文摘
- •
It is confirmed that K+ presents a marked impact on γ-PGA production.
- •
K+ can effectively increase γ-PGA yield and reduce broth viscosity.
- •
The D-/L-glutamate ratio and Mw of γ-PGA are regulated by K+.
- •
Enhanced GDH, GOGAT, GLR and pgsB are important to improve the γ-PGA yield.
- •
Provide a potential simple control strategy for γ-PGA production.
