The invention belongs to the technical field of amino acid production, and discloses a green and clean fermentation technology of glutamic acid. The method comprises the steps that corynebacterium glutamicum is inoculated into a fermentation tank containing a clean fermentation culture medium to perform fermentation culturing, and auxiliary ultrasonic treatment is conducted. The technology has theadvantages that the fermentation efficiency is improved, and the separation difficulty of the glutamic acid is reduced. 本发明属于氨基酸生产技术领域，公开了谷氨酸的绿色清洁发酵工艺，其将谷氨酸棒杆菌接入装有清洁发酵培养基的发酵罐中进行发酵培养的步骤，并且辅助超声波处理。本发明工艺提高了发酵效率，降低了谷氨酸分离的难度。
