Figure 2.

Solution of eqs 1a to 1c at steady-state. The figure is a close-up snapshot of the last 100 s in Figure 1 at which the system has reached steady-state. Based on size of droplet (0.1 mL), volume of chemostat (2 L), and the dilution rate (r_D = 0.009 hr^–1) the droplet frequency is calculated as one drop per every 20 s. The smoothing interval is assumed 5 s. For this setup, the results at steady-state are averaged as δ¹³C = 5.4 ± 0.2‰, ¹²S = 20.66 ± 0.6 μg/L, X = 550.74 ± 0.01 μg/L.
