Abstract
PURPOSE: To prepare the titled substance in high efficiency, by culturing a mutant belonging to Pseudomonas genus and resistant ethionine and α-aimno-β- hydroxy-valeric acid in a medium containing methanol as carbon source.
CONSTITUTION: L-methionine is prepared by culturing a mutant belonging to Pseudomonas genus and resistant to ethionine and α-amino-β-hydroxyvaleric acid, e.g. Pseudomonas sp.FEA44 (FERM-P No.5842) in a medium containing a carbon source comprising methanol, a nitrogen source such as aqueous ammonia, nitric acid, etc., and nutrients such as vitamin B12 under aerobic conditions. The produced L-methionine is separated from the cultivation liquid by using an ion exchange resin, etc.
