1. Plant growth-promoting endophytic bacteria on maize and sorghum1
RESUMO Bactérias promotoras de crescimento em plantas (BPCP) são encontradas em tecidos vegetais e promovem o crescimento vegetal por meio da secreção de hormônios e enzimas, ou auxiliando a absorção de nutrientes. Avaliaram-se quarenta isolados de BPCP para determinar seus efeitos sobre o crescimento de milho e sorgo. Estes isolados foram também com

2. Sugarcane inoculated with endophytic diazotrophic bacteria: effects on yield, biological nitrogen fixation and industrial characteristics
Abstract: The growing need for the use of clean energy has led society to seek alternatives to fossil fuels in order to less pollute the environment. Sugarcane has been known to produce enough biomass and to have associative microorganisms, such as plant growth-promoting bacteria (PGPB), which have the potential to improve the yield of crops. The objective

3. Efficacy of vermicompost and/or plant growth promoting bacteria on the plant growth and development in gladiolus
Abstract The use of environmental and sustainable ornamental flower production practices with renewable resources has drawn worldwide interest. One of these renewable resources is vermicompost (earthworm castings). In recent years, increasing demand for improving environmental quality have focused on the importance of Plant Growth Promotion Bacteria (PGPBs)

4. Ammonium excretion, auxin production and effects of maize inoculation with ethylenediamine-resistant mutants of Pseudomonas sp.
ABSTRACT Plant growth-promoting bacteria (PGPB) comprise part of plant microbiome of biotechnological interest due to their potential to decrease the use of agrochemicals in agriculture. Among the commonly found PGPB species, the Pseudomonas genus is known for high competitiveness and efficiency in expressing growth-promotion traits. To increase the contribu

5. Plant growth-promoting bacteria as inoculants in agricultural soils
Abstract Plant-microbe interactions in the rhizosphere are the determinants of plant health, productivity and soil fertility. Plant growth-promoting bacteria (PGPB) are bacteria that can enhance plant growth and protect plants from disease and abiotic stresses through a wide variety of mechanisms; those that establish close associations with plants, such as

6. Cultivable endophytic bacteria from leaf bases of Agave tequilana and their role as plant growth promoters
Agave tequilana Weber var. 'Azul' is grown for the production of tequila, inulin and syrup. Diverse bacteria inhabit plant tissues and play a crucial role for plant health and growth. In this study culturable endophytic bacteria were extracted from leaf bases of 100 healthy Agave tequilana plants. In plant tissue bacteria occurred at mean population densitie

7. Caracterização de bactérias promotoras de crescimento vegetal em Vriesea gigantea Gaud. e Tillandsia aeranthos (Loiseleur) L.B. Smith (Bromeliaceae)
Microrganismos que habitam o interior e a superfície podem fornecer substancias essenciais ao crescimento das plantas, como fitormônios e nutrientes essenciais. O presente trabalho teve como objetivo isolar e caracterizar as bactérias da filosfera, do ambiente endofítico e a água de tanque associadas à Vriesea gigantea e Tillandsia aeranthos. As bacté

8. Diversidade morfolÃgica e genÃtica de rizobactÃrias endofÃticas obtidas de solos de diferentes classes e manejos de cultivo / Morphological and genetic diversity of endophytic rhizobacteria obtained from soil of different classes and crop managements
O nitrogÃnio à um dos fatores mais limitantes da produÃÃo vegetal, porÃm sua disponibilizaÃÃo contÃnua pela agricultura atravÃs da aplicaÃÃo de fertilizantes quÃmicos acarreta em altos custos financeiros, energÃticos e ambientais. Com intuito de reduzir estes custos, vÃrios estudos vÃm sendo realizados quanto à fixaÃÃo biolÃgica de nitrog�

9. Construção de sistemas bacterianos para a detecção de metais pesados em amostras ambientais. / Construction of bacterial systems for the detection of heavy metals in environmental samples.
Aiming at the construction of three bacterial biosensors for metals mercury, arsenic and lead, Cupriavidus metallidurans CH34 was chosen to obtain the DNA fragments (by PCR) corresponding to operons mer, ars and pbr. The fragments were inserted upstream of the EGFP gene, in plasmid pBB-EGFP, getting three new plasmids: pGHg, pGAs and pGPb. They were cloned i

10. Triple inoculation with Bradyrhizobium, Glomus and Paenibacillus on cowpea (Vigna unguiculata [L.] walp.) development
The use of microorganisms to improve the availability of nutrients to plants is of great importance to agriculture. This study aimed to evaluate the effect of triple inoculation of cowpea with arbuscular mycorrhizal fungi (AMF), plant growth-promoting bacteria (PGPB) and rhizobia to maximize biological nitrogen fixation (BNF) and promote plant growth. The ex

11. RizobactÃrias promotoras de crescimento e fungos micorrÃzicos arbusculares no desenvolvimento de mudas micropropagadas de bananeira
In order to study the effect of plant growth promoted bacteria (PGPB) and arbuscular mycorrhizal fungi (AMF) on development of micropropagated banana seedlings three experiments were performed. Endophytic and epiphytic bacteria were isolated from roots of six cultivars of banana and characterized regarding production of pectinase, celulase, indolacetic acid,

12. Membrane-bound phosphatases in Escherichia coli: sequence of the pgpB gene and dual subcellular localization of the pgpB product.
The phosphatidyl glycerophosphate B phosphatase of Escherichia coli has a multiple substrate specificity and a peculiar dual subcellular localization in the envelope. Its phosphatidyl glycerophosphate phosphatase activity is higher in the cytoplasmic membrane, while phosphatidic acid and lysophosphatidic acid phosphatase activities are higher in the outer me
