CONCLUSION
In this study, xylAB operon was introduced into C.
glutamicum SO26 to achieve the consumption of xylose for the production
of L-ornithine. And then, we verified the AraE, the reduction in the
degree of acetylation and the release of feedback inhibition of aspartic
acid of PEPC, the addition of biotin and thiamine hydrochloride, the
resulting strain C. glutamicum XAB03 has reached 41.5 g/L shaker
flask output from glucose and xylose. This work also shows the
possibility of making full use of lignocellulose for the synthesis of
L-ornithine and lays the foundation for the further realization of
industrialized strain production.
