Calcium Requirements of Azotobacter

Nature, 1957
Calcium was essential for the growth of A. vinelandii, A. chroococcum, A. beijerinckii and A. insigne in the presence and absence of combined nitrogen. A. agile and A. macrocytogenes were able to grow in the absence of calcium but growth was stimulated by the cation. Calcium could be replaced by strontium at roughly the same molar concentration.

Derepression of nitrogenase in Azotobacter

Biochemical and Biophysical Research Communications, 1974
Abstract When nitrogenase in Azotobacter vinelandii 12837 is repressed by ammonia, the derepression is accelerated by endotoxin or cyclic AMP. The phenomenon appears neither to be a consequence of accelerated ammonia utilization nor altered activity of preformed enzyme. This is a unique example of an effect of endotoxin on a procaryotic system.
