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.

A continuous process for producing a metabolite from a carbohydrate substrate which comprises the steps of: (A) pulverizing the carbohydrate substrate; (B) liquefying and saccharifying the pulverized substrate; (C) continuously fermenting the lique-saccharified substrate in a fermentor, in the presence of biological cells and a culture medium to produce a fermentation product mixture; and (D) recovering the metabolite from the fermentation product mixture; wherein the fermentor is equipped with a moving filter having an opening size ranging from 50 to 2,000 mesh and the biological cells are flocculent cells maintained at a concentration ranging from 90 to 160 g/l by the moving filter during the fermentation step.
