The immobilized cell tubular tormentor was prepared by wood chips or alginate gel. Investigations of characterization of the performance of ethanol fermentation in the immobilized cell tubular tormentor were undertaken and the results were compared with those of other tormentors. The immobilized cell tormentor packed with alginate gel showed much higher ethanol productivity than that with wood chip. It was concluded that the immobilized cell tubular tormentor packed with alginate gel might offer better perspectives for continuous ethanol production than that with wood chip.

A tubular tormentor was prepared by packing the wood chips and pumping the yeast solution of Saccharomyces formosensis in a tubular column. Investigations to characterize the ethanol fermentation in the immobilized cell tubular fermentor and to compare such a fermentors with other type fermentors were undertaken. Ethanol productivity of 24.4g EtOH/$\ell$.hr has been obtained from glucose substrate. This productivity is higher or compared favourably with that reported in immobilized bio-reactors.
