  • MULTI-STAGE CSTR BIOREACTOR SYSTEM EQUIPPED WITH CELL RECYCLE UNIT
    Publication number: 20100041124
    Abstract: The present invention relates to a single CSTR bioreactor equipped with a cell recycle unit, and a multi-stage CSTR bioreactor system in which 2-7 such single CSTR bioreactors are connected in series with each other. According to the present invention, multi-stage fermentation is carried out in the bioreactor equipped with the cell recycle unit, and thus the production of products (alcohols, organic acids, antibiotics, recombinant proteins, etc.) by anaerobic or aerobic microbial fermentation can be increased, and in addition, a final product can be obtained at high concentration, thus improving the productivity and economic efficiency of a microbial process.
