AZOTOBACTER SALINESTRIS
| Class: | Gamma Proteobacteria |
| Genus: | Azotobacter |
| Species: | Azotobacter salinestris |
| Description: | Were absolutely dependent on Na+ ions for growth and frequently used melibiose as a carbon and energy source. Aerobically grown cells were melanized dark brown to black; the cells were large, gram negative, oval with pointed ends, and motile by means of peritrichous flagella and formed pairs and chains of six to eight cells during active growth. Capsule production was variable. Nitrogen fixation by A. salinestris occurred optimally at 35°C in the presence of molybdate or vanadate ions in a microaerophilic, aeroadaptive manner. |
