Metabolism of various carbon sources by Azospirillum brasilense [PDF]
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 ...

Mutation in a D-alanine-D-alanine ligase of Azospirillum brasilense Cd results in an overproduction of exopolysaccharides and a decreased tolerance to saline stress [PDF]
Bacteria of the genus Azospirillum are free-living nitrogen-fixing, rhizobacteria that are found in close association with plant roots, where they exert beneficial effects on plant growth and yield in many crops of agronomic importance.

Does soil cultivation practices and inoculation with Azospirillum brasilense affect the performance of maize genotypes? [PDF]
One of the bottlenecks for maize (Zea mays L.) production is the need for a large supply of nitrogen fertilizers, which burdens farmers. A solution to this problem is the use of proteobacteria Azospirillum brasilense as an inoculant.

Temperature inhibition of siderophore production in Azospirillum brasilense [PDF]
The effect of growth at 42 degrees C on the different components of the siderophore-mediated iron transport that are induced by iron limitation in Azospirillum brasilense was examined. Biosynthesis of the siderophore spirilobactin was strongly inhibited (20-fold) by growth at 42 degrees C, whereas the transport of iron by the ferric-spirilobactin ...
