Aerotactic response of Azospirillum brasilense [PDF]
Journal of Bacteriology, 1982 Five strains of Azospirillum brasilense and two of Azospirillum spp., from Israel, responded to self-created and preformed oxygen gradients by forming aerotactic bands in capillary tubes and actively moving toward a specific zone with low dissolved oxygen.

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.
