[ Method ] A full factorial experiment was designed to compare the lysine fermentation of C. pek/nense in medium containing different concentrations of lanthanon. [ Result ] Low doses of lanthanum can promote the growth of C. pekinense and accumulation of metabolite lysine; optimization for distinct components of medium were obtained as 78 mg/L rare earth, 36 g/L glucose, 4.5 g/L beef extract, 20 g/L peptone by Matlab software. [Conclusion] The study initially deter- mined the optimum La＋ additive amount in C. pekinense culture medium and the optimum medium compositions for C. pekinense to produce lysine.展开更多
