摘要: 本文利用气升式发酵罐研究了黄原胶的发酵工艺。在分批发酵的基础上,根据黄原胶发酵类型的特点,提出了两步补糖发酵黄原胶的新工艺,并在50L气升式发酵罐中进行了验证,经过比较证明在原有工艺的基础上,新工艺能提高发酵的产胶率和发酵液的粘度。

Abstract: In this article, fermentation condition of Xanthan Gum in airlift fermentor was studied. According to its characters, anew method was proposed by adding sugar with two-step on the basis of batch fermentation, and result was tested in 50L airliftfermentor. It showeds that the new method would benefit the yield and fluid viscocity.

Key words: Xanthan Gum, batch fermentation, two-step fermentation
