Fructose catabolism in Azospirillum brasilense and Azospirillum lipoferum [PDF]
Journal of Bacteriology, 1984 The pathways for catabolism of fructose were investigated in the type strains of Azospirillum lipoferum and Azospirillum brasilense grown aerobically with (NH4)2SO4 as the nitrogen source. When grown on fructose, the former species possessed a complete Entner-Doudoroff pathway, whereas the latter species lacked activity for glucose-6-phosphate ...

Journal of the World Aquaculture Society, Volume 53, Issue 6, Page 1101-1119, December 2022., 2022 Abstract In laboratory and industrial cultivation of marine microalgae, it is customary to enrich cultures with macronutrients (N, P), chelated trace metals, and vitamins at ~104× concentrations found in nature to obtain high culture densities. Other naturally occurring growth‐promoting compounds found in local seawater are not enriched and remain at ...

Flocculation in Azospirillum brasilense and Azospirillum lipoferum: exopolysaccharides and cyst formation [PDF]
Journal of Bacteriology, 1985 The phenomena of flocculation and floc formation by Azospirillum brasilense Sp7 (ATCC 29145) and Azospirillum lipoferum Sp59b (ATCC 29707) were studied in aerobic liquid cultures. Carbon sources representative of various entry pathways in combination with various nitrogen sources induced flocculation in both species of azospirilla.

Regulation of nitrogenase activity by oxygen in Azospirillum brasilense and Azospirillum lipoferum [PDF]
Journal of Bacteriology, 1987 The nitrogenase activity of the microaerophilic bacteria Azospirillum brasilense and A. lipoferum was completely inhibited by 2.0 kPa of oxygen (approximately 0.02 atm of O2) in equilibrium with the solution. The activity could be partially recovered at optimal oxygen concentrations of 0.2 kPa.
