Ultrafiltration of the food vinegar
Abstract
The polysulfone hollow fiber membranes have been studied for clarification of the Acetobacter culture broth. It has been found that ultrafiltration of the broth without additional pre-treatment is unefficient due to formation the gel-layer of high molecular weight biosynthesis byproduct (Mw = 2900 kD) on the membrane surface. The method for pre-treatment of the culture broth, increasing the average flux from 8-10 up to 20-25 l/m2h, has been proposed.
