Bioremediation of monobromoacetic acid, a haloacetic acid, continues to be recommended as acheaper and achievable method in comparison to physical and chemical techniques. In a priorwork, we model the growth of the bacterium Moraxella sp. B on monobromoacetic acid frompublished literature to acquire crucial growth constants. We learned that the Buchanan-threephasemodel via nonlinear regression using the least square method was the most effective model to describe the growth curve. Nevertheless, the use of statistical tests to choose the best model relies heavily on the residuals of the curve to be statistically robust. More often than not, the residuals must be tested for conformation to normal distribution. In order for these assumptions to be met, we perform statistical diagnosis tests such as the Kolmogorov-Smirnov, Wilks-Shapiro and D'agostino-Pearson tests.
