| Abstract: | The Freeze-drying preservation（Freeze-drying）was adopted to preserve Brevibacterium glutamicum TG866.The results showed that the survival rate of TG866 after Freeze-drying reduced slightly but varied not much.TG866 can better maintain the fermentability after Freeze-dried.So we can conclude that freeze-drying can preserve the strain of producing L-glutamic acid TG866 effectively. |
