Abstract:  Orthogonal design and uniform design were used to optimize the medium for L-ornithine fermentation, and the experimental results were analyzed by Data-processing System (DPS). The optimum medium for the production of L-ornithine by Arthrobacter paraffineus WZFF. X-164 was established and confirmed. The result indicated that DPS had a satisfactory effect on optimizing the medium for L-ornithine fermentation and that the yield reached 19.91g/L by increasing the productivity for more than 125%.
