Ammonium‐nitrogen assimilation and nitrogen fixation in azospirillum lipoferum and azospirillum brasilense

Acta Biotechnologica, 1990
AbstractThe effect of ammonium nitrogen on the growth and efficiency of nitrogen fixation by A. lipoferum and A. brasilense grown under various growth conditions was investigated.

Interaction of Azospirillum and Mycorrhiza

2015
The 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 ...

Isolation and properties of Azospirillum lipoferum and Azospirillum brasilense surface polysaccharide mutants

1989
Polysaccharide production by Azospirillum strains was indicated by fluorescence on growth media containing calcofluor. Mutants showing decreased and increased levels of fluorescence were obtained from A. lipoferum strain Sp59b by chemical mutagenesis, and from A. brasilense strain 7030 by Tn5 mutagenesis.

Advances in the Genetics of Azospirillum

1985
Bacteria 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 ...

Azospirillum-Plant Interaction

2014
Bacteria of the genus Azospirillum (alpha-proteobacteria) have been known for many years as plant growth-promoting rhizobacteria (PGPR) (Döbereiner and Day 1976). These free-living nitrogen-fi xing highly motile bacteria can be isolated from the rhizosphere of many grasses and cereals under tropical and temperate climates (Döbereiner et al.

?????????????????????? ???????????????????????????? ???????????????? ???????? azospirillum ?? ???????????????????? ??????????????????, ?????????????????????????????? in vitro

2011
Bacteria of Azospirillum genus, introduced into root zone of cultivated in vitro potato plants, cause the intensive plant development. Paranodules, observed on roots, do not reveal the nitrogenaze activity. Azospirillum bacteria have been developed in cells and intercellular space of the nodule parenchyma.
