Abstract
The glnZ mutant of Azospirillum brasilense (strain 7611) showed only partia l recovery (20 to 40%) after 80 min of ammonia-induced nitrogenase switch-o ff, whereas the wild type recovered totally within 10 min. In contrast, the two strains showed identical anoxic-induced switch-on/switch-off, indicati ng no cross talk between the two reactivation mechanisms.
