    • PURPOSE: A manufacturing method of L-methionine and related products is provided to be used for producing methionine and by-products thereof from methionine precursors. CONSTITUTION: A manufacturing method of L-methionine and related product comprises the following steps: producing L-methionine and acetate supply source by processing O- acetyl homoserine (OAHS) fermentation liquid(1002) as enzyme; forming residual solution which includes the acetate supply source and the L-methionine(1022) obtained by separating a part of L-methionine from one part of the acetate supply source; and collecting(1050) acetate in which a part of the acetate supply source from the residual solution. The manufacturing method additionally includes a step of using the acetate which is collected as a reagent.
