Nitrate Ion-Selective Electrode in Microbial Media

Manahan, Stanley E.

RESUMO

A nitrate ion-selective electrode has been used to follow the kinetics of the reduction of nitrate by a bacillus isolated from the rumen of a sheep. The electrode system and the microbial culture were found to be quite compatible, although the formation of nitrite limits the utility and precision of the measurement. The formation of nitrite was followed simultaneously by a colorimetric method. Nitrate was converted quantitatively to nitrite. The rate of the reaction was found to increase to a plateau value, then drop abruptly when the nitrate was exhausted.
