A fermenting process for preparing L-glutamine with high producing features that on the basis that xanthous brevibacterium has short fermenting period, the traditional enriching culture method is used for screening the resistance bacteria to obtain high-yield dominant bacterial strain. In the fermentation, a control method is disclosed to ensure that the femrentation has high yield. 本发明提供一种高产能的L-谷氨酰胺发酵方法，是在黄色短杆菌发酵周期短的基础上，经过潜心研究，把传统的富集培养法运用于抗性菌筛选中，高效率的选育出产能强的优势菌株，又在发酵中以最大的限度强化和保持菌体产酸能力为中心提出一整套保证发酵产能高的发酵控制方法，具有发酵周期短，发酵产率高等特点。
