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.

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

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 ...

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.

Interaction of Azospirillum and Mycorrhiza
2015The AM fungi interact with Azospirillum directly by providing niche and/or habitat or indirectly by modifying host plant morphophysiology. This communication in soil can be beneficial for both the microorganisms and the host plant. The Azospirillum inoculation is more successful and more profitable when other microorganisms are co-inoculated with ...

Advances in the Genetics of Azospirillum
1985Bacteria of the genus Azospirillum are diazotrophs associated with the root of grasses, without formation of differentiated structure. Very little is known on the genetics of these bacteria and on the molecular biology of their association with plants. The bacteria, first described in 1922 by Beijerinck and rediscovered in 1963 by Becking, were called ...
