Bioengineering of anaerobic digestion for volatile fatty acids, hydrogen or methane production: A critical review

Anaerobic organic acid production of food waste in once-a-day feeding and drawing-off bioreactor

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.

Multi-stage cstr bioreactor system equipped with cell recycle unit

A multi-stage CSTR(continuous stirred tank reactor) bio-reactor system is provided to obtain a highly concentrated product by mounting an upflow packed-bed cell re-circulation device inside a reactor and operating the reactor in a multi-stage, thereby more economically and productively culturing microorganisms. A multi-stage CSTR bio-reactor system comprises: a plurality of bio-reactors(1,2,3); and an upflow packed-bed cell re-circulation device which is mounted on each of the bio-reactors. The system further comprises an outside pure oxygen regeneration device for supplying highly pure oxygen when the cell is an aerobic microorganism.
