Effect of Oxygen on Formation and Activity of Nitrate Reductase in a Halophilic Achromobacter Species.

Abstract
Nitrate reductase was induced in cells of Achromobacter sp. when the bacteria were grown in an aerated nitrate-containing medium. Nitrate reduction was maximal in N2 atmosphere, decreased as the O2 content increased. It stopped completely when free O2 was registered in the suspending medium.
