Construction of expression systems of PHB biosynthesis genes and PHB production A Schematic illustration of pABC for PHB biosynthesis genes expression in C. glutamicum B Comparison of PHB production levels of C. glutamicum harboring pABC in nutrient-rich (BHI) medium and in a minimal medium. Both media were supplemented with 2% glucose as a sole carbon source. C. glutamicum strain with an empty vector (pCES208) was used as a negative control. All measurements are based on two biological replicates. Error bars represent standard deviation of the biological replicates
