Abstract
A metabolite, e.g., ethanol, is continuously produced from low cost carbohydrate substrates by a process which comprises pulverizing the carbohydrate substrate; liquefying and saccharifying the pulverized substrate; continuously fermenting the lique-saccharified substrate in a fermentor equipped with a moving filter, in the presence of flocculent biological cells maintained at a concentration ranging from 90 to 160 g/l by using the moving filter and a culture medium to produce a fermentation product mixture; and recovering the desired metabolite from the fermentation product mixture.
