Abstract (en)
[origin: WO2022012843A1] The invention relates to a process and a bioreactor for carrying out the process, comprising a sparger device that is in the form of a spillway-type airlift system. The bioreactor is suitable for anaerobic, aerobic and micro-air avid fermentation processes. The aeration device is preferably self-priming and allows recycling of gas by recirculation, the required gas supply being decoupled from the sparging intensity and the energy input, and the bioreactor is therefore suitable for use with gaseous substrates.
