摘要

Provided are a method of recovering L-threonine from the fermentation broth of an L-threonine producing microorganism, comprising: separating microbial bodies from the L-threonine containing fermentation broth obtained by culturing an L-threonine producing microorganism and filtering the separated fermentation broth to obtain a filtrate; concentrating the filtrate; and reacting the concentrated filtrate with a nonsolvent to obtain crystalline L-threonine, crystalline L-threonine recovered by the method, and a feed additive containing the crystalline L-threonine recovered by the method.
