Abstract
Klebsiella oxytoca isolate 15 was isolated from the grounds of a nitra tion factory and was found to be tolerant to nitrate at concentrations up to 0.5 to 1 M. Physicochemical parameters for optimal growth condi tions for K. oxytoca isolate 15 were established. Growth took place wh en the nitrate concentration in the medium was less than 150 mM, and f ull nitrate consumption required about 14 g of C per g of N. This stra in was able to remove nitrate without accumulating nitrite. The system was scaled up to a 40-liter pilot plant and was operated on-site sati sfactorily.
