Title: METHOD FOR FERMENTATION-PRODUCTION OF PENTANEDIAMINE COMPRISING CARBON DIOXIDE STRIPPING TECHNIQUE
Abstract:
A method for fermentation-production of a pentanediamine, comprising: culturing a cell expressing a lysine decarboxylase to obtain a whole cell fermentation broth comprising a pentanediamine; and extracting the pentanediamine from the whole cell fermentation broth, and stripping the whole cell fermentation broth of carbon dioxide contained therein before adding a strong base. The method greatly increases a production volume of the pentanediamine.
