During the stationary phase of fermentation, cell productivity was slightly reduced. MgSO_4 and tryptone have the positive effect on the product synthesis and cell growth respectively. Based on these conclusions, MgSO_4 and tryptone were added to the feed medium to enhance the production of polysialic acid. Variable feed rate policies were applied to the fed-batch fermentation process and the final biomass and polysialic acid production were both increased by 40 percent.

通过摇瓶实验研究了大肠杆菌发酵过程中菌体生长和产物合成的影响因素，结果表明：产物合成与菌体生长是相耦联的过程，菌体生长受到菌体代谢产物的抑制作用，聚唾液酸的合成不受代谢产物的抑制作用；发酵进入稳定期后菌体的生长和生产能力有所降低；硫酸镁和胰蛋白胨分别对产物合成和菌体生长有一定的促进作用。
