    The Microbiological Inhibition Testing Procedure was developed to determine the possible adverse effects of specific compounds or waste waters on biological treatment processes. The test procedure consists of monitoring the oxidation rate of a biological seed at various dilutions of the waste water in BOD bottles. The threshold inhibition level of a compound or waste water is defined as the lowest concentration of the compound or waste water which causes a reduction in the biological oxidation rate.
