A cone type of tower fermentor loaded with flocculating Sacchromyces uvarum was used to study the fermentor performance. The performance of cone type fermentor was compared with those of other fermentors. The maximum yeast concentration in the cone type of tower fermentor was 35.9-43.0g/1.hr and the maximum ethanol productivity was 14.75g/1.hr at the dilution rate 0.26 hr-1. The ethanol yield was 0.446-0.472g ETOH/g Glucose. It was concluded that a cone type of tower fermentor might offer better perspectives for continous etanol fermentation.
