Document Type and Number:
WIPO Patent Application WO/2024/053285
Kind Code:
A1
Abstract:
According to the present invention, a method for controlling an intermediate interface during extraction and fermentation includes an extraction and fermentation process in which, in the same tank, a saccharified liquid is fermented using microorganisms in a lower phase to produce a target product, and the produced target product is extracted and moved by an extractant of an upper phase. An extraction and fermentation tank that is used in the extraction and fermentation process comprises a stirrer having one or more stages of stirring blades for each phase, and during the extraction and fermentation process, the power required for stirring with respect to the total volume of the solution contained in the extraction and fermentation tank is controlled so as to be less than 90 W/m3.
