dc.description.abstract | A glucose-inducible gene expression system has been developed using HexR-Pzwf1 of Pseudomonas putida to induce the metabolic pathways. Since the system is controlled by an Entner–Doudoroff pathway (EDP) intermediate, the EDP of Escherichia coli was activated by deleting pfkA and gntR genes. Growth experiment with green fluorescent protein as a reporter indicated that the induction of this system was tightly controlled over a wide range of glucose in E. coli without adding any inducer. 2,3-butanediol (BDO) synthetic pathway genes were expressed by this system in the pfkA-gntR-deleted strain. The resultant engineered strain harbouring this system efficiently produced BDO with a 71% increased titer than the control strain. The strain was also able to produce BDO from a mixture of glucose and xylose which is comparable to glucose alone. Further, the strain produced 11 g/L of BDO at a yield of 0.48 g/g from the hydrolysate of empty palm fruit bunches. This system can also be applied in many other bio-production processes from lignocellulosic biomass. | - |
