| Since we found a significant change in growth of suspension cells (Fig. 3). The cell number was in a lower level before 4 h, but then rapidly raised with high budding rate and low mortality rate. When fermented for 16 h, the cell number achieved a maximum value of about ? million/mL, which was closed to industrial level. However, increased ethanol exhibited a strong inhibition on yeast cells in the later period of fermentation, which led to a low budding rate and high mortality rate, thereby showing a decreased tendency in cell number. In addition, after 11 batches, a layer of enriched cells was observed in some place of carrier surface with the naked eye, which was not in consistent with Choi et al. who reported that it was difficult to accumulate cells through repeated batch processes. This result indicated that cell immobilization can promote cell growth and not seriously affected by sludge and suspended solid in the cassava meal medium. |

...,since we found a significant change in growth of suspension cells (Fig. 3). From the figure, we can see that the cell number is in a lower level at the first 4 hours of the fermentation. But, subsequently, the number raises rapidly due to the high budding rate and low mortality rate. Finally, the number reaches the maximum value #/mL, which approaches the level of industrial production, at the time 16 hours after the beginning of the fermentation. However, this is not a real ending. As time goes futher, the number trends to decrease because of the increase of ethanol. The rise of ethanol has a strong inhibition on yeast cells, and therefore results in a low budding rate and high mortality rate. In addition, after 11 batches, a layer of enriched cells is visible in some place of carrier surface. This is not in consistent with the results of Choi et al. [] which suggest(show, reveal, indicate) that it was difficult to accumulate cells through repeated batch processes. Our results suggest that cell immobilization can promote cell growth. The results also indicate that the cell growth is not seriously affected by sludge and suspended solid in the cassava meal medium. |

我來試試看: A significant change in growth of suspension cells was observed. The cell number was in a low level in the first 4 hours, then rose with high budding rate and low mortality rate. After 16 hours fermentation, the cell number reached a maximum of about million/mL which is close to the industrial level. However, increase of ethanol caused a strong inhibition on yeast cell growth, leading to a low budding rate and high mortality rate, as a result, the tendency in cell number decreased. In addition, a layer of enriched cells was observed with the naked eye in some places of the carrier surface, this is not in consistent with the work reported by Choi. In their work, it was demonstrated that it was difficult to accumulate cells through repeated batch processes. Therefore, this result in our work indicated that cell immobilization can promote cell growth and it is not seriously affected by sludge and suspended solid in the cassava meal medium. |

中文:。。。因為我們發(fā)現(xiàn)懸浮細胞生長有明顯的變化。在發(fā)酵4小時前,細胞數(shù)處于極低的水平,但隨后伴隨著高出芽率和低死亡率而迅速上升。當發(fā)酵16小時時,細胞數(shù)達到最大值?億個/mL, 接近了工業(yè)發(fā)酵的水平。但是,在發(fā)酵后期,乙醇濃度的升高對酵母細胞發(fā)揮了較強的抑制作用,導致低出芽率和高死亡率,從而表現(xiàn)出細胞數(shù)減少的趨勢。另外,在發(fā)酵11批后,在載體某些表面可以用肉眼看到少量菌體富集的現(xiàn)象,這與Choi等人報道的不是很相符,在他的研究中,他發(fā)現(xiàn)酵母細胞在間歇式發(fā)酵中很難積累。這個結(jié)果表明,細胞固定化可以促進細胞生長,(細胞生長)不會受到木薯粉發(fā)酵培養(yǎng)基中的污泥和懸浮固體嚴重影響。 |
