Freeze-dried cell factories led to improved results as compared with non-freeze dried. When lactase was substituted with L. casei, ethanol and lactic acid were produced simultaneously at high concentrations, but in a much longer fermentation time. The cell factories can be considered as models for white biotechnology using lactose containing raw materials. This suggested cell factory model can be applied for other bioconversions using the appropriate enzymes and cells, in the frame of White Biotechnology without genetic modificatio
