Fig. 2From: Genetic engineering of Synechocystis PCC6803 for the photoautotrophic production of the sweetener erythritolEffect of extracellular erythritol on growth of Synechocystis. Growth curve of wildtype Synechocystis, cultured in the presence of 0, 1, 10, 20, 30, 50 or 95 g/l meso-erythritol. Cells were grown under high intensity red/blue-light illumination (~70 μE/m2/s) in BG-11 supplemented with 10 mM TES-KOH (pH = 8) and 50 mM NaHCO3 at 30 °C.
