ALCOHOL PRODUCTION PROCESS

摘要

The invention relates to the microbial fermentation of gaseous substrates, particularly to methods of mitigating and/or reducing alcohol toxicity effects on a microbial culture at elevated alcohol concentrations during fermentation. The invention relates particularly to microbial fermentation of substrates comprising CO and the effects of alcohol toxicity are reduced or mitigated by maintaining the temperature below the optimum operating temperature by cooling the fermentation broth.
