Derepression of Nitrogen Fixation in Desulfovibrio gigas and its Stability to Ammonia or Oxygen Stress in vivo

open access: yesMicrobiology, 1984
SUMMARY: Nitrogen fixation (acetylene reduction) by Desulfovibrio gigas was displayed weakly and capriciously in lactate/sulphate media and sequential or continuous diazotrophic cultures were not successfully established. Washed cells from lactate-grown N-limited chemostat populations at 28 °C showed reproducible anaerobic derepression of acetylene ...
