Abstract

Solid-liquid separation is an important step for the separation of nisin from the fermentation broth. This paper studied the application of ceramic membrane filtration to remove the solid. Experimental results indicated that the solid removal ratio was above 99% at pH 2.5, 40-50 °C, 0.1 Mpa, recovery of nisin being 84.4%, and while at pH 2.5 HCl was added to dilute the residue in the later stage. Compared to the recovery without the diluted residue, the yield increased 17.4%.
