气升式发酵罐发酵黄原胶的动力学

Fermentation Kinetics of Xanthan Gum in Airlift Fermentor

摘要:

利用黄单孢菌研究了在50L气升式发酵罐发酵黄原胶的动力学,在logistic方程和Luedeking Piret方程的基础上,建立了两步发酵黄原胶的动力学模型,并对模型和实验数据进行了比较,进一步在200L相似结构的气升式发酵罐中的试验表明,该模型能较好的对发酵动力学进行描述.

Abstract:

In this article, Xanthomonas campestris was used to study the two-step fermentation kinetics of xanthan gum in 50 liters airlift fermentor. The fermentation kinetic models were built on the basis of logistic and Luedeking-Piret equations. The kinetic
