چکیده

Objetivou-se avaliar o efeito do Azospirillum brasilense associado à adubação nitrogenada na produção e qualidade da Brachiaria decumbens. O experimento foi conduzido em arranjo fatorial 2x4, com quatro repetições. Os tratamentos consistiram de dois fatores: sem inoculação A. doses N (0, 40, 80, 120 kg/ha). As características avaliadas foram: índice área foliar (IAF), interceptação luminosa (IL), densidade populacional perfilhos (DPP), SPAD, razão folha/colmo, matéria natural (MN), seca (MS) análises químico-bromatológicas. Constatou-se maiores resultados IL IAF, respectivamente, 62,2 74,4 kg/ha N. A proporcionou maior DPP até 80 N; acréscimos 11, 15 18,2% respectivamente nas aumento MN MS. Houve linear nos teores proteína bruta as elevou os carboidratos totais 40 contribui forma positiva desenvolvimento, decumbens quando dose nitrogênio.

Intermediary carbon metabolism of Azospirillum brasilense.

Azospirillum brasilense Sp 7 grew rapidly in AZO medium containing reduced nitrogen and succinate as an energy source, with a doubling time of 43 min. No growth was measured with glucose as the sole carbon source. In contrast, Azospirillum lipoferum Sp 59b could grow in media containing either succinate or glucose with a doubling time of 69 min and 223 min, respectively. Warburg-Barcroft respir...

Repressor mutant forms of the Azospirillum brasilense NtrC protein.

The Azospirillum brasilense mutant strains FP8 and FP9, after treatment with nitrosoguanidine, showed a null Nif phenotype and were unable to use nitrate as their sole nitrogen source. Sequencing of the ntrC genes revealed single nucleotide mutations in the NtrC nucleotide-binding site. The phenotypes of these strains are discussed in relation to their genotypes.

Extended phenotype of an mreB-like mutant in Azospirillum brasilense.

Tn5 mutagenesis was used to generate an Azospirillum brasilense SPF94 mutant. Genetic analysis of this mutant revealed that a homologue of the mreB gene, which controls cell shape in Bacillus subtilis and Escherichia coli, was inactivated. The cell-surface properties of the mutant were different from those of the parental strain. The mutant colonies were highly fluorescent when grown on plates ...

Temperature inhibition of siderophore production in Azospirillum brasilense.

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 transport system and the induction of the iron-r...
