The kinetic study of a microbial system requires the determination of kinetic parameters under a set of operating variables. Previous researchers indicated that initial conditions, such as S-o/X-o and S-o/K-s, may influence the reliability of the parameter estimation. However, little study has been done to identify the sensitivity of system variables to the parameter estimation. This study proposes a novel dimensional analysis and identifies six dimensionless groups: mu(m)/f(w), k(d)/f(w), Y-g, S-o/K-s, K-s/S-o, and 1/(f(w) theta(c) - 1). By incorporating the SP-moving algorithm proposed by Wu and coworkers in 2001, an algorithm was proposed in this study to perform a sensitivity analysis on the six dimensionless groups. Results of this analysis reveal that S-o/X-o, is more sensitive than S-o/X-o, as also evidenced by the fact that gross growth yield (Y-g) is sensitive and affecting S-o/X-o. The analysis also suggests that the theta(c)-based wasting frequency (f(w)theta(c)) is more sensitive than the daily wasting frequency (f(w)). A critical minimum value of 1.3 for S-o/X-o and a maximum value of 0.1 for S-o/K-o were suggested to establish the testing criteria for the kinetic study under the respirometric conditions.
