ABSTRACT:
The action of the bacterium Nitrobacter agilis to oxidize nitrite ions to nitrate ions in aqueous solutions is well known. We have found that if the nitrite ion concentration in solution is maintained at a level of at least 2.5 percent by weight and higher, that the activity of this bacterium is completely inhibited and the nitrite salt solutions remain stable over long periods of time.
