Table 3. REML output for (A) models testing effects of ¹⁵N concentration (at%; fixed effect) on the lag phase duration (λ, h), maximal growth during exponential phase (μ, d⁻¹) and AUC for well-specific growth curves over 119 h in the test system. Plate was a random effect in each model, and (B) LSD pairwise comparisons. Significant p-values are indicated in bold.
