一种搅拌式与气升式联用生物反应器及其在鼠李糖胶制备中的应用
摘要：
本发明公开一种搅拌式与气升式联用生物反应器，该装置由搅拌式反应器部分与气升式反应器部分组成，两部分通过恒流泵相连接进行物料交换。搅拌式反应器部分，由搅拌式反应器、pH自动控制装置和补料装置、第一通气装置及搅拌装置组成；气升式反应器部分，由气升式反应器、恒温水浴及第二通气装置组成。本发明还公开了上述搅拌式与气升式联用生物反应器在鼠李糖胶发酵制备中的应用。利用本发明的装置及工艺，鼠李糖胶生产强度高、产物浓度高，有利于实现工业化，是一种高效的生产方法。
摘要（英）：

The invention discloses a stirring-type and air-lifting combined bioreactor which consists of a stirring-type reactor part and an air-lifting reactor part, which are connected with each other through a constant-current pump so as to exchange materials. The stirring-type reactor part consists of a stirring-type reactor, an automatic pH control device, a replenishing device, a first ventilation device and a stirring device; and the air-lifting reactor part consists of an air-lifting reactor, a constant-temperature water bath and a second ventilation device. The invention also discloses an application of the stirring-type and air-lifting combined bioreactor in fermenting and preparing the rhamnose gum. By utilizing the device and the process, the production intensity of the rhamnose gum is high, the product concentration is high, industrialization can be realized, and an efficient production method can be realized.
