The comparative analysis of growth and riboflavin production between strains overexpressing a synthetic operon and the control strain. (A) Presents the riboflavin production between BEX5 (BSR overexpression pEX5) and B13 (BSR overexpression pHP13 (spe)) during flask fermentation at 48Â h, with sucrose employed as the carbon source. (B) The growth curve of BEX5 and B13
