Metabolism of various carbon sources by Azospirillum brasilense [PDF]

Journal of Bacteriology, 1983
Azospirillum brasilense Sp7 and two mutants were examined for 19 carbon metabolism enzymes. The results indicate that this nitrogen fixer uses the Entner-Doudoroff pathway for gluconate dissimilation, lacks a catabolic but has an anabolic Embden-Meyerhof-Parnas hexosephosphate pathway, has amphibolic triosephosphate enzymes, lacks a hexose ...

Morphometry and production of maize inoculated with Azospirillum brasilense

COLLOQUIUM AGRARIAE, 2021
This study aimed to analyze the influence of inoculation methods with Azospirillum brasilense in morphometric and nutritional parameters of the maize crop. Maize plants, hybrid Formula VT®, were grown under different forms of inoculation: absence of inoculation; seed inoculation; leaf inoculation; seed inoculation associated to leaf inoculation. In the

Calcofluor- and lectin-binding exocellular polysaccharides of Azospirillum brasilense and Azospirillum lipoferum [PDF]

Journal of Bacteriology, 1989
Extracellular polysaccharides synthesized by Azospirillum brasilense and A. lipoferum were shown on agar plates and liquid flocculating cultures. The six strains used in this work expressed a mucoid phenotype, yielding positive calcofluor fluorescence under UV light.

Modeling aerotaxis band formation in Azospirillum brasilense [PDF]

BMC Microbiology, 2019
Bacterial chemotaxis, the ability of motile bacteria to navigate gradients of chemicals, plays key roles in the establishment of various plant-microbe associations, including those that benefit plant growth and crop productivity. The motile soil bacterium Azospirillum brasilense colonizes the rhizosphere and promotes the growth of diverse plants across

Interaction of Azospirillum lipoferum with wheat germ agglutinin stimulates nitrogen fixation [PDF]

, 1999
In vitro, the nitrogen fixation capability of A. lipoferum is efficiently increased in the presence of wheat germ agglutinin (WGA). A putative WGA-binding receptor, a 32-kDa protein, was detected in the cell capsule.
