谷氨酸棒状杆菌(Corynebacterium glutamicum)是兼性好氧菌,为革兰氏阳性 。可用于微生物发酵工程生产谷氨酸来制取谷氨酸钠(味精),谷氨酸棒状杆菌在发酵过程中要不断地通入无菌空气,并通过搅拌使空气形成细小的气泡,迅速溶解在培养液中(溶氧);在温度为摄氏30到37度,pH为7到8的情况下,经28到32小时,培养液中会生成大量的谷氨酸。在谷氨酸生产中,培养基中碳氮比为4:1时,菌体大量繁殖而产生的谷氨酸少;当碳氮比为3:1时,菌体繁殖受抑制,但谷氨酸的合成量大增。在发酵过程中,当pH呈酸性时,谷氨酸棒状杆菌就会生成乙酰谷氨酰胺;当溶氧不足时,生成的代谢产物就会是乳酸或琥珀酸。
