Abstract

Various heterotrophic nitrifiers have been tested and found to also be aerobic denitrifiers. The simultaneous use of two electron acceptors (oxygen and nitrate) permits these organisms to grow more rapidly than on either single electron acceptor, but generally results in a lower yield than is obtained on oxygen, alone. One strain, formerly known as “Pseudomonas denitrificans”, was grown in the chemostat and shown to achieve nitrification rates of up to 44 nmol NH3 min−1 mg protein−1 and denitrification rates up to 69 nmol NOinf3sup−1min−1 mg protein−1.

Unlike Thiosphaera pantotropha, this strain needed to induce its nitrate reductase. However, the remainder of the denitrifying pathway was constitutive and, like T. pantotropha, “Ps. denitrificans” probably possesses the copper nitrite reductase.
