Abstract

Ultrafiltration was used to pretreat colistin fermentation broth.According to the characteristics of the material and comparison of their ultrafiltration separation performance,polyether sulphone ultrafiltration membrane(MWCO=10 000) was selected.The optimum operating parameters had been determined: pressure was 0.3 MPa,pH was 6.0.Under these optimum parameters,the protein rejected ratio was 96%,absorbency was 0.185,and part of the pigment had been removed.

Key words： fermentation broth; polyether sulphone; ultrafiltration; optimization
