| additional information | metabolic engineering of Escherichia coli carrying the hybrid acetone-biosynthesis pathway for efficient acetone biosynthesis from acetate, simplified metabolic pathways of acetone biosynthesis by engineered Escherichia coli strain using acetate as carbon source under aerobic condition, overview. In the optimized hybrid acetone biosynthesis pathway, acetate is first converted into acetyl-CoA through ACS (acetyl-CoA synthetase) pathway or ACK-PTA pathway. Then, 2 mol of acetyl-CoA are condensed by thiolase to generate 1 mol of acetoacetyl-CoA. Acetoacetyl-CoA transferase transfers the CoA moiety from acetoacetyl-CoA to acetate, and forms acetoacetate and acetyl-CoA, which is part of endogenous acetate utilization pathway. Finally, acetoacetate is catalyzed to form acetone and carbon dioxide by acetoacetate decarboxylase. Construction of recombinant Escherichia coli strain MG1655 expressing the hybrid pathway consisting of thlA, atoDA, and adc, that produces high levels of acetone from acetate. Reducing the gluconeogenesis pathway has little effect on acetone production, while blocking the TCA cycle by knocking out the icdA gene enhances the yield of acetone significantly. As a result, acetone concentration increases up to 113.18 mM in 24 h by the resting cell culture coupling with gas-stripping methods. The engineered Escherichia coli strain with optimized hybrid acetone biosynthetic pathway can utilize acetate gas substrate efficiently to synthesize acetone without other non-gas byproducts | Clostridium acetobutylicum |
