Table 1: Values of growth parameters (106 cell·mL−1) and (day−1) obtained by fitting logistic model equation to experimental data of population density in function of time from selenium exposed culture and control. Model curve was fitted to mean values of population density data (see Figure 1); hence, fitted models give single parameters values, instead of and mean values ± S.D.
