Summary

Productivity of the fermentation of lactose to ethanol byKluyveromyces fragilis has been significantly improved by coupling a cross-flow membrane module to the primary fermentor in a semi-closed loop configuration. At a cell concentration of 90g/L in the bioreactor and inlet lactose concentration of 150g/L, productivity was 240gETOH/L/hr at dilution rate of 6 hr-1. This was 80 times better than batch fermentation.
