PROBLEM TO BE SOLVED: To provide a method for producing DL-methionine from 2-amino-4-methylthiobutyl amide (methionine amide) by using a microorganism catalyst having amide-hydrolyzing activity. SOLUTION: DL-methionine is efficiently produced from 2-amino-4-methylthiobutyl amide (methionine amide) by bringing a thermophilic microorganism, e.g., a microorganism belonging to the genus Sulfolobus and having amide-hydrolyzing enzymatic activity to react in a water-based medium at 61-95°C and partly recovering generated ammonia from the water-based medium.
