Modeling of Scale-Dependent Bacterial Growth by Chemical Kinetics Approach

Figure 2

Series of EPEC growth experiments with SA = 1.0 cm² and V=1.0 to 2.5 cm³ corresponding to SA/V = 0.4 to 1.0 cm⁻¹ (open circles) best fitted by the CKA model (solid lines). (a) Fitting of each growth curve independently with obtained values for 𝑘₀ to 𝑘₄ according to Table 2. (b) Only fitting of 𝑘₃ at fixed 𝑘₀=6.46 M⁻¹s⁻¹, 𝑘₁=5.99×10⁻⁵ s⁻¹, 𝑘₂=2.18×10⁻¹ M⁻¹s⁻¹, and 𝑘₄=4.18×10⁸ M⁻¹. Obtained values for 𝑘₃ at different (SA/V): 1.29×10⁻⁵ (0.50), 6.18×10⁻⁵ (0.57), 1.07×10⁻⁴ (0.67), 2.97×10⁻⁴ (0.80), and 4.53×10⁻⁴ (1.00) s⁻¹. Initial concentrations: [B]=4.0×10⁻⁸, [O₂] =1.0×10⁻⁴, and [N] = 0.8 M, all others at zero.
