Fermentation production of L-threonine
摘要:
An improved method for the fermentative production of L-threonine in a high yield, which comprises cultivating a methionine metabolism-antagonist resistant mutant of Serratia marcescens having L-threonine productivity in a broth to form and accumulate L-threonine therein and recovering accumulated L-threonine from the broth.
