摘要：

Experiments were carried out with Z. mobilis immobilized on ‐γ‐alumina pellets in a continuous reactor for potable alcohol production. It was found that ‐γ‐alumina was a suitable support for continuous ethanol production processes. Specifically, an ethanol productivity (calculated on the basis of liquid volume) of 23.8 g/L/hr was achieved at 0.88 hr−1dilution rate, 159 g/L invert sugar content and 43.7% conversion, using raisin extracts as feed material. Similar productivities were obtained with media containing glucose. Biomass productivity, yield and free cells concentration in glucose and raisin extracts were examined. Ethanol production was constant during the time the system was operated, a period of over 60 days. Copyright © 1990, Wiley Blackwell. All rights reserved
