AZOSPIRILLUM HALOPRAEFERENS
| Class: | Alpha Proteobacteria |
| Genus: | Azospirillum |
| Species: | Azospirillum halopraeferens |
| Description: | Azospirillum halopraeferens,a Nitrogen-Fixing Organism Associated with Roots of Kallar Grass (Leptochloa fusca (L.) Kunth) . Cells are vibrioid to S shaped, are motile by one polar flagellum, and produce granules of poly-β-hydroxybutyrate. They have a respiratory type of metabolism, show microaerophilic growth when fixing nitrogen, grow well on salts of organic acids, and can also use fructose and mannitol. On nitrogen-free semisolid media, they require biotin, utilize mannitol, but not glucose or sucrose, and cannot acidify glucose aerobically or anaerobically. Optimal growth occurs at 0.25% NaCl and 41°C. |
