The result showed that when sucrose as carbon source,peptone or peptone plus beef paste as nitrogen source,original pH 6.0,the GABA production of As-8 strain could reach higher yield(4.2g/L) and was genetic stable after growing up to 15 generations.

• 菌株As-8转化富集GABA的适宜条件为:pH 6.；以蔗糖为碳源；蛋白胨为唯一氮源或蛋白胨和牛肉膏为复合氮源。 产生的GABA含量最高可达4；
