Temperature inhibition of siderophore production in Azospirillum brasilense [PDF]

Journal of Bacteriology, 1989
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 ...

EFFECT OF NITROGEN FIXING ASSOCIATIVE DIAZOTROPHS ENCAPSULATED IN ALGINATE OR FREE CELL SYSTEMS INOCULATION ON SEED GERMINATION AND GROWTH OP SOME VEGETABLE PLANTS [PDF]

Journal of Agricultural Chemistry and Biotechnology, 2005
A laboratory experiment was carried out to study the effect of inoculation with some non-symbiotic nitrogen fixing diazotrophs (Azospirillum liopferum, Azospirillum brasilense, Azotobacter chroococcum) in addition to Bacillus polymyxa either each in free

Contribution of Azospirillum brasilense to nitrogen fertilization for maize crops planted successively to soybean crops

Revista Agrogeoambiental, 2023
Maize is very important in Brazilian agribusiness: it is the second most produced grain in the country. Crops need to be fertilized, especially with nitrogen, to achieve high yields.

Technical and economic viability of co-inoculation with Azospirillum brasilense in soybean cultivars in the Cerrado

Revista Brasileira de Engenharia Agrícola e Ambiental
Biological nitrogen fixation (BNF) efficiency can be increased by co-inoculation with bradyrhizobia and Azospirillum brasilense, allowing even greater uptake of water and nutrients, leading to higher yields.

Seed treatments with salicylic acid and Azospirillum brasilense enhance growth and yield of maize plants (Zea mays L.) under field conditions

Revista de la Facultad de Ciencias Agrarias, 2023
Salicylic acid and Azospirillum brasilense stimulate plant growth and productivity. In some environments, plant physiology similarly responds to both bioactive products.

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

Coinoculation of Bradyrhizobium and Azospirillum to Mitigate the Effects of Drought Stress in Soybean Plants

New Zealand Journal of Agricultural Research, Volume 69, Issue 4, August 2026.
Bacteria of the genus Azospirillum have been used to mitigate negative effects of drought stress. Since there is few information on interaction of new strains of A. brasilense and soil water status, we evaluated the effects of coinoculation of A. brasilense strains (Ab‐V5/Ab‐V6 and HM053) on soybean plants grown either with (40% of field capacity) or ...

Investigation of Substrate Specificity in 5‐Keto‐4‐Deoxy‐Glucarate Dehydratase and 2‐Keto‐3‐Deoxy‐L‐Arabinonate Dehydratase

ChemBioChem, Volume 27, Issue 14, 29 July 2026.
5‐Keto‐4‐deoxy glucarate dehydratase and 2‐keto‐3‐deoxy‐L‐arabinonate dehydratase share many similarities like structure, reaction mechanism, and their generated product, but exhibit very high substrate specificity. Here, we explore the evolutionary development of this specificity in the context of the enzyme superfamily and attempt to find promiscuous

Coinoculação de Azospirillum brasilense e FMAs no desenvolvimento e teores de cobre em sorgo e milho cultivados em solo contaminado

Semina: Ciências Agrárias
A contaminação com cobre tem aumentado nos solos submetidos a aplicação de fungicidas e fertilizantes orgânicos, incluindo áreas sob cultivo de milho e sorgo. Os fungos micorrízicos arbusculares (FMAs) e bactérias Azospirillum brasilense evidenciaram-se
