摘要
本文以ＡＳ．１５６３谷氨酸棒杆菌为生产菌种，通过摇瓶发酵研究了生物素、苏氨酸、蛋氨酸三种生长因子对赖氨酸产量的影响。实验结果表明，三种生长因子用量不同对赖氨酸产量均有明显影响（Ｐ＜０．０５或Ｐ＜０．０１）。通过正交实验分析，三者在发酵培养基中的最佳用量配合为：苏氨酸５００ｍｇ／Ｌ、蛋氨酸２００ｍｇ／Ｌ、生物素３５０ｍｇ／Ｌ。
Effects of three growth factors (biotin,threonine and methionine)on lysine production of AS.1563 Cornebacterium glutamicum by shake culture.The results showed that different levels of the factors had significant effects on lysine production(P<0.05 or P<0.01).Optimum proportion of the three factors analyzied by orthogonal experimental method were 500mg/L threonine,200 mg/L methionine and 350mg/L biotin.
