Ethanol producing bacteria Zymomonas mobilis (strain 3881 and 3883) were used in batch and continuous fermentation as free cells as well as immobilized in alginate beads. Continuous fermentation helped to increase the productivity of fermentors significantly and continuous fermentation with immobilized in alginate cells gave as high productivities as 49,5 g/dm3*h.
