Disclosed is a method for producing a chemical product by a continuous fermentation method and an apparatus for producing the same, which can stably maintain high productivity over a long period of time under simple operation conditions. A fermentation fermentation broth is separated into a filtrate and an unfiltered liquid by a separation membrane, and a chemical product, which is a desired fermentation product, is recovered from the filtrate and the unfiltered liquid is retained or refluxed in the fermentation broth. This is a method for producing chemicals by using a porous membrane that has high permeability and high cell blocking rate as a separation membrane and is difficult to block, and is filtered at a low transmembrane pressure difference, so that it can be stably produced at low cost. This is a method for producing a chemical product by continuous fermentation capable of remarkably improving the production efficiency of the chemical product by fermentation. [Selection] Figure 1 |
