Stable growth-coupled acetate production in a Synechocystis ∆acs mutant. Photonfluxostat cultures at different light intensities per biomass concentration reveal the proportionality between biomass-specific acetate productivity and growth rate (a). Steady states maintained in four independent turbidostat replicates display constant growth rate (b) and biomass-specific acetate productivity (c) for over 1 month of cultivation. Dry weight in a was calculated based on OD₇₃₀ measurements using a conversion coefficient of 148 mg L⁻¹ OD ⁻¹₇₃₀ previously determined for this setup [41]. Each filled circle in a represents a single observation, while gray shaded area in b and error bars in c indicate the standard deviation from four biological replicates
