Epigenetic effects influence the decision making of L. lactis cells. Comparison of population growth rate after the switch point for populations precultured in CDM with cellobiose (blue dots and line) and those precultured in CDM containing glucose (red dots and line) is shown. A higher fraction of cellobiose precultured cells switch to cellobiose consumption after the switch point for all initial glucose concentrations tested compared with glucose precultured cells (df = 17; R² = 0.7877; P_{initial glucose conc.} = 9.407 × 10⁻⁷; P_{preculture effect} = 0.014).
