Ammonia reversibly inhibits the nitrogenase activity not only in purple nonsulfur bacteria but in purple (Thiocapsa roseopersicina) and green (Chlorobium limicola forma thiosulfatophilum) sulfur bacteria as well. The complete inhibition of nitrogenase activity (acetylene reduction) is observed about 30 s after addition of NH 4 + (≥2.5×10-6 M) to cell… CONTINUE READING
