processes mediated by soil microorganisms which can increase crop productivity. The objective of this study was to isolate and select bacteria nodulating cowpea and efficient in biological nitrogen fixation and solubilization of insoluble phosphates and, to identify and

9. Root colonization of maize and lettuce by bioluminescent Rhizobium leguminosarum biovar phaseoli.
Two strains of Rhizobium leguminosarum bv. phaseoli and three other plant growth-promoting rhizobacteria (PGPR) were examined for the potential of maize and lettuce root colonization. All of these strains were selected in vitro for their phosphate-solubilizing abilities. Maize and lettuce seeds were treated with derivatives of all strains marked with lux gen

10. Cloning of a mineral phosphate-solubilizing gene from Pseudomonas cepacia.
We have recently shown that the ability of some gram-negative bacteria to dissolve poorly soluble calcium phosphates (Mps+ phenotype) is the result of periplasmic oxidation of glucose to gluconic acid via the quinoprotein glucose dehydrogenase (GDH), a component of the direct oxidation pathway. Escherichia coli K-12 derivatives synthesize apo-GDH but not the
