The statistical discrimination between two rival mathematical models has shown that the mechanism of non-specific substrate inhibition of respiration kinetics fits better the experimental data. It has been found that the maximum respiration activity is controlled by the buffering properties of organic polycarbonic acids in the medium. The pH values at which the maximum respiration rate was observed were close to the pK values of the organic acids in the buffer solution, independently of whether the acids were metabolized or not.
