摘要: 比较了胀果甘草( Glycyrrhiza inflata) 悬浮细胞在逐级放大摇瓶中的生长、黄酮产量以及营养消耗过程, 以便了解其放大规律。结果表明, 在250 和500 mL 摇瓶中, 细胞的最大生物量、黄酮产量以及最大比生长速率没有显著性差异, 但是在1 L 的摇瓶中, 这三种参数都显著地降低, 分别比250mL 摇瓶中降低了27% , 30%和27%。在逐级放大的摇瓶中, 氮、磷、铵浓度都随着培养时间延长而逐渐降低, 尽管在1 L的摇瓶中磷消耗得最慢, 但三种摇瓶中磷在细胞生长对数期基本都被消耗尽了。此外, 硝态氮在第18 天时基本被消耗完, 而铵态氮在细胞收获时仍能维持在100 mg􊄯L。因此在反应器中培养时, 主要的培养条件还需进一步优化。

Abstract: The cell biomass, flavonoids production and nutrients consumption were monitored to characterize the culture of progressive scale-up of Glycyrrhiza inflata . The maximum biomass, flavonoids production and the maximum specific growth rate in the culture of 250 and 500mL flasks remain similar , but were significantly higher than that of 1 000 mL flask. The three parameters in the culture of 1 000mL flask were 27% , 30% , and 27% lower than that of 250 mL flask , respectively. The concentrates of phosphate , nitrate and ammonium in progressive scale-up flasks decreased similarly . Phosphate and nitrate were almost exhausted on day 10 and 18 in all flasks, respectively; while ammonium maintained about 100mg/L till cells were harvested. The basic culture conditions needed to be further optimized for higher flavonoids production on a bioreactor scale .
