摘要：
A method for removing cells from a fermentation broth obtained by culturing a microorganism belonging to the genus Escherichia through a membrane to separate the cells, comprising adding polyethyleneimine to the fermentation broth to form a mixture, and then filtering the mixture through the membrane to separate the cells, said method resulting in improving the membrane permeation rate compared to when no polyethyleneimine is added.
