专利申请CN200510122930.5提供了“一种促进微生物酶法合成谷胱甘肽的方法”，其中公开了一种利用微生物细胞进行酶法合成谷胱甘肽的技术。该方法通过构建培养重组大肠杆菌E.coli WSH-KE1细胞作为酶源，并在反应体系中直接添加低浓度的有机溶剂或表面活性剂，降低细胞外膜的通透性屏障，在三磷酸腺苷(ATP)存在下催化L-谷氨酸、L-半胱氨酸及甘氨酸合成谷胱甘肽，反应2小时谷胱甘肽合成量可达4.8g/L。细胞通透剂的加入可以显著提高微生物体内相关酶的利用率，但是会造成关键酶随底物的流失，导致固定化细胞可重复用作反应催化剂这一优势减弱。此外，反应体系中需要添加大量ATP，ATP价格较昂贵，因此该方法用于工业生产的可行性不高。Patent application CN200510122930.5 provides "a method for promoting the enzymatic synthesis of glutathione by microorganisms", which discloses a technology for enzymatically synthesizing glutathione by microbial cells
