             ATCC 14997 谷氨酸棒状杆菌 百欧博伟生物

谷氨酸棒状杆菌（Corynebacterium glutamicum）是近四十年来全球用以氨基酸发酵工业的主要生产菌，早在1957年由Kinoshita首次描述其为谷氨酸产生菌。谷氨酸棒状杆菌在分类上属于革兰氏阳性真细菌下的放线纲棒状杆菌属。

谷氨酸生产

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30-37℃，pH为7到8的情况下，经28-32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。

主要价值

谷氨酸棒状杆菌是工业上主要的谷氨酸生产菌之一。该菌能够以葡萄糖、果糖、蔗糖以及一些有机酸如乙酸、乳酸、琥珀酸等为单一碳源生产谷氨酸。 

谷氨酸棒杆菌还是苏氨酸、赖氨酸的主要产生菌。
