中文摘要 | Escherichia coli was metabolically engineered using a new host-vector system to produce phloroglucinol. The key biosynthetic gene phlD (encoding a type III polyketide synthase) from Pseudomonas fluorescens was expressed in E. coli using the stationary-phase promoter of the fic gene and a high-copy plasmid. In shake-flasks, the engineered strain produced phloroglucinol up to 0.28 g/l with a productivity of 0.014 g/l h. About 9.2% of the glucose consumed was converted to phloroglucinol after 20 h. Compared with the widely used inducible T7 promoter system, this strain did not require IPTG induction and the final titer of phloroglucinol was 22% higher. |
