Title:
METHOD FOR PRODUCING POLYHYDROXYALKANOATE, POLYHYDROXYALKANOATE PRODUCED USING SAME, AND DRY FERMENTER FOR PRODUCING POLYHYDROXY ALKANOATE
Document Type and Number:
WIPO Patent Application WO/2023/055109
Kind Code:
A1
Abstract:
Disclosed are a method for producing a polyhydroxyalkanoate, a polyhydroxyalkanoate produced using same, and a dry fermenter for producing a polyhydroxyalkanoate. The present invention is characterized by comprising: a step for producing a concentrated biomass fermentation broth containing a carboxylate produced by the dry fermentation of biomass; and a step for producing a polyhydroxyalkanoate by culturing a polyhydroxyalkanoate (PHA)-producing microorganism in the concentrated biomass fermentation broth, wherein, in the step for producing the polyhydroxyalkanoate, the reducing power for producing the polyhydroxyalkanoate is controlled according to the concentration of the carboxylate.
