Cyanobacterial production of erythritol. Growth and extracellular erythritol production of wildtype Synechocystis (WT) and mutants SEP007 (a), SEP013 (b), SEP016 (c), SEP021 (d). Solid symbols represent OD730, whereas open symbols depict the erythritol concentration. Error bars represent SD (n = 2). Genetic representation shows the inserted genes for the mutants, represented as arrows (not to scale). The light grey bar in front of tm1254 represent the decahistidine tag, whereas the dark and light grey short arrows represent the trc1 and the cpcBA promoter, respectively
