Recycling yield and maintenance rate per cell volume. (C) Recycling yields and (D) maintenance rate measured as described in Fig. 2 are normalized per cell volume and plotted versus the previous growth rate of the cultures they refer to (see color legend at the top and Table EV3). The normalized yield is constant within the uncertainty. Maintenance rate increases significantly with a slope of (0.99±0.55) h, matching the increase of the death rate, (1.1±0.4) h, shown in Fig 2B. Solid black lines show linear fits on log transformed data, using weighted least square fits.
