| Abstract: | Ectoine is synthesized by using halotolerant bacteria SL07 within a 30 liter fermenter. The optimal medium is selected. In the process of fermentation, the eetoine yield is elevated by adjusting the pH value. Under permanent pH, the ectoine yield is reduced by 10%, with salt adding; and improved by 43%, with peptone adding. After the first batch, the bacteria can be reused and the yield is elevated by 40% compared with that in the previous batch. |
