PROCESS FOR THE PRODUCTION OF CARBON DIOXIDE AND ETHANOL BY CONTINUOUS MULTI-STAGE FERMENTATION AND EQUIPMENT FOR PUTTING IT INTO PRACTICE

摘要

In a process for multiple-stage continuous fermentation of a medium inoculated with microorganisms such as bacteria and yeast, each fermentation stage has a system for retaining microorganisms. The biomass is conveyed continuously or intermittently from one fermentation stage to the next, or the volume of each fermentation stage, in particular the first stage, is such that the critical concentration of the metabolite cannot be reached at the nominal operating output of the fermentation system. Application to the production of carbonic acid and ethanol.
