微生物多不饱和脂肪酸发酵动力学

Fermentation Kinetic of Microbial Polyunsaturated Fatty Acids

分析了富含 γ-亚麻酸油脂发酵过程的代谢特点 ,建立了菌体生长、产物形成及底物消耗的动力学模型 ,对模型参数进行了估计 ,并对参数估计结果的合理性进行了分析。模型的拟合和预测结果表明 ,模型的计算值和实测值较为吻合 ,拟合的平均相对偏差小于 8.5%。

The metabolic characters in the fermentation processes for producing oils contatining γ linolenic acid were analyzed The kinetic models of cell growth, product formation and substrate consumption were established respectively The parameters of the models have been estimated by regression The calculated curves fit the experimental data quite well The result showed that the average relative deviation between calculation and measurement is less than 8 5%
