Abstract
A method produces a chemical through continuous fermentation including: (a) culturing a cell in a culture medium in a fermentor to ferment a feedstock to produce a chemical; (b) conducting filtration of the culture medium with a separation membrane module; (c) separating a permeate containing the chemical from the culture medium while retaining a non-permeated liquid in the fermentor, and (d) supplying a gas from at least one of a lower portion of the separation membrane module and a pipe communicating between the fermentor and the separation membrane module to adjust a gas linear velocity in the separation membrane module to 0.15 cm/s to 70 cm/s while supplying the separation membrane module with a liquid.
