A microbial electrode was constructed with immobilized nitrifying bacteria and an oxygen probe to examine the inhibition of chemicals on respiration. Substrates for ammonia and nitrite oxidizers were introduced into the flow cell of the electrode according to M-series and anti-symmetric M-series pseudo-random binary signals. The respiratory responses of the bacteria were obtained by calculating the cross-correlation function between the input and the output signals. The inhibition effects were measured by the decrease of the responses due to the addition of inhibitor such as allylthiourea and chlorate. The method allowed us to evaluate the effects of inhibitor on ammonia and nitrite oxidizing bacteria simultaneously.
