Figure S5. Confirmation of exponential growth before the downshift.

Each growth curve represents a biological replicate. Two samples from each of these cultures were filtered separately and placed into two separate flasks, one experiencing the downshift and one without downshift, as shown in Fig 3 in the main text. The growth rate is obtained by an exponential fit to these growth curves and the results are shown in Table S1. The OD₄₃₆ is the optical density of the culture measured at the wavelength of 436 nm, which reflects bacterial growth.
