Abstract
Nitrobacter agilis
was entrapped in calcium alginate beads and used as a floating bed supplied with a continuous flow of nitrite medium. Complete nitrite oxidation was achieved within 30 h, and the system could be maintained for at least 210 h. The immobilized
Nitrobacter
system was subjected to sulfur oxyanions, acidity, and metal ions. Thiosulfate and tetrathionate (up to 20 mM each) did not inhibit the nitrite oxidation activity. A low pH of 4.2 resulted in the complete cessation of nitrite oxidation, and the activity was not restored upon increasing the pH to 7. Nitrite oxidation by
N. agilis
was sensitive to 10 mM each Ni
2+
and Al
3+
but insensitive to 10 mM MoO
