中文摘要 | The effects of sucrose on cell growth and nisin production by Lactococcus lactis were investigated in batch and pH feed-back controlled fed-batch cultures. In batch cultures, nisin titer reached its maximum, 2658 IU cm(-3), at the initial sucrose concentration of 30 g dm(-3). With sucrose concentrations higher than 30 g dm(-3), nisin production decreased while the biomass was not influenced significantly. By using the pH feed-back controlled method, residual sucrose concentration could be controlled well in fed-batch cultures and three conditions (sucrose maintained at 2, 16, 20 g dm(-3), respectively) were evaluated. Maintaining a low sucrose concentration at 2 g dm(-3) during feeding favored nisin biosynthesis, and the maximum nisin titer obtained was 4961 IU cm(-3) compared with 3370 IUcm(-3) (16g sucrose dm-3)and 3498 IU cm(-3) (20 g sucrose dm-3), respectively.
