Abstract

Lactobacillus bulgaricus was immobilized in the shell side of an industrial hollow-fiber ultrafiltration module. Acid whey permeate, containing 46 g/L lactose supplemented with 10 g/L yeast extract, was pumped through the tube side at dilution rates of 0.2–2.5/h. At a cell concentration of 100 g/L, productivity was 1.5–5 g lactic acid/L/h.
