Agriculture microbiology and microbe interaction with plants. Azospirillum is an associative rhizobacteria which can be very useful for plants such as wheat.

Peningkatan penggunaan lipase untuk industri mendorong dilakukan penelitian untuk mendapatkan sumber-sumber lipase baru.

One of these options is the use of bio-fertilizers, for which the nitrogen fixing bacteria Azospirillum sp. When the same procedure was applied to A. The use of Azospirillum and N fertilizer combination affected the growth and rice yields, also reduced chemical fertilizer application.

Dual-purpose grain sorghum intercropped with palisade grass is a viable agronomic system for producing plant matter for silage during the autumn season.

At least five rhizobial species nodulate Phaseolus vulgaris in a spanish soil. In this work, we labeled Azospirillum brasilense FP2 wild type and HM excretion-ammonium strains by insertion of the reporter gene gusA-kanamycin into the dinitrogenase reductase coding gene, nifH, and evaluated bacteria aislamienro in barley Hordeum vulgare.


These results have biotechnological applicability and are dee great importance when defining and controlling the mass production conditions of Azospirillum spp.

This paper was cited 1 times until Mascarua-Esparza, M. El objetivo del presente trabajo fue evaluar el efecto de Rhizophagus intraradi – ces y Azospirillum brasilense sobre el crecimiento de C.

This study aimed to evaluate the effect of N doses-in the absence and presence of Azospirillum brasilense-on plant nutritional status at different growth stages and on seed yield of corn. Maize colonization by Acetobacter diazotrophicus. Genome structure of the genus Azospirillum. This suggests that AmtB has a role in scavenging ammonium at low concentrations.

Transcriptional regulation and signal-peptide-dependent secretion of exolevanase lsdb in the endophyte Gluconacetobacter Diazotrophicus. Several other volatiles having biological functions in other organisms, as well as numerous volatile compounds with undefined biological roles, were detected.

Azospirillum strains are known for their production of plant growth hormones that enhance root systems and for their ability to fix nitrogen. This gene is absent from the ANC-core despite its initial assignment as ancestral [ 12 ]; this discrepancy comes aislamiebto the fact that an orthologue is present in the genome of Magnetospirillum magneticum but absent from the genome of R.

To examine Arabidopsis development and reproductive success as affected by the bacteria, ABA and drought, a pot experiment using Arabidopsis Col-0 plants was also carried out. Per cent Pdff was higher with all levels of N over control, whereas, it was at par with their successive levels.

This suggests that these species produce IAA by other pathways. ajslamiento


We attempted to study the compatibility among plant beneficial bacteria in the culture level by growing them near in the nutrient agar plates. B [ 10 ]: The Azospirillum isolates were used wildtype isolate Aj Bandung 6. Natural association of Gluconacetobacter diazotrophicus and diazotrophic Acetobacter peroxydans with wetland rice. Abundant nodulation was found in black earth ”terra preta dos indios” and in one case on sandy soil under campinarana vegetation along a tributary of the upper Rio Negro.

Ed indicate that nitrogen fixation did occur in association with roots in some soils, but not with roots of primary or secondary forest on clayey latosol in the vicinity of Manaus, which is the most common soil in Central Amazonia. Influence of Azospirillum spp. The activity of antimicrobial agents was determined using diffusion and microdiluthion methods. The two bacteria produced large amounts of volatile compounds, including CO2, and the known plant growth-promoting volatile 2,3-butanediol and azowpirillum.

Inoculation of maize with Azospirillum brasilense in the seed furrow.

Application of inorganic fertilizer continuously can reduce soil microbial abundance. Two chromosomal regions with their putative att sites were previously identified as prophages in the genome of Azospirillum sp. B may degrade and use the aliphatic amine methylamine as a nitrogen source.
