    Notes: The previously published (Palumbo et al. 1991) response surface model for describing the influence of temperature, pH, NaCl, and sodium nitrite on the aerobic growth of Aeromonas hydrophila K144 in BHI broth has been expanded to incorporate additional data. The effects of the variables on A. hydrophila aerobic growth kinetics were modeled by response surface analysis using quadratic and cubic polynomial models of (1) natural logarithm transformation of both the Gompertz B and M parameters and the lag phase duration (LPD) and generation time (GT), and (2) the square root transformation of B and 1/M calculated from 268 cultures (212 of which supported growth) from 81 variable combinations. In addition, the six models generated also were subjected to backward elimination regression analysis to remove nonsignificant variables. Based on examination of the adjusted R2 values of the resulting 12 models, three were selected for further evaluation by comparing their observed and predicted T1000-values (time for a 1000-fold increase in number; this concept incorporates the influence of the variables on both lag and generation times), LPDs and GTs. Using this method of comparison and evaluation, models based on cubic polynomial, natural logarithm transformation of GT and LPD gave the best “first estimates” of the aerobic growth characteristics of A. hydrophila.
