Title:
連続発酵によるカダベリンの製造方法
Document Type and Number:
Japanese Patent JP5458479
Kind Code:
B2
Abstract:

To provide a method for producing cadaverine by a continuous fermentation method for stably maintaining high productivity under simple operating conditions, and over a long time.

This method for producing cadaverine by a continuous fermentation method comprises separating a culture liquid into a filtrate and a non-filtrated liquid with a separation membrane, recovering cadaverine of desired fermentation product from the filtrate, and then by holding or returning the non-filtrated liquid in the culture liquid. By using a porous membrane having a high permeability and a high cell-stopping rate and hardly occluded as the separation membrane and by subjecting the culture liquid to filtration treatment at low inter-membrane difference pressure, the fermentation production efficiency of cadaverine can be improved markedly, in a stable manner and at low cost.
