Title:
METHOD FOR PREPARING CITRULLINE
Document Type and Number:
WIPO Patent Application WO/2015/111597
Kind Code:
A1
Abstract:
 Disclosed are a method for preparing citrulline that makes it possible to produce citrulline efficiently, and a method for producing a citrulline-containing composition containing citrulline at high concentration. Also disclosed are a method for culturing and a method for fermenting microorganisms having increased conversion efficiency from arginine to citrulline, and a culture method that increases the concentration of microorganisms having the ability to produce citrulline. Citrulline can be produced efficiently by inoculating medium with microorganisms having the ability to produce citrulline and culturing at a higher temperature than usual, and by adding microorganisms having the ability to produce citrulline to a raw material and fermenting at a higher temperature than usual. The conversion efficiency from arginine to citrulline can also be increased, or the concentration of microorganisms can be increased, by adding arginine to medium or raw material and culturing or fermenting microorganisms having the ability to produce citrulline, and by culturing by controlling the pH of the medium.
