Characterization of a temperate bacteriophage for Azospirillum
Virology, 1982Abstract A temperate bacteriophage, forming plaques on Azospirillum lipoferum strain Br17, was isolated from Brazilian soil samples. The phage morphology as revealed by electron microscopy showed an icosahedral head of 56 nm and a tail of 250 nm, to which six spikes are attached. The phage genome is double-stranded linear DNA of 36 kb with cohesive

Phylogenetic Studies of the Genus Azospirillum
1995The 16S rDNA of seventeen Azospirillum strains, fourteen of which assigned to one of known A. amazonense, A. brasilense, A. halopraeferens, A. irakense and A. lipoferum species, and other three of uncertain taxonomic collocation, was sequenced and analysed after polymerase chain reaction amplification, in order to investigate the phylogenetic ...

The ability of Azospirillum to colonize the roots of plants depends on motility and chemotaxis. Azospirillum cells are motile and capable of chemotaxis toward organic acids, sugars, and some aminoacids. Azospirillum is also able to navigate gradients of oxygen, alternative electron acceptors, and redox active compounds.

Use of new strain of nitrogen fixing bacteria Azospirillum sp. 77 for inoculation of spring wheat and spring triticale permitted to form an effective associative system diasotroph ??? plant. The bacterization promoted the reliable increase of potential nitrogenase activity in root zone of plant by 38-220 %, activated the biosynthetic processes, in ...

Pleomorphism in azospirilla appears to be induced by medium composition rather than pH. Complex organic media stimulate it and it is more pronounced in Azospirillum lipoferum than in A. brasilense. Besides ‘capsules’, protoplasmic globular structures (free protoplasts) sometimes may be produced. Under certain conditions the smaller cells appear to have

Inoculation of millet with azospirillum
Plant and Soil, 1979Millet plants (Pennisetum glaucum) were grown at three levels of nitrogen fertilization with and without an inoculum of live nitrogen-fixing Azospirillum cells. The highest average rate of nitrogen fixation as estimated from acetylene reduction by excised preincubated roots was only 23g N2 fixed per ha per day and occurred after treatment with low ...

Inoculation of Zerna inermis with azospirilum bacteria results in associated nitrogen fixation activity increase and initiation of plant development. Specimens of Azospirilum brasilense only were settled down in root zone. A. lipoferum influence on parameters increase indirectly ??? due to physiologically active substances (PAS) of inoculums.

Polyhydroxybutyrate in Azospirillum brasilense
2015Polyhydroxybutyrate (PHB) is a polyhydroxyalkanoate produced by several bacteria as carbon storage and reductive equivalents sink. The production of PHB has been reported for several plant-associated bacteria, and especially in Azospirillum brasilense, the production of PHB has been associated as a factor for stress endurance.
