Fig. 3From: Genetic engineering of Synechocystis PCC6803 for the photoautotrophic production of the sweetener erythritolPhotoautotrophic production of erythritol by an engineered cyanobacterium. a Growth and extracellular erythritol production of wildtype Synechocystis (WT) and mutant SAW030. Solid symbols represent OD730, whereas open symbols depict the erythritol concentration. Error bars represent SD (n = 2). b CBB-stained SDS-PAGE showing Synechocystis soluble lysates of wildtype and the different erythritol-producing mutants and E. coli soluble lysates with overexpressed TM1254 (indicated with *), ErCm (ER >) and Gcy1p (#), respectivelyBack to article page
