摘要：
A method of producing a chemical by continuous fermentation includes a fermentation step of converting a fermentation feedstock to a fermentation liquid containing a chemical by fermentation on cultivation of a microorganism; a membrane separation step of recovering the chemical as a filtrate by a separation membrane from the fermentation liquid; a concentrating step of obtaining a permeate and a concentrate containing the chemical by a reverse osmosis membrane from the filtrate; and/or a purification step of distilling the filtrate to increase a purity of the chemical, in which, cleaning etc. of the separation membrane in the membrane separation step is preformed by using the permeated liquid from the reverse osmosis membrane in the concentrating step and/or the condensed liquid in the purification step.
